General Description

The ICS9DB823B is compatible with the Intel DB800Q

Differential Buffer Specification. This buffer provides 8

PCI-Express SRC or 8 QPI clocks. The ICS9DB823B is

driven by a differential output pair from a CK410B+ or

CK509B main clock generator.

Recommended Application

DB800Q compatible part with PCIe Gen1, Gen 2 and QPI

support
