MK2703B
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.
Features
Packaged in 8-pin SOIC Available in RoHS compliant package Uses an inexpensive, fundamental mode crystal or clock Patented zero ppm synthesis error in all clocks All frequencies are frequency locked Advanced, low power, sub-micron CMOS process Operating voltage of 3.3 V or 5 V Industrial temperature version available
