Features/Benefits
• LP-HCSL outputs; save 14 resistors compared to standard
HCSL outputs
• 41mW typical power consumption; minimal power
consumption
• OE# pin for each output; support DIF power management
• HCSL 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
• 1MHz to 200MHz operating frequency
• 3.3V tolerant SMBus interface works with legacy controllers
• Selectable SMBus addresses; multiple devices can easily
share an SMBus segment
• Device contains default configuration; SMBus interface not
required for device operation
• Space saving 40-pin 5x5mm VFQFPN; minimal board
space
