9DB1904B Datasheet (IDT) - 19 Output Differential Buffer

9DB1904B, 19 Output Differential Buffer

The 9DB1904 is electrically compatible to the Intel DB1900GS Differential Buffer Specification.This buffer provides 19 output clocks for PCI-Express Gen2 or Intel QPI 6.4GT/s applications.

A differential clock from a CK410B+ main clock generator, such as the ICS932S421 drives the 9DB1904.
