RC19008AGND#BB0

Overview

The RC19008AGND#BB0 is a PCIe clock buffer manufactured by Renesas Electronics Corporation, designed for high-speed data transmission applications. It operates within a supply voltage range of 2.97V to 3.63V and supports input signals in HCSL or LVDS formats. The device provides eight differential outputs in HCSL or LVDS configurations, maintaining a 1:8 input-to-output ratio. With a maximum operating frequency of 400MHz, it ensures signal integrity across an extended temperature range of -40°C to +105°C. The component is housed in a 40-VFQFPN package with dimensions of 5mm x 5mm, suitable for surface mount assembly.

Feature Summary

• Supports 1:8 buffering ratio with differential HCSL or LVDS inputs and outputs
• Operates at frequencies up to 400MHz with a supply voltage of 2.97V to 3.63V
• Available in a compact 40-VFQFPN (5x5) exposed pad package

Applications

• PCI Express (PCIe) timing systems
• High-speed server and storage infrastructure
• Network equipment requiring precise clock distribution

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and moisture sensitivity level. Confirm that the 40-VFQFPN package matches the design requirements for thermal dissipation and board space constraints. Ensure compliance with RoHS directives as indicated in official datasheets before finalizing procurement orders.

Selection Notes

Select this component when a single differential clock source needs to drive eight downstream loads with minimal skew. Verify that the system power supply remains stable between 2.97V and 3.63V. Consider the 40-VFQFPN footprint during PCB layout to ensure adequate clearance for the exposed pad thermal connection.

Part Context

This part belongs to the Renesas clock buffer family tailored for PCIe standards. It serves as a critical timing element in complex digital systems where signal fidelity and low jitter are paramount. The device replaces older buffering solutions by offering higher density and improved performance characteristics within a standardized package form factor.

Replacement Considerations

Consult the official Renesas cross-reference guide for verified pin-compatible alternatives. Ensure any substitute maintains the same 40-VFQFPN package and electrical specifications to avoid redesigning the host circuit board.
