RC19216AGN6#KD0

Overview

The RC19216AGN6#KD0 is a PCIe Gen7 2:16 clock multiplexer from Renesas Electronics. It accepts two differential inputs (LVDS or HCSL) and provides sixteen LP-HCSL outputs. The device operates within a frequency range of 1 MHz to 400 MHz on a 3.3V supply, with typical power consumption of 534 mW. It features ultra-low additive jitter (typical RMS 37 fs) and supports selectable 85Ω or 100Ω output impedance. Packaged in a 6mm × 6mm 80-GQFN, it includes SMBus control, LOS indication, and flexible startup sequencing for robust system design.

Feature Summary

• PCIe Gen1–Gen7 compliance with backward compatibility
• Ultra-low additive phase jitter (typical 37 fs RMS)
• LP-HCSL outputs eliminate up to 64 terminated resistors
• SMBus write protection with 9 selectable addresses

Applications

• PCI Express Gen7 clock distribution networks
• High-speed serial data transmission systems
• Server and storage infrastructure clocking

Procurement Notes

Verify the specific suffix (#KD0) against official documentation to confirm packaging details such as reel quantity and carrier type. Ensure the operating temperature range (-40°C to 105°C) aligns with the target application environment. Confirm that the 80-GQFN package dimensions match the PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 2:16 multiplexing ratio is required for PCIe Gen7 compliant designs. It is suitable for applications needing low jitter performance and LP-HCSL signaling to reduce board complexity. Consider the 85Ω/100Ω selectable impedance if driving mixed termination loads. Verify input signal compatibility with LVDS or HCSL sources.

Part Context

This part belongs to the RC19216A series of PCIe clock multiplexers. It shares core specifications with other variants like the RC19216AGN6#BD0, differing primarily in ordering suffixes which typically denote packaging or tape-and-reel configurations rather than functional changes.

Replacement Considerations

Direct pin-compatible replacements within the same family include the RC19216AGN6#BD0. Verify that any substitute maintains the 2:16 ratio, PCIe Gen7 compliance, and 80-GQFN package form factor.
