Additional preview pages of the 9DB1904B datasheet.

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.

A differential clock from a CK410B+ main clock generator, such as the ICS932S421 drives the 9DB1904.

Benefits.
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.
