8SLVD1204-33NLGI

Clock Buffers, Drivers Overview

The 8SLVD1204-33NLGI 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, it operates from a 3.3V or 2.5V power supply. The device features two selectable differential clock input pairs and four low-skew, low additive jitter LVPECL output pairs. It supports PCI Express Gen 1–5 standards and accepts various differential input levels including LVDS, LVPECL, and CML. Key electrical parameters include a maximum input clock frequency of 2GHz, typical output skew of 5ps, and maximum propagation delay of 320ps.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix '33NLGI' against official Renesas documentation to confirm package type, lead finish, and temperature range specifications. Ensure compatibility with 3.3V or 2.5V supply requirements and check for RoHS compliance status in the latest datasheet.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and low additive jitter are critical for PCI Express or similar high-speed serial link applications. Confirm that the LVPECL output swing matches downstream receiver inputs. Verify that the 2GHz maximum input frequency meets system clock requirements.

Clock Buffers, Drivers Part Context

The 8SLVD1204 belongs to the 8SLVP series of differential LVPECL fanout buffers. This series is characterized by guaranteed output-to-output and part-to-part skew, making it suitable for applications demanding well-defined performance and repeatability in clock distribution networks.

Clock Buffers, Drivers Replacement Considerations

Consult Renesas official substitution guides for compatible devices within the 8SLVP family. Verify pinout compatibility and electrical parameter equivalence before replacing the original component.
