PI6LC4833
Clock Generator for Power PC
Description
The PI6LC4833 implements Pericom's advanced LC VCO technology and is specifically designed for Power PC network processor (Freescale MPC8548, MPC8572, AMCC 460, AMI732). This high performance device is optimized to generate CPU core/ PCI clock, high performance PCIe Gen1/2 Clock, SRIO, Gigabit Ethernet’s MAC and PHY clock. All outputs are generated from 25MHz external clock input or crystal.
