9DBV0831中文资料8-Output 1.8V PCIe Zero-Delay/Fanout Clock Buffer数据手册Renesas规格书

描述 Description

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.

特性 Features

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
