8SLVP1204ANLGI/W

Clock Buffers, Drivers Overview

The 8SLVP1204ANLGI/W is a high-performance differential LVPECL fanout buffer manufactured by Renesas Electronics. It supports two selectable differential clock input pairs and provides four low-skew, low additive jitter LVPECL output pairs. The device accepts differential input levels including LVDS, LVPECL, and CML, with a maximum input clock frequency of 2 GHz. It operates on full 3.3V or 2.5V supply voltages and features an LVCMOS interface for control inputs. Typical output skew is 5 ps, with a maximum propagation delay of 320 ps.

Clock Buffers, Drivers Feature Summary

• Four low-skew, low additive jitter LVPECL output pairs
• Two selectable differential clock input pairs (LVDS, LVPECL, CML)
• Maximum input clock frequency of 2 GHz
• Low additive phase jitter: 40 fs max (RMS, fREF = 156.25 MHz)

Clock Buffers, Drivers Applications

• Fanout of high-frequency, very-low additive phase-noise clock signals
• Clock distribution applications demanding well-defined performance and repeatability
• PCI Express Gen 1–5 support

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'W' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental rating, as standard listings often reference the NLGI package. Confirm current availability status, as timing products from this lineage may have transitioned to SiTime.

Clock Buffers, Drivers Selection Notes

Select this component when requiring a 2:4 LVPECL fanout buffer with low skew and jitter characteristics. Ensure the design utilizes a 3.3V or 2.5V supply. Verify that the input signal levels match the supported LVDS, LVPECL, or CML standards and that the required operating temperature range fits within -40 °C to 85 °C.

Clock Buffers, Drivers Part Context

This part belongs to the 8SLVP series of high-performance differential LVPECL fanout buffers. The product line has been acquired by SiTime, with documentation and samples remaining available via Renesas until the end of 2026. New designs are encouraged to consult SiTime for future sourcing.

Clock Buffers, Drivers Replacement Considerations

The 8SLVP1204ANLGI is listed as a similar replacement for the discontinued 85214AGLF.
