Features
- Direct connection to 100Ω transmission lines; saves 24 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 1.05V 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 are 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 5mm x 5mm 40-pin VFQFPN; minimal board space
- 3 selectable SMBus addresses; multiple devices can easily share an SMBus segment
Description
The 9DBV0641 6-output 1.8V PCIe fanout clock buffer is a member of Renesas' very-low power PCIe family. It has integrated output terminations providing Zo = 100Ω for direct connection to 100Ω transmission lines. The device has six output enable pins for clock management and three selectable SMBus addresses.
