Overview

The 9DB1904 is electrically compatible to the Intel DB1900GS Differential Buffer buffer provides 19 output clocks for PCI-Express Gen2 or Intel QPI 6.4GT/s applications. A differential clock from a CK410B+ main clock generator, such as the ICS932S421 drives the 9DB1904.

  • 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 CK
