General Description
Output Features
The 9DB1933 zero-delay buffer supports PCIe Gen3
requirements, while being backwards compatible to PCIe Gen2
and Gen1. The 9DB1933 is driven by a differential SRC output
pair from an IDT 932S421, 932SQ420, or equivalent, main
clock generator. It attenuates jitter on the input clock and has a
selectable PLL bandwidth to maximize performance in systems
with or without Spread-Spectrum clocking.

Key Specifications
Cycle-to-cycle jitter <50ps
Output-to-output skew < 150 ps
PCIe Gen3 phase jitter < 1.0ps RMS
Features/Benefits
8 Selectable SMBus Addresses/Mulitple devices can share
the same SMBus Segment
11 dedicated and 3 group OE# pins/Hardware control of the
outputs
PLL or bypass mode/PLL can dejitter incoming clock
Selectable PLL bandwidth/minimizes jitter peaking in
downstream PLL's
Spread Spectrum Compatible/tracks spreading input clock
for low EMI
SMBus Interface/unused outputs can be disabled
Supports undriven differential outputs in Power Down mode
for power management
Recommended Application
19 output PCIe Gen3 zero-delay/fanout buffer
