Description
The MK2703B is a low-cost, low-jitter, high
performance PLL clock synthesizer designed to
replace oscillators and PLL circuits in set-top box and
multimedia systems. Using ICS’ patented analog
Phase Locked Loop (PLL) techniques, the device uses
a 27 MHz crystal or clock input to produce a buffered
reference clock and a selectable audio clock.
ICS manufactures the largest variety of Set-Top Box
and multimedia clock synthesizers for all applications.
Consult ICS to eliminate VCXOs, crystals and
oscillators from your board.

... X2 XO External Components Decoupling Capacitor As with any high-performance mixed-signal IC, the MK2703B must be isolated from system power supply noise to perform optimally. A decoupling capacitor of 0.01µF must be connected between VDD and GND on pins 2 and 3. It must be connected close to the MK2703B to minimize lead inductance. No external power supply filtering is required for the MK2703B ...
