- Cycle-to-cycle jitter < 50 ps
- Output-to-output skew < 50 ps
説明
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.
