Six Output Differential Buffer for PCIe Gen 2
DATASHEET
9DB106
Description
Features/Benefits
The 9DB106 zero-delay buffer supports PCIe Gen1 and Gen2
clocking requirements. The 9DB106 is driven by a differential SRC
output pair from an IDT CK410/CK505-compliant 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. An SMBus interface allows control of
the PLL bandwidth and bypass options, while 2 clock request
(CLKREQ#) pins make the 9DB106 suitable for Express Card
applications.
CLKREQ# pin for outputs 1 and 4/ supports Express Card
applications
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
