The Renesas Electronics 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.

6 - 0.7 V current mode differential output pairs (HCSL)
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
Cycle-to-cycle jitter < 50 ps
Output-to-output skew < 50 ps
