Features/Benefits

• Direct connection to 100 (xx41) or 85 (xx51)

transmission lines; saves 28 resistors compared to

standard PCIe devices

• 134mW typical power consumption; eliminate thermal

concerns

• VDDIO allows 50 power savings at optional 1.05V;

maximum power savings

• SMBus-selectable features allows optimization to customer

requirements:

– control input polarity

– control input pull up/downs

– slew rate for each output

– differential output amplitude

– output impedance for each output

• Customer defined SMBus power up default can be

programmed into P1 device; allows exact optimization to

customer requirements

• OE# pins; support DIF power management

• HCSL differential input; can be driven by common clock sources

• Spread Spectrum tolerant; allows reduction of EMI

• Device contains default configuration; SMBus interface not

required for device operation

• Three selectable SMBus addresses; multiple devices can

easily share an SMBus segment

• Space saving 40-pin 5 x 5mm VFQFPN; minimal board space
