8V79S683NLGI

Clock Buffers, Drivers Overview

The Renesas 8V79S683NLGI is a high-performance clock buffer and divider designed for JESD204B applications. It features a 2:16 differential input-to-output ratio, supporting frequencies up to 3 GHz. The device provides four output channels with configurable LVDS or LVPECL outputs. It operates on a single 3.3V supply (3.135V–3.465V) and includes integrated dividers and phase delay circuits. Packaged in a 64-VFQFN exposed pad (9x9 mm), it supports surface mount assembly and functions within an operating temperature range of -40°C to +105°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'NLGI' against the manufacturer's official datasheet to confirm package type, moisture sensitivity level, and lead finish specifications. Ensure compatibility with the required operating temperature range (-40°C to +105°C) for the target application environment before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 2:16 fanout ratio with integrated division capabilities is required for high-frequency clock distribution. Confirm that the system design accommodates the 64-VFQFN package dimensions and thermal requirements. Verify that the 3.3V supply voltage aligns with the system power architecture.

Clock Buffers, Drivers Part Context

This part belongs to the 8V79S680 series of clock buffers and dividers. It is specifically optimized for distributing clock and SYSREF signals in JESD204B applications, providing deterministic latency and phase alignment across multiple channels.

Clock Buffers, Drivers Replacement Considerations

Consult the manufacturer's official replacement guide for verified cross-references. Generic equivalents may not support the specific 2:16 ratio or integrated divider functionality required for JESD204B compliance.
