描述 Description

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.

Features/Benefits

? 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
