RC19020AGN6#BD0

Overview

The RC19020AGN6#BD0 is a PCIe Gen7 compliant clock buffer manufactured by Renesas Electronics. It features one differential input and twenty LP-HCSL differential 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 across an industrial temperature range of -40°C to +105°C. Packaged in an 80-GQFN (6x6 mm) surface-mount case with an exposed pad, it provides ultra-low additive jitter and reduced in-to-out delay performance for robust high-speed serial design margins.

Feature Summary

• PCIe Gen1–Gen7 compliance with backward compatibility
• 20 LP-HCSL differential outputs eliminating up to 80 terminated resistors
• Supports both source-terminated and double-terminated loads
• Integrated open-drain Loss-Of-Signal (LOS) indication output

Applications

• PCI Express Gen7 endpoint and switch clock distribution
• High-performance computing server backplanes
• Data center infrastructure timing systems

Procurement Notes

Verify the specific ordering suffix #BD0 against the manufacturer's official datasheet to confirm tray packaging and moisture sensitivity level requirements. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the full part number to distinguish between tape-and-reel and tray variants within the RC19020A family.

Selection Notes

Select this component when designing for PCIe Gen7 or earlier generations requiring 20 fanout channels. Verify that the system power supply remains stable between 2.97 V and 3.63 V. Confirm that the PCB layout accommodates the 6mm x 6mm 80-GQFN package dimensions and thermal pad requirements for proper heat dissipation during operation.

Part Context

This part belongs to the RC190xxA series of PCIe clock buffers. It serves as a pin-compatible upgrade to the DB2000QL, adding Loss-Of-Signal indication and Side-Band Interface (SBI_OUT) capabilities for daisy-chaining multiple clock chips. It shares functional similarities with other members like the RC19008 and RC19016 but offers higher output density.

Replacement Considerations

The RC19020A072GN2#BB0 is a compatible alternative within the same family, offering identical electrical specifications but differing in packaging format (tape-and-reel vs. tray). Other pin-compatible options include the DB2000QL for legacy designs lacking LOS functionality.
