Frequency Gearing Clock for CPU, PCIe Gen1 & FBD DATASHEET 9FG1901H Description Features/Benefits The 9FG1901H follows the Intel DB1900G Differential Buffer Specification. 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_(16:0) and DIF_(18:17) 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 ICS9FG1901. The 9FG1901H can provide outputs up to 400MHz.
