VCXO AND MULTIPLIER
IDT™ / ICS™ VCXO AND MULTIPLIER
Description
The MK3732-10 is a low cost, low jitter, high performance
VCXO and PLL clock synthesizer designed to replace
expensive discrete VCXOs and multipliers. The patented
on-chip Voltage Controlled Crystal Oscillator accepts a 0 to
3.3 V input voltage to cause the output clocks to vary by
±115 ppm. Using ICS’ analog/digital Phase-Locked Loop
(PLL) techniques, the device uses an inexpensive 27 MHz
pullable crystal input to produce three output clocks.
ICS manufactures the largest variety of MPEG clock
synthesizers for all applications. Consult ICS to eliminate
VCXOs, crystals, and oscillators from your board.
