RENESAS 9DB1933AKLF

The 9DB1933 zero-delay buffer supports PCIe Gen3 requirements, while being backwards compatible to PCIe Gen2 and Gen1. The 9DB1933 is driven by a differential SRC output pair from an IDT 932S421, 932SQ420, or equivalent, main clock generator. It attenuates jitter on the input clock and has a selectable PLL bandwidth to maximize performance in systems with or without Spread-Spectrum clocking.

• 8 Selectable SMBus Addresses/Mulitple devices can share the same SMBus Segment
• 11 dedicated and 3 group OE# pins/Hardware control of the outputs
• PLL or bypass mode/PLL can dejitter incoming clock
• Selectable PLL bandwidth/minimizes jitter peaking in downstream PLL's
• Spread Spectrum Compatible/tracks spreading input clock for low EMI
• SMBus Interface/unused outputs can be disabled
• Supports undriven differential outputs in Power Down mode for power management

• 19 output PCIe Gen3 zero-delay/fanout buffer
