Description

The 9DBV0441 is a member of Renesas’ SOC-Friendly

1.8V Very-Low-Power (VLP) PCIe family. It has integrated

output terminations providing Zo = 100? for direct

connection to 100? transmission lines. The device has 4

output enables for clock management, and 3 selectable

SMBus addresses.

Features/Benefits

? Direct connection to 100? transmission lines; saves 16

resistors compared to standard HCSL outputs

? 53mW typical power consumption in PLL mode; minimal

power consumption

? Spread Spectrum (SS) compatible; allows use of SS for

EMI reduction

? OE# pins; support DIF power management

? HCSL compatible differential input; can be driven by

common clock sources

? 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

? Software selectable 50MHz or 125MHz PLL operation;

useful for Ethernet applications

? 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 32-VFQFPN; minimal board

space

? Selectable SMBus addresses; multiple devices can

easily share an SMBus segment
