RC19024AGNQ#BB0

Overview

The RC19024AGNQ#BB0 is a PCIe Gen6 fanout buffer manufactured by Renesas Electronics. It features one differential input and twenty-four LP-HCSL outputs, supporting frequencies up to 400 MHz. The device operates within a supply voltage range of 2.97 V to 3.63 V and functions at temperatures between -40°C and +105°C. Packaged in a 100-VFQFPN (8x8 mm) surface-mount case with an exposed pad, it provides high-speed clock distribution for PCI Express applications.

Feature Summary

• Supports 24 LP-HCSL outputs for high-density clock distribution
• Compatible with HCSL and LVDS differential inputs
• Operates at maximum frequency of 400 MHz
• Designed for PCIe Gen6 compliance

Applications

• PCI Express Gen6 system clock distribution
• High-performance server and storage backplanes
• Network infrastructure equipment requiring low-jitter clocking

Procurement Notes

Verify the package designation matches the 100-VFQFPN (8x8 mm) specification. Confirm the operating temperature range covers the required -40°C to +105°C application environment. Ensure the supply voltage aligns with the 2.97 V to 3.63 V limits. Check for specific RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when a single differential clock source must drive twenty-four loads. Verify that the load requirements match the LP-HCSL output signaling standard. Ensure the PCB layout supports the 8x8 mm QFN package thermal dissipation needs. Compare against other Renesas RC190xxA series parts if fewer outputs are sufficient.

Part Context

This part belongs to the RC19024A family of PCIe fanout buffers. It serves as a timing solution for systems requiring extensive clock branching. The device replaces discrete buffering solutions with a single integrated circuit. It is designed to meet the stringent jitter and skew requirements of modern high-speed serial interfaces.

Replacement Considerations

Check for pin-compatible alternatives within the RC190xxA series. Verify electrical parameters such as output current and propagation delay against existing designs. Ensure the replacement package matches the 100-VFQFPN footprint.
