RC19202AGNT#KD0

Overview

The RC19202AGNT#KD0 is a PCIe Gen7 2:2 clock multiplexer from Renesas Electronics, designed for high-speed serial link applications. It supports input frequencies up to 400 MHz with LP-HCSL differential outputs. The device operates on a 3.3V supply (2.97V–3.63V) and features ultra-low additive jitter of 37 fs RMS typical. Key architectural features include flexible power sequencing, loss-of-signal indication, and automatic clock parking. It is housed in a compact 3.0 x 3.0 mm 20-VFQFPN package with a 0.4 mm pitch, suitable for dense PCB layouts.

Feature Summary

• PCIe Gen1 through Gen7 compliance with backward compatibility
• Ultra-low additive jitter performance (37 fs RMS typical)
• Flexible power sequencing and automatic clock parking capabilities
• Open-drain Loss-Of-Signal (LOS) indicator output

Applications

• PCI Express Gen7 interconnects
• High-performance server backplanes
• Storage area networks (SAN)
• Data center infrastructure

Procurement Notes

Verify the specific suffix #KD0 against official Renesas documentation to confirm packaging details, as local sources may list conflicting package types such as TSSOP or VFQFPN. Ensure the ordering code matches the required tape-and-reel configuration if applicable. Cross-reference the manufacturer part number directly with the datasheet to avoid substitution errors due to minor suffix variations.

Selection Notes

Select this component for designs requiring strict PCIe Gen7 timing margins and low jitter budgets. The 2:2 mux architecture allows for redundant clock source selection. Verify that the system design accommodates the 3.3V core voltage requirement and the thermal characteristics of the exposed pad VFQFPN package for adequate heat dissipation during operation.

Part Context

This part belongs to the RC192xx family of clock multiplexers, specifically engineered for next-generation PCIe standards. It serves as a critical timing element in systems demanding high reliability and signal integrity. The device integrates advanced features like power-down tolerance and SMBus write protection to simplify system integration and enhance operational robustness compared to previous generation components.
