Block Diagram

Description

The new PI6C49021 is a high integration clock generator intended

for all kinds of embedded applications and networking application

with PCIe interface. The device is the most cost effective way

to generate multi-frequencies and multi-outputs clocks from

a 25MHz crystal and reference clock. The device can generate

100MHz HCSL clock, single-ended clocks includes 24MHz,

25MHz, 50HMz, 125HMz, and low jitter 25MHz LVPECL clock.
