Renesas Electronics 9DBL PCIe Zero-Delay Buffers

Renesas Electronics 9DBL PCIe Zero-Delay Buffers are 3.3V devices that support PCIe Gen1-4 Common Clocked (CC) systems. The 9DBL also supports PCIe Gen2 Separate Reference Independent Spread (SRIS) systems. The buffers provide a direct connection to 85Ω or 100Ω transmission lines with a choice of integrated output terminations. Renesas Electronics 9DBL PCIe Zero-Delay Buffers can be factory programmed with a user-defined power-up default SMBus configuration.

Features

  • Direct connection to 100Ω (xx41, xx42) or 85Ω (xx51, xx52) transmission lines
  • SMBus-selectable features allow optimization to customer requirements:
  • Control input polarity
  • Control input pull up/downs
  • Slew rate for each output
  • Differential output amplitude
  • Output impedance for each output
  • 50MHz, 100MHz, or 125MHz operating frequency
  • Customer defined SMBus power up default can be programmed into P1 device; allows exact optimization to customer requirements
  • OE# pins; support DIF power management
  • HCSL-compatible differential input; can be driven by common clock sources
  • Spread Spectrum tolerant; allows reduction of EMI
  • Pin/SMBus selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
  • Outputs blocked until PLL is locked; clean system start-up
  • Device contains default configuration; SMBus interface not required for device operation
  • Three selectable SMBus addresses; multiple devices can easily share an SMBus segment
  • Space-saving 24-pin 4x4mm VFQFPN; minimal board space
