8-output Differential Buffer for PCIe Gen2

The 9DB803 is compatible with the Intel DB800v2 Differential Buffer Specification. This buffer provides 8 PCI Express Gen2 clocks. The 9DB803 is driven by a differential output pair from a CK410B+, CK505 or CK509B main clock generator.

Features

  • 8 - 0.7 V current-mode differential output pairs
  • Supports zero delay buffer mode and fanout mode
  • Bandwidth programming available
  • 50-100 MHz operation in PLL mode
  • 50-400 MHz operation in Bypass mode
  • Spread spectrum modulation tolerant, 0 to -0.5% down spread and +/- 0.25% center spread.
  • Supports undriven differential outputs in PD# and SRC_STOP# modes for power management.
  • Outputs cycle-cycle jitter < 50 ps
  • Outputs skew: 50 ps
  • Phase jitter: PCIe Gen1 < 86 ps peak to peak
  • Phase jitter: PCIe Gen2 < 3.0/3.1 ps rms
  • 48-pin SSOP/TSSOP package
  • RoHS compliant packaging
