8T39S08ANLGI

Clock Buffers, Drivers Overview

The 8T39S08ANLGI is a high-performance clock fanout buffer and multiplexer manufactured by Renesas Electronics. It features a 3:8 input-to-output ratio with differential inputs and outputs, supporting maximum frequencies of 2 GHz for LVPECL and LVDS signals. The device accepts HCSL, HSTL, LVDS, LVPECL, or crystal inputs and operates on a supply voltage range of 2.375V to 3.465V. Designed for surface mount applications, it is housed in a 40-VFQFPN package with an exposed pad and functions within an ambient temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports differential inputs (HCSL, HSTL, LVDS, LVPECL) and crystal oscillator interfaces
• Provides eight configurable differential outputs (LVPECL, LVDS, HCSL) with a maximum frequency of 2 GHz
• Integrated multiplexer functionality allows selection between two differential input pairs or one crystal input
• Operates from a single supply voltage range of 2.375V to 3.465V

Clock Buffers, Drivers Applications

• High-frequency clock distribution networks
• Low phase-noise signal fanout for data converters
• System timing architectures requiring multiple clock domains

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors prior to procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 3:8 fanout ratio with differential signaling is required. Ensure the system design supports the specified 2.375V to 3.465V supply voltage range. Verify that the 40-VFQFPN package dimensions align with the PCB layout constraints and thermal management requirements.

Clock Buffers, Drivers Part Context

This part belongs to the 8T39S series of clock buffers and multiplexers. It is functionally related to other variants such as the 8T39S10NLGI and 8T39S11A, which offer different output counts and pin configurations while sharing similar core performance characteristics and interface capabilities.

Clock Buffers, Drivers Replacement Considerations

Direct replacements include the 8T39S10NLGI and 8T39S11A. Verify pin compatibility and output configuration differences before substitution.
