System and Peripheral
Clock Generator
Features
Description
• One 14.318 MHz Reference Clock
• One 100 MHz System Clock
• One 83.33 MHz MPEG Encoder Clock
• One 25 MHz Ethernet Clock
• Two 48 MHz Clocks
PI6C22392-03 is a low jitter, high performance clock generator
which supports system and peripheral chips. Using Pericom's PLL
technology,thePI6C22392-03acceptsa14.318MHzreferenceinput
and generates both a very accurate, stable system and peripheral
clock. Clock outputs are tri-stated when OE is LOW.
• Low jitter Design:
