RC19016AGN1#BB0

Overview

The RC19016AGN1#BB0 is a PCIe Gen7 compliant clock buffer manufactured by Renesas Electronics. It features one differential input and sixteen LP-HCSL differential outputs, providing a 1:16 fanout ratio. The device supports input frequencies up to 400 MHz with a maximum propagation delay of 1.8 ns. It operates on a single 3.3 V supply (2.97V to 3.63V) within an industrial temperature range of -40°C to +105°C. Packaged in a 64-pin VFQFPN (9x9 mm), it includes 85 Ω output impedance and SMBus control capabilities.

Feature Summary

• PCIe Gen7 compliance with backward compatibility for earlier generations
• Ultra-low additive jitter and reduced in-to-out delay performance
• LP-HCSL outputs eliminate up to 64 terminated resistors
• SMBus interface for selectable output slew rate and write protection

Applications

• PCIe Gen7 infrastructure systems
• High-performance computing platforms
• Server and storage controller timing distribution

Procurement Notes

Verify the specific ordering suffix #BB0 against the manufacturer's current datasheet to confirm package type and moisture sensitivity level. Ensure the design accounts for the 64-VFQFPN exposed pad thermal requirements and the 3.3 V power supply tolerance limits specified in the official documentation.

Selection Notes

Select this component when a 16-channel fanout buffer is required for PCIe Gen7 applications. It is suitable for designs needing LP-HCSL signaling to reduce termination resistor count. Compare against other RC190xxA variants if different output counts or impedance options are needed.

Part Context

This part belongs to the RC190xxA family of PCIe Gen7 clock buffers. It shares architectural similarities with models like the RC19008 and RC19020 but provides a specific 16-output configuration. The family is designed for robust clock distribution in high-speed serial interfaces.

Replacement Considerations

Direct pin-compatible replacements within the same family include the RC19016AGN1#BD0. Verify functional equivalence and package dimensions before substitution.
