描述

The IDT9FG1904B-1 follows the Intel DB1900GS Differential Buffer Specification, except for the output groupings. This buffer provides 19 output clocks for CPU Host Bus, PCI-Express, 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 IDT932S421, drives the IDT9FG1904B-1. The IDT9FG1904B-1 can provide outputs up to 400MHz.
