DESCRIPTION  
The CDC2586 is a high-performance, low-skew, low-jitter clock driver. It uses a phase-lock loop (PLL) to  
precisely align, in both frequency and phase, the clock output signals to the clock input (CLKIN) signal. It is  
specifically designed for use with popular microprocessors operating at speeds from 50 MHz to 100 MHz or  
down to 25 MHz on outputs configured for half-frequency operation. Each output has an internal 26-series  
resistor that improves the signal integrity at the load. The CDC2586 operates at nominal 3.3-V VCC  
.

The feedback input (FBIN) synchronizes the output clocks in frequency and phase to CLKIN. One of the twelve  
output clocks must be fed back to FBIN for the PLL to maintain synchronization between CLKIN and the outputs.  
The output used as feedback is synchronized to the same frequency as CLKIN.  
The Y outputs can be configured to switch in phase and at the same frequency as CLKIN. Select inputs (SEL1,  
SEL0) configure up to nine Y outputs, in banks of three, to operate at one-half or double the CLKIN frequency  
depending on which output is fed back to FBIN (see Table 1 and Table 2). All output signal duty cycles are  
adjusted to 50% independent of the duty cycle at CLKIN.  
Output-enable (OE) provides output control. When OE is high, the outputs are in the high-impedance state.  
When OE is low, the outputs are active. TEST is used for factory testing of the device and can be used to bypass  
the PLL. TEST should be strapped to GND for normal operation.  
Unlike many products containing PLLs, the CDC2586 does not require external RC networks. The loop filter for  
the PLL is included on-chip, minimizing component count, board space, and cost.  
Because it is based on PLL circuitry, the CDC2586 requires a stabilization time to achieve phase lock of the  
feedback signal to the reference signal. This stabilization time is required following power up and application of a  
fixed-frequency, fixed-phase signal at CLKIN, as well as following any changes to the PLL reference or feedback  
signals. Such changes occur upon change of the select inputs, enabling of the PLL via TEST, and upon enable  
of all outputs via OE.  
The CDC2586 is characterized for operation from 0°C to 70°C.  
DETAILED DESCRITPION OF OUTPUT CONFIGURATIONS  
The voltage-controlled oscillator (VCO) used in the CDC2586 PLL has a frequency range of 100 MHz to 200  
MHz, twice the operating frequency range of the CDC2586 outputs. The output of the VCO is divided by two and  
four to provide reference frequencies with a 50% duty cycle of one-half and one-fourth the VCO frequency. The  
SEL0 and SEL1 inputs select which of the two signals are buffered to each bank of device outputs.  
One device output must be externally wired to FBIN to complete the PLL. The VCO operates such that the  
frequency and phase of this output matches that of the CLKIN signal. In the case that a VCO/2 output is wired to  
FBIN, the VCO must operate at twice the CLKIN frequency resulting in device outputs that operate at either the  
same or one-half the CLKIN frequency. If a VCO/4 output is wired to FBIN, the device outputs operate at twice or  
the same as the CLKIN frequency.

DESCRIPTION  
NAME  
NO.  
Clock input. CLKIN is the clock signal to be distributed by the CDC2586 clock-driver circuit. CLKIN  
provides the reference signal to the integrated PLL that generates the clock output signals. CLKIN must  
have a fixed frequency and fixed phase for the PLL to obtain phase lock. Once the circuit is powered  
up and a valid CLKIN signal is applied, a stabilization time is required for the PLL to phase lock the  
feedback signal to its reference signal.

CLR is used for testing purposes only.  
Feedback input. FBIN provides the feedback signal to the internal PLL. FBIN must be hardwired to one  
of the 12 clock outputs to provide frequency and phase lock. The internal PLL adjusts the output clocks  
to obtain zero phase delay between FBIN and CLKIN.  
FBIN  
Output enable. OE is the output enable for all outputs. When OE is low, all outputs are enabled. When  
OE is high, all outputs are in the high-impedance state. Since the feedback signal for the PLL is taken  
directly from an output, placing the outputs in the high-impedance state interrupts the feedback loop;  
therefore, when a high-to-low transition occurs at OE, enabling the output buffers, a stabilization time is  
required before the PLL obtains phase lock.

Output configuration select. SEL0 and SEL1 select the output configuration for each output bank (e.g.,  
1/2×, 1×, or 2×) (see Table 1 and Table 2).

TEST is used to bypass the PLL circuitry for factory testing of the device. When TEST is low, all  
outputs operate using the PLL circuitry. When TEST is high, the outputs are placed in a test mode that  
bypasses the PLL circuitry. TEST should be strapped to GND for normal operation.  
Output ports. These outputs are configured by the select inputs (SEL1, SEL0) to transmit one-half or  
one-fourth the frequency of the VCO. The relationship between the CLKIN frequency and the output  
frequency is dependent on the select inputs and the frequency of the output being fed back to FBIN  
(see Table 1 and Table 2). The duty cycle of the Y output signals is nominally 50%, independent of the  
duty cycle of CLKIN. Each output has an internal series resistor to dampen transmission-line effects  
and improve the signal integrity at the load.

and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should  
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are  
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.  
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard  
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where  
mandated by government requirements, testing of all parameters of each product is not necessarily performed.  
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and  
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,  
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information  
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a  
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual  
property of the third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied  
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive  
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional  
restrictions.  
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all  
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not  
responsible or liable for any such statements.  
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably  
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing  
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and  
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products  
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be  
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in  
such safety-critical applications.  
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at  
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.  
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are  
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated  
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
