The 9DB233 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1. The 9DB233 is driven by a differential SRC output pair from an IDT 932S421 or 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. An SMBus interface allows control of the PLL bandwidth and bypass options, while 2 clock request (OE#) pins make the 9DB233 suitable for Express Card applications.

Features

  • 2- 0.7 V HCSL differential output pairs
  • Phase jitter: PCIe Gen3 < 1 ps rms
  • Phase jitter: PCIe Gen2 < 3.1 ps rms
  • Phase jitter: PCIe Gen1 < 86 ps peak to peak
  • Supports zero delay buffer mode and fanout mode
  • Bandwidth programming available
  • 33-110 MHz operation in PLL mode
  • 10-110 MHz operation in Bypass mode
