RC19104A001GNL#BB0

Overview

The RC19104A001GNL#BB0 is a Renesas Electronics clock buffer designed for PCIe Gen7 applications. It operates on a single 1.8V supply and provides four differential outputs. The device features ultra-low additive phase jitter, specified at 2.6fs RMS for PCIe Gen7 compliance. It supports flexible start-up timing, automatic clock holdover upon loss of the input clock, and spread-spectrum tolerance. The component accepts HCSL or LVDS input signals and offers selectable differential output impedances of 33Ω, 85Ω, or 100Ω via pin or SMBus configuration.

Feature Summary

• Four differential LP-HCSL outputs with selectable impedance (33Ω, 85Ω, 100Ω)
• Ultra-low additive phase jitter: 2.6fs RMS for PCIe Gen7
• Supports HCSL or LVDS input signal levels
• Features flexible start-up timing and automatic clock holdover

Applications

• PCIe Gen7 system clock distribution
• High-speed server and storage backplane designs
• Data center infrastructure requiring low-jitter clocking

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the relevant environmental files provided by Renesas Electronics. Ensure the selected variant matches the required output impedance settings for the target PCB design.

Selection Notes

Select this component when designing for PCIe Gen7 standards requiring minimal added jitter. Verify that the 1.8V supply voltage aligns with the system power architecture. Check if the 28-VFQFPN package dimensions fit the available board space. Confirm compatibility with HCSL or LVDS source drivers before finalizing the design.

Part Context

This part belongs to the RC191xx series of 1.8V PCIe Gen7 buffers. It serves as a fanout buffer to distribute reference clocks to multiple downstream components. The series is characterized by backward compatibility with earlier PCIe generations while optimizing performance for next-generation high-speed serial links.
