RC19208AGNA#KB0

Overview

The RC19208AGNA#KB0 is a PCIe Gen7 2:8 clock multiplexer manufactured by Renesas Electronics. It operates on a single 3.3V supply (2.97V to 3.63V) and accepts HCSL or LVDS differential inputs, providing eight LP-HCSL differential outputs. The device supports frequencies up to 400MHz with a typical power consumption of 250mW. It features ultra-low additive jitter and reduced input-to-output delay for improved design margins. The component is housed in a 48-VFQFPN package (6mm x 6mm) and functions within an operating temperature range of -40°C to +105°C.

Procurement Notes

Verify the specific ordering suffix #KB0 corresponds to the tape and reel packaging configuration as indicated in distributor listings. Confirm moisture sensitivity level (MSL 3) requirements for surface mount assembly processes. Ensure the 48-VFQFPN exposed pad thermal management aligns with the target PCB design specifications.

Selection Notes

Select this component when a PCIe Gen7 compliant clock distribution solution with low jitter is required. The 2:8 ratio allows for flexible clock routing from two sources to eight destinations. Verify that the system voltage falls within the 2.97V to 3.63V range and that the input signal type matches the supported HCSL or LVDS standards.
