MK2703B Datasheet, PDF (1/7 Pages) Integrated Device Technology – PLL AUDIO CLOCK SYNTHESIZER

PLL AUDIO CLOCK SYNTHESIZER
DATASHEET
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
