特性
- 1.8V operation: 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
- LP-HCSL differential clock outputs: reduced power and board space
- 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 6 x 6 mm 48-VFQFPN: minimal board space
- Selectable SMBus addresses: multiple devices can easily share an SMBus segment
描述
The 9DBV0831 is an 8-output very low power buffer for 100MHz PCIe Gen1–5 applications. It can also be used for 50M or 125M Ethernet Applications via software frequency selection. The device has 8 output enables for clock management, and 3 selectable SMBus addresses.
