DB1200G Frequency Gearing Clock for Intel CPU, PCIe Gen1 & Fully Buffered DIMM Clocks

IDT9FG1201 follows the Intel DB1200G Differential Buffer Specification. This buffer provides 12 output clocks for CPU Host Bus, PCIe Gen1, or Fully Buffered DIMM applications. The outputs are configured with two groups. Both groups (DIF 9:0) and (DIF 11:10) 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 IDT9FG1201. The IDT9FG1201 can provide outputs up to 400MHz.

Features

  • Power up default is all outputs in 1:1 mode
  • DIF_(9:0) can be "gear-shifted" from the input CPU Host Clock
  • DIF_(11:10) can be "gear-shifted" from the input CPU Host Clock
  • Spread spectrum compatible
  • Supports output clock frequencies up to 400 MHz
  • 8 Selectable SMBus addresses
  • SMBus address determines PLL or Bypass mode
