Overview

The 9DB1904 is electrically compatible to the Intel DB1900GS Differential Buffer Specification. This buffer provides 19 output clocks for PCI-Express Gen2 or Intel QPI 6.4GT/s applications.

  • Power up default is all outputs in 1:1 mode/No SMBus programming
  • Spread spectrum compatible/EMI reductions
  • Supports output frequencies up to 400 MHz in bypass mode/flexible fanout buffer
  • 8 Selectable SMBus addresses/no SMBus segmentation required
  • SMBus address determines PLL or Bypass mode/pin savings
  • Dedicated VDDA and CKPWRGD_PD# pins/easy board design Functionality at Power Up (PLL Mode) 100M_133M# CLK_IN MHz 1 100MHz 0 133MHz
