ICS9FG1201H

Frequency Generator for CPU, PCIe Gen1* & Fully Buffered

DIMM Clocks

Description

Features/Benefits

ICS9FG1201 follows the Intel DB1200G Differential Buffer

Specification. This buffer provides 12 output clocks for CPU Host

Bus, PCI Express, 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 CK410 or CK410B main clock generator,

such as the ICS954101 or ICS932S401, drives the ICS9FG1201.

ICS9FG1201 can provide outputs up to 400MHz.

•

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

Key Specifications

•

DIF output cycle-to-cycle jitter < 50ps

DIF output-to-output skew < 50ps within a group

DIF output-to-output skew < 100ns across all outputs

56-pin SSOP/TSSOP package

Available in RoHS compliant packaging
