8SLVD1204NLGI/W

Clock Buffers, Drivers Overview

The 8SLVD1204NLGI/W is a high-performance differential LVPECL fanout buffer manufactured by Renesas Electronics Corporation. Designed for the distribution of high-frequency, very-low additive phase-noise clock and data signals, this device supports PCI Express Gen 1 through Gen 5 standards. It features two selectable differential clock input pairs and four low-skew LVPECL output pairs. The component operates from a full 3.3V or 2.5V supply voltage and accepts various differential input levels including LVDS, LVPECL, and CML. Characterized for operation within an ambient temperature range of -40 °C to 85 °C, it ensures well-defined performance and repeatability in demanding clock distribution applications.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'NLGI/W' against official Renesas documentation to confirm package type, lead finish, and environmental compliance status such as RoHS 6. Ensure the ordering part number matches the exact electrical specifications and operating temperature range required for the target application design.

Clock Buffers, Drivers Selection Notes

Select this component when low additive phase noise and tight output-to-output skew are critical requirements. The device accommodates both 3.3V and 2.5V supply voltages, providing flexibility for different system power architectures. Verify that the input signal levels (LVDS, LVPECL, or CML) are compatible with the selected differential input pair configuration.

Clock Buffers, Drivers Part Context

The 8SLVD1204 belongs to the 8SLVP series of differential LVPECL fanout buffers. This family is engineered for applications demanding high-speed signal integrity and precise timing distribution. The device integrates an internal bias voltage reference to facilitate easy interfacing of single-ended signals if necessary, optimizing power consumption while maintaining low additive phase noise characteristics.

Clock Buffers, Drivers Replacement Considerations

Consult Renesas official cross-reference tools for verified substitutes. Ensure any replacement maintains compatibility with LVPECL outputs, supports the 2GHz maximum input frequency, and fits the 16-VFQFPN package constraints.
