描述

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 applications. A differential clock from a CK410B+ main clock generator, such as the 932S421 drives the 9DB1904. The 9DB1904 can provide outputs up to 400 MHz in Bypass Mode.
