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. The 9DB190.
