Features

  • Loss of Signal (LOS) output; supports fault tolerant systems
  • Supports PCIe Gen 1–5 CC and IR in fanout mode
  • Supports PCIe Gen 1–5 CC in High Bandwidth Zero Delay Buffer (ZDB) mode
  • Direct connection to 100Ω transmission lines; saves 24 resistors compared to standard PCIe devices
  • Spread spectrum tolerant; allows reduction of EMI
  • Pin/SMBus selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
  • Easy AC coupling to other logic families, see application note AN-891.
  • Space saving 5mm × 5mm 40-VFQFPN; minimal board space

Description

The 9DBL0643 zero-delay/fanout buffer is a low-power high-performance member of Renesas' full-featured PCIe family. The buffer supports PCIe Gen 1–5 and provides a Loss of Signal (LOS) indicator. The device is an easy upgrade from the 9DBL0641.
