RC19204AGNL#KB0

Overview

The RC19204AGNL#KB0 is a single-circuit clock buffer from Renesas Electronics, designed for PCI Express applications. It accepts HCSL or LVDS differential inputs and provides four LP-HCSL differential outputs with a 2:04 input-to-output ratio. The device operates within a supply voltage range of 2.97V to 3.63V and supports frequencies up to 400MHz. It is housed in a 28-VFQFPN (4x4 mm) package with an exposed pad, suitable for surface mount assembly. The component functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Single circuit configuration with 2:04 input-to-output ratio
• Supports HCSL and LVDS differential inputs
• Generates four LP-HCSL differential outputs
• Maximum frequency operation of 400MHz

Applications

• PCI Express (PCIe) clock distribution systems

Procurement Notes

Verify the specific ordering suffix #KB0 against official Renesas documentation to confirm packaging details such as tape and reel specifications. Ensure the selected variant matches the required 28-VFQFPN package dimensions and thermal pad requirements for proper PCB integration.

Selection Notes

Select this component when a single-input, four-output clock buffer is required for PCIe designs. Confirm that the system power supply falls within the 2.97V to 3.63V range. Verify compatibility between the source signal type (HCSL or LVDS) and the available input options on this specific part number.

Part Context

This model belongs to Renesas' application-specific clock and timing product line. It is engineered specifically to meet the jitter and signal integrity requirements of high-speed serial interfaces like PCI Express, providing necessary fan-out capabilities for multi-lane architectures.

Replacement Considerations

Consult official Renesas cross-reference tools for verified substitutes. Ensure any replacement maintains the 28-VFQFPN footprint, 400MHz maximum frequency, and compatible input/output voltage levels.
