Frequency Gearing Clock for CPU, PCIe Ge n1 & FBD DATASHEET 9FG1901H Descripti on Features/Benefits The 9FG1901H fol lows the Intel DB1900G Differential Buf fer Specification. This buffer provides 19 output clocks for CPU Host Bus, PCI -Express, or Fully Buffered DIMM applic ations. The outputs are configured with two groups. Both groups, DIF_(16:0) an d DIF_(18:17) can be equal to or have a gear ratio to the input clock. A diffe rential CPU clock from a CK410B+ main c lock generator, such as the ICS932S421, drives the ICS9FG1901. The 9FG1901H ca n provide outputs up to 400MHz. • • • • • • Power up default is all outputs in 1:1 mode DIF_(16:0) can be “gear-shifted” from the input CPU Host Cloc
