BLU-RAY DISC VCXO
Description
The MK3732-22 is a low-cost, low-jitter, 3.3 Volt VCXO
designed to replace expensive VCXOs. Using an advanced
clock synthesizer with on-chip Phase-Locked Loops (PLLs),
MK3732-22 generates six high-quality clock outputs from a
low cost, 13.5 MHz crystal. It can replace multiple voltage
controlled crystal oscillators, saving board space and cost.
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 ±100 ppm. The higher intrinsic VCXO gain of the
MK3732-22 helps compensate for the reduced pullability of
a low quality crystal and is ideal for PWM applications.
