9DB1933 - Nineteen Output Differential Buffer

General Description

The 9DB1933 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1.

The 9DB1933 is driven by a differential SRC output pair from an IDT 932S421, 932SQ420, or equivalent, main clock generator.

Key Features

  • 19 - 0.7V current mode differential HCSL output pairs Features/Benefits.
  • 8 Selectable SMBus Addresses/Mulitple devices can share the same SMBus Segment.
  • 11 dedicated and 3 group OE# pins/Hardware control of the outputs.
  • 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.

Nineteen Output Differential Buffer for PCIe Gen3 DATASHEET 9DB1933 Recommended Application 19 output PCIe Gen3 zero-delay/fanout buffer General Description The 9DB1933 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1. The 9DB1933 is driven by a differential SRC output pair from an IDT 932S421, 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. Output Features • 19 - 0.
