特性
- LP-HCSL outputs with Zo=100Ω; saves 8 resistors compared to standard HCSL output
- 35mW typical power consumption in PLL mode; minimal power consumption
- Spread Spectrum (SS) compatible; allows use of SS for EMI reduction
- OE# pins; support DIF power management
- HCSL compatible differential input; can be driven by common clock sources
- SMBus-selectable features; optimize signal integrity to application
- slew rate for each output
- differential output amplitude
- Pin/software selectable PLL bandwidth and PLL Bypass; optimize PLL to application
- Outputs blocked until PLL is locked; clean system start-up
- Device contains default configuration; SMBus interface not required for device control
- 3.3V tolerant SMBus interface; works with legacy controllers
- Space saving 24-pin 4x4mm VFQFPN; minimal board space
描述
