RENESAS 9DBU0841AKLFT

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

• 8 – 1-167MHz Low-Power (LP) HCSL DIF pairs w/Z0=100Ω
• DIF cycle-to-cycle jitter <50ps
• DIF output-to-output skew <80ps
• DIF phase jitter is PCIe Gen1-2-3 compliant
• Very low additive phase jitter in bypass mode
• Direct connection to 100Ω 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 space

• 1.5V PCIe Gen1-2-3 Zero Delay/Fanout Buffer (ZDB/FOB)
