Block Diagram
Power Groups
The ICS9FG1901 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 CK410 or CK410B main clock
generator, such as the ICS954101 or ICS932S401, drives the ICS9FG1901. The ICS9FG1901 can provide outputs up to
400MHz.
