19 Output Differential Buffer for PCIe Gen2 and QPI
1607C —04/19/11
19 Output Differential Buffer for PCIe Gen2 and QPI
1
Datasheet
Description
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. The 9DB1904 can provide
outputs up to 400MHz in Bypass Mode.
Key Specifications
DIF output cycle-to-cycle jitter < 50ps
DIF output-to-output skew < 150ps across all outputs
Features/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
