MPEG CLOCK SYNTHESIZER
Description
The ICS650-12 is a low cost, low-jitter, high-performance
clock synthesizer designed to produce fixed clock outputs of
13.5 MHz and 27.0 MHz, and four selectable clock outputs:
two Processor Clocks (PCLK1) and PCLK2), an Audio
Clock, and a Communications Clock (CCLK). Using analog
Phase-Locked Loop (PLL) techniques, the device uses a
27.0 MHz clock or fundamental crystal to produce clocks
ideal for Digital Video/MPEG-based applications.
