Features/Benefits
• Direct connection to 100 (xx41) or 85 (xx51)
transmission lines; saves 36 resistors compared to
standard PCIe devices
• 165mW typical power consumption (at 3.3V); eliminates
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 48-pin 6 x 6mm VFQFPN; minimal board space
