SN65LVEP11D

Clock Buffers, Drivers Overview

The SN65LVEP11D is a single-channel clock buffer and fanout driver manufactured by Texas Instruments. It accepts PECL or ECL differential inputs and provides four complementary ECL/PECL outputs, achieving a 1:4 fanout ratio. The device operates within a supply voltage range of 2.375 V to 3.8 V and supports maximum input frequencies up to 3.8 GHz. Key electrical specifications include a maximum propagation delay of 300 ps and a typical operating supply current of 45 mA. It is housed in an 8-SOIC surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports both PECL and ECL input logic levels with corresponding output drivers
• Provides 1:4 fanout capability with four differential outputs from a single input
• Maximum operating frequency of 3.8 GHz with propagation delay under 300 ps
• Operates on a single 3.3 V supply (2.375 V to 3.8 V range) with 45 mA quiescent current

Clock Buffers, Drivers Applications

• High-speed clock distribution networks requiring low skew
• PECL/ECL signal buffering in telecommunications infrastructure
• Fanout buffering for high-frequency oscillator signals
• Test and measurement equipment requiring precise timing distribution

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for active production status and lead times directly with authorized distributors, as availability fluctuates. Ensure ordering quantities align with standard tube packaging configurations provided by the manufacturer.

Clock Buffers, Drivers Selection Notes

Select this component when interfacing between PECL/ECL sources and downstream logic requiring multiple buffered copies. The 3.8 GHz bandwidth suits applications exceeding standard LVDS speeds where lower jitter is critical compared to other translators. Verify that the 3.3 V supply rail matches the system design, as the device does not support higher voltage ECL standards like -5V without level shifting.

Clock Buffers, Drivers Part Context

This part belongs to the SN65LVEP11 family of high-speed clock buffers. It serves as a specialized solution for maintaining signal integrity in high-frequency digital systems. Unlike general-purpose logic buffers, it is optimized specifically for the voltage swings and termination requirements of PECL and ECL standards.

Clock Buffers, Drivers Replacement Considerations

Consult the Texas Instruments SN65LVEP11 datasheet for direct pin-compatible alternatives within the same series. Verify that any substitute maintains the 3.8 GHz frequency rating and 1:4 fanout configuration to ensure circuit compatibility.
