8 O/P 1.5V PCIe Gen1-2-3 ZDB/FOB w/Zo=100ohms

Description
The 9DBU0841 is a member of IDTs 1.5V Ultra-Low-Power (ULP) PCIe family. It has integrated output terminations providing Zo=100 for direct connection to 100 transmission lines. The device has 8 output enables for clock management and 3 selectable SMBus addresses.

Features/Benefits
• Direct connection to 100 transmission lines; saves 32
   resistors compared to standard HCSL outputs
• 53mW typical power consumption in PLL mode; eliminates
   thermal concerns
• Outputs can optionally be supplied from any voltage
   between 1.05 and 1.5V; maximum power savings
• Spread Spectrum (SS) compatible; allows SS for EMI
   reduction
• OE# pins; support DIF power management
• HCSL-compatible differential input; can be driven by
   common clock sources
• Spread Spectrum tolerant; allows reduction of EMI
• SMBus-selectable features; optimize signal integrity to
   application
• slew rate for each output
• differential output amplitude
• Pin/SMBus 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
• Three selectable SMBus addresses; multiple devices can
   easily share an SMBus segment
• 3.3V tolerant SMBus interface works with legacy controllers
• Space saving 48-pin 6x6mm VFQFPN; minimal board
