High-performance Clock Generator Series
DVD-Video Reference
Clock Generators
for Audio/Video Equipments
BU2280FV, BU2288FV, BU2360FV, BU2362FV
●Description
These clock generators are an IC generating three types of clocks - VIDEO, AUIDIO and SYSTEM clocks – necessary for
DVD player systems, with a single chip through making use of the PLL technology. Particularly, the AUDIO clock is a
DVD-Video reference and yet achieves high C/N characteristics to provide a low level of distortion factor.
●Features
1) Connecting a crystal oscillator generates multiple clock signals with a built-in PLL.
2) AUDIO clock of high C/N characteristics providing a low level of distortion factor
3) The AUDIO clock provides switching selection outputs.
4) Single power supply of 3.3 V
●Applications
DVD players

Common to BU2280FV、BU2288FV、BU2360FV and BU2362FV:
*1 Period-Jitter 1σ
This parameter represents standard deviation (=1 σ) on cycle distribution data at the time when the output clock cycles are
sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
*2 Period-Jitter MIN-MAX
This parameter represents a maximum distribution width on cycle distribution data at the time when the output clock cycles
are sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
*3 Output Lock-Time
The Lock-Time represents elapsed time after power supply turns ON to reach a 3.0V voltage, after the system is switched
from Power-Down state to normal operation state, or after the output frequency is switched, until it is stabilized at a specified
frequency, respectively.
BU2360FV, BU2288FV
∗4 This parameter represents lower and upper limit voltages at the Schmitt trigger input PIN having hysteresis characteristics
shown in figure below. The width requested by these differences is assumed to be a hysteresis width.

●Cautions on use (BU2362FV)
Basically, mount ICs to the printed circuit board for use. (If the ICs are not mounted to the printed circuit board, the
characteristics of ICs may not be fully demonstrated.)
Mount 0.1µF capacitors in the vicinity of the IC PINs between 1PIN (VDD2) and 2PIN (VSS2), 5PIN (AVDD) and 6PIN
(AVSS), 11PIN (DVSS) and 12PIN (DVDD), respectively.
For the fine-tuning of frequencies, insert several numbers of pF in the 7PIN and 8PIN to GND.
Depending on the conditions of the printed circuit board, mount an additional electrolytic capacitor between the power
supply and GND terminal.
For EMI protection, it is effective to put ferrite beads in the origin of power supply to be fed to BU2362FV from the
printed circuit board or to insert a capacitor (of 1Ω or less), which bypasses high frequency desired, between the
power supply and the GND terminal.
*Refer to the BU2362FV Example of application circuit for BU2288FV Example of application circuit.
Even though we believe that the example of recommended circuit is worth of a recommendation, please be sure to thoroughly
recheck the characteristics before use.
22/24
●Cautions on use
(1) Absolute Maximum Ratings
An excess in the absolute maximum ratings, such as applied voltage (VDD or VIN), operating temperature range (Topr),
etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit.
If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take
physical safety measures including the use of fuses, etc.
(2) Recommended operating conditions
These conditions represent a range within which characteristics can be provided approximately as expected. The
electrical characteristics are guaranteed under the conditions of each parameter.
(3) Reverse connection of power supply connector
The reverse connection of power supply connector can break down ICs. Take protective measures against the
breakdown due to the reverse connection, such as mounting an external diode between the power supply and the IC’s
power supply terminal.
(4) Power supply line
Design PCB pattern to provide low impedance for the wiring between the power supply and the GND lines.
In this regard, for the digital block power supply and the analog block power supply, even though these power supplies
has the same level of potential, separate the power supply pattern for the digital block from that for the analog block,
thus suppressing the diffraction of digital noises to the analog block power supply resulting from impedance common to
the wiring patterns. For the GND line, give consideration to design the patterns in a similar manner.
Furthermore, for all power supply terminals to ICs, mount a capacitor between the power supply and the GND terminal.
At the same time, in order to use an electrolytic capacitor, thoroughly check to be sure the characteristics of the
capacitor to be used present no problem including the occurrence of capacity dropout at a low temperature, thus
determining the constant.
(5) GND voltage
Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state.
Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric
transient.
(6) Short circuit between terminals and erroneous mounting
In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting
can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between terminals or
between the terminal and the power supply or the GND terminal, the ICs can break down.
(7) Operation in strong electromagnetic field
Be noted that using ICs in the strong electromagnetic field can malfunction them.
(8) Inspection with set PCB
On the inspection with the set PCB, if a capacitor is connected to a low-impedance IC terminal, the IC can suffer stress.
Therefore, be sure to discharge from the set PCB by each process. Furthermore, in order to mount or dismount the set
PCB to/from the jig for the inspection process, be sure to turn OFF the power supply and then mount the set PCB to the
jig. After the completion of the inspection, be sure to turn OFF the power supply and then dismount it from the jig. In
addition, for protection against static electricity, establish a ground for the assembly process and pay thorough attention
to the transportation and the storage of the set PCB.
(9) Input terminals
In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the
parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of
the input terminal. Therefore, pay thorough attention not to handle the input terminals, such as to apply to the input
terminals a voltage lower than the GND respectively, so that any parasitic element will operate. Furthermore, do not
apply a voltage to the input terminals when no power supply voltage is applied to the IC. In addition, even if the power
supply voltage is applied, apply to the input terminals a voltage lower than the power supply voltage or within the
guaranteed value of electrical characteristics.
(10) Ground wiring pattern
If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND
pattern from the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that
resistance to the wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of
the small-signal GND. Pay attention not to cause fluctuations in the GND wiring pattern of external parts as well.
(11) External capacitor
In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a
degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc.
