Description

The 9DBV0631 is a member of Renesas’ 1.8V

Very-Low-Power (VLP) PCIe family. The device has 6 output

enables for clock management and 3 selectable SMBus

addresses.

Features/Benefits

• LP-HCSL outputs; save 12 resistors compared to standard

PCIe devices

• 55mW typical power consumption in PLL mode; minimal

power consumption

• Outputs can optionally be supplied from any voltage

between 1.05 and 1.8V; maximum power savings

• OE# pins; support DIF power management

• HCSL-compatible differential input; can be driven by

common clock sources

• Spread Spectrum tolerant; allows reduction of EMI

• Programmable Slew rate for each output; allows tuning for

various line lengths

• Programmable output amplitude; allows tuning for various

application environments

• Pin/software selectable PLL bandwidth and PLL Bypass;

minimize phase jitter for each application

• Outputs blocked until PLL is locked; clean system start-up

• Configuration can be accomplished with strapping pins;

SMBus interface not required for device control

• 3.3V tolerant SMBus interface works with legacy controllers

• Space saving 5 × 5mm 40-VFQFPN; minimal board space

• 3 selectable SMBus addresses; multiple devices can easily

share an SMBus segment
