9DBV0631数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

描述 Description

The 9DBV0631 is a member of IDT's 1.8V Very-Low-Power (VLP) PCIe family. The device has 6 output enables for clock management and 3 selectable SMBus addresses.

特性 Features

• LP-HCSL outputs; save 12 resistors compared to standard PCIe devices
• 55 mW typical power consumption in PLL mode; minimal power consumption
• Outputs can optionally be supplied from any voltage between 1.05 and 1.8 V; 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
• 3.3 V tolerant SMBus interface  works with legacy controllers
• Space saving 5x5 mm 40-pin VFQFPN; minimal board space
• 3 selectable SMBus addresses; multiple devices can easily share an SMBus segment
