PI6LC4833
Clock Generator for Power PC
Description
The PI6LC4833 implements Pericom's advanced LC VCO tech-
nology and is specifically designed for Power PC network pro-
cessor (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.
