MK3713
Low Cost 3.3 Volt VCXO
ICR O CLOC K
Features
Description
The MK3713 is ICS/MicroClock’s lowest cost,
low jitter, high performance 3.3 Volt VCXO
designed to replace expensive VCXO modules.
The on-chip Voltage Controlled Crystal Oscillator
accepts a 0 to 3.3 V input voltage to cause the
output clocks to vary by ±100 ppm. Using
ICS/MicroClock’s patented VCXO and analog
Phase-Locked Loop (PLL) techniques, the device
uses an inexpensive external pullable crystal input
to produce the output clock.
• Packaged in 8 pin SOIC
• Ideal for T1 and E1 VCXOs
• Output range of 1.25 MHz to 10 MHz
• For a 10-20 MHz output range, use the MK3711
• For higher than 20 MHz, use the MK3732-05
• 3.3 V only operating voltage
• Uses an inexpensive 10 - 20 MHz external crystal
• On-chip VCXO (patented) with pull range of
200ppm (minimum)
ICS/MicroClock manufactures the largest variety
of communications, set-top box, and multimedia
clock synthesizers for all applications. If more
clock outputs are needed, see the MK3732 or
MK377x family of parts. Consult
ICS/MicroClock to eliminate VCXOs, crystals
and oscillators from your board.
• VCXO tuning voltage of 0 to 3.3 V
• 12mA output drive capability at TTL levels
• Advanced, low power, sub-micron CMOS process

Notes: 1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. With a ICS/MicroClock approved pullable crystal.
External Components
The MK3713 requires a minimum number of external components for proper operation. A decoupling
capacitor of 0.01µF should be connected between VDD and GND on pins 2 and 4, as close to the
MK3713 as possible. A series termination resistor of 33 Wmay be used for the clock output. The input
crystal must be connected as close to the chip as possible. The input crystal should be a parallel mode,
pullable, AT cut, 13.5 MHz, with 14 pF load capacitance. Consult ICS for recommended suppliers.
IMPORTANT - read application note MAN05 before laying out the PCB.
