ICS9FG1904B-1 General Description
ThThe ICS9FG1904-1 follows the Intel DB1900GS Differential Buffer Specification, except for the output groupings and gear table. The gear table is a blend of the GS and GSO gearing. This buffer provides 19 output clocks for CPU Host Bus, PCIExpress, or Fully Buffered DIMM applications. The outputs are configured with two groups. Both groups, DIF_(14:0) and DIF_(18:15) can be equal to or have a gear ratio to the input clock. A differential CPU clock from a CK410B+ main clock generator, such as the ICS932S421, drives the ICS9FG1904-1. The ICS9FG1904-1 can provide outputs up to 400MHz.
