The 9DBU0431 is a member of IDT's 1.5 V Ultra-Low-Power (ULP) PCIe family. The device has 4 output enables for clock management, and 3 selectable SMBus addresses.
Features
- LP-HCSL outputs; save 8 resistors compared to standard HCSL outputs
- 45 mW typical power consumption in PLL mode; minimal power consumption
- 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
- 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 32-pin 5x5mm VFQFPN; minimal board space
- 3 selectable SMBus addresses; multiple devices can easily share an SMBus segment
