9DB1904B Datasheet 19 Output Differential Buffer

Manufacturer: Renesas

Overview: Datasheet 19 Output Differential Buffer for PCIe Gen2 and QPI.

Datasheet Details

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.
