8SLVP1208ANBGI/W

Clock Buffers, Drivers Overview

The 8SLVP1208 is a high-performance differential LVPECL fanout buffer designed for distributing high-frequency, low-additive phase-noise clock and data signals. It features two selectable differential input pairs and eight low-skew output pairs. The device supports LVDS, LVPECL, and CML input levels with a maximum frequency of 2GHz. It operates on full 3.3V or 2.5V supplies, consuming a maximum current of 141mA. Key electrical parameters include a typical output skew of 28ps, a maximum propagation delay of 410ps, and a maximum RMS additive phase jitter of 54.1fs at 156.25MHz.

Clock Buffers, Drivers Procurement Notes

Renesas Electronics Corporation's timing product line has been acquired by SiTime. Data sheets and ordering remain available via Renesas.com until the end of 2026. New designs, procurement, and technical support should be directed to SiTime. Verify current availability and transition status directly with the manufacturer or authorized distributors before finalizing orders.

Clock Buffers, Drivers Selection Notes

Select this component when an LVPECL fanout buffer with eight outputs is required. Ensure the design accommodates the 28-lead VFQFN package and the -40°C to 85°C operating temperature range. Verify that the system power supply matches the 3.3V or 2.5V requirements and that the input signal levels are compatible with the selectable differential inputs.

Clock Buffers, Drivers Part Context

The 8SLVP1208 belongs to the 8SLVP series of LVPECL fanout buffers from Renesas. This series includes variants with different output counts, such as the 8SLVP1204 (4 outputs) and 8SLVP1212I (12 outputs). These devices share similar architectural features, including low additive jitter and selectable differential inputs, tailored for various clock distribution densities.

Clock Buffers, Drivers Replacement Considerations

Due to the acquisition of Renesas' timing products by SiTime, verify if SiTime offers equivalent LVPECL fanout buffers with matching pinouts and specifications. Check for direct cross-reference part numbers provided by SiTime or Renesas for seamless integration into existing designs.
