Overview
PRELIMINARY INFORMATION MK3713 Low Cost 3.
3 Volt VCXO 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.
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.
Features • 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.
