Block Diagram
Features/Benefits
⢠LP-HCSL outputs with Zo=100ï; 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
