RC19204AGNL#BB0

Overview

The RC19204AGNL#BB0 is a PCIe Gen7 clock multiplexer manufactured by Renesas Electronics. It provides a 2:4 input-to-output ratio with differential LVDS or HCSL inputs and LP-HCSL outputs. The device supports frequencies up to 400MHz and operates on a single supply voltage ranging from 2.97V to 3.63V. Designed for high-performance timing applications, it features ultra-low additive jitter and reduced in-to-out delay performance. The component is housed in a 28-VFQFPN package (4x4mm) with an exposed pad, suitable for surface mount assembly across an operating temperature range of -40°C to +105°C.

Feature Summary

• PCIe Gen7 compliant 2:4 clock multiplexer backward compatible with earlier generations
• Ultra-low additive jitter and reduced in-to-out delay for improved design margin
• Supports differential LVDS and HCSL inputs with LP-HCSL outputs
• Flexible startup sequencing and power down tolerance for robust system integration

Applications

• AMD Fourth Generation EPYC (Genoa) power and timing systems
• Server platforms supporting SVI3, DDR5, and PCIe Gen 5/6 interfaces
• High-speed serial communication infrastructure requiring precise clock distribution

Procurement Notes

Verify the specific ordering suffix #BB0 against official Renesas documentation to confirm tape-and-reel packaging details. Confirm moisture sensitivity level and reflow soldering profiles prior to procurement. Ensure compatibility with existing board designs regarding the 28-VFQFPN footprint and thermal requirements.

Selection Notes
