8P34S1204NLGI

Clock Buffers, Drivers Overview

The 8P34S1204NLGI is a high-performance differential LVDS fanout buffer manufactured by Renesas Electronics Corporation. It features a 2:4 input-to-output ratio, supporting two selectable differential clock inputs and four low-skew outputs. The device operates on dual supply voltages of 1.71V to 1.89V or 2.1V to 2.7V. Key electrical parameters include a maximum input frequency of 1.2 GHz, typical output skew of 10 ps, and maximum propagation delay of 400 ps. It is housed in a 16-VFQFN package with exposed pad.

Clock Buffers, Drivers Feature Summary

• Supports differential input levels including LVDS and CML for flexible interfacing
• Low additive phase jitter (typical 34 fs RMS at 156.25 MHz reference)
• Integrated bias voltage reference enables single-ended signal interfacing
• Fail-safe operation ensures defined output states during input loss

Clock Buffers, Drivers Applications

• Fanout of 1PPS signals
• High-frequency clock distribution
• PCI Express Gen 1-5 systems

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'NLGI' against the manufacturer datasheet to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for any product change notifications regarding label changes or final test locations.

Clock Buffers, Drivers Selection Notes

Select this component when a 2:4 LVDS fanout buffer is required for frequencies up to 1.2 GHz. Ensure the design supports the specified 1.8V or 2.5V supply rails. Consider the 16-VFQFPN package dimensions (3x3 mm) for PCB layout constraints compared to other packages in the 8P34S family.

Clock Buffers, Drivers Part Context

This part belongs to the 8P34S1204 series from Renesas. It is distinct from similar parts like the 8P34S1212 (1:12 ratio) or 8P34S1102 (1:2 ratio). The NLGI suffix indicates the specific tape and reel or tray packaging configuration provided by distributors.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible replacements within the same family include the 8P34S1204I variant. Verify if alternative packages such as VFQFPN are acceptable substitutes if the specific 'NLGI' packaging differs from available inventory.
