8P34S1204NLGI8

Clock Buffers, Drivers Overview

The 8P34S1204NLGI8 is a high-performance differential LVDS fanout buffer manufactured by Renesas Electronics. It features a 2:4 input-to-output ratio, supporting two selectable differential clock inputs and four low-skew LVDS outputs. The device operates with supply voltages of 1.71V to 1.89V or 2.1V to 2.7V, accommodating both 1.8V and 2.5V logic levels. It supports maximum input frequencies up to 1.2 GHz in this specific package variant, with typical output skew of 10ps and maximum propagation delay of 400ps. Packaged in a 16-VFQFN (3x3mm) with exposed pad, it is designed for applications requiring low additive phase noise and precise clock distribution.

Clock Buffers, Drivers Feature Summary

• 2:4 Fanout Ratio: Two selectable differential inputs drive four low-skew LVDS outputs.
• Low Skew and Jitter: Typical output skew of 10ps and RMS additive phase jitter of 34fs (at 156.25MHz reference).
• Dual Voltage Operation: Supports 1.8V (1.71V–1.89V) and 2.5V (2.1V–2.7V) power supplies.
• Compact Package: Available in a 16-lead VFQFPN (3x3mm) surface-mount package.

Clock Buffers, Drivers Applications

• PCI Express Gen 1-5 Clock Distribution
• High-Speed Data Signal Fanout
• 1PPS Signal Distribution

Clock Buffers, Drivers Procurement Notes

Verify the suffix 'I8' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging option distinct from the standard tray-packaged 'NLGI'. Ensure compatibility with moisture sensitivity level (MSL 3) handling requirements during assembly.

Clock Buffers, Drivers Selection Notes

Select the 8P34S1204NLGI8 when a 2:4 LVDS fanout buffer is required with strict skew constraints. Compare against the 8P34S1212 for higher output counts or the 8SLVP1204 for LVPECL outputs. Confirm that the 1.2 GHz frequency rating meets system timing requirements.

Clock Buffers, Drivers Part Context

This component belongs to the 8P34S1204 family of clock buffers. It shares core specifications with variants like the 8P34S1204NLGI but may differ in packaging configuration or secondary ordering codes. It is part of Renesas' portfolio for high-speed clock distribution solutions.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible substitutes within the same family include the 8P34S1204NLGI. For different output counts, consider the 8P34S1212 (1:12) or 8P34S2108 (1:8). Verify electrical parameters match before substitution.
