SN65LVEL11DR

Clock Buffers, Drivers Overview

The SN65LVEL11DR is a high-speed clock buffer manufactured by Texas Instruments, designed for PECL and ECL signal distribution. It features a 1:2 fanout configuration with differential inputs and outputs. The device supports maximum input frequencies up to 3.8 GHz and operates within a supply voltage range of 2.375 V to 3.8 V. Key electrical parameters include a maximum propagation delay of 300 ps and a typical operating 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 PECL and ECL input/output signaling standards
• Maximum operating frequency of 3.8 GHz
• Low propagation delay of 300 ps (maximum)
• Single-channel 1:2 fanout buffer architecture

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• PECL/ECL signal buffering and fan-out
• Telecommunications equipment requiring low skew timing
• Test and measurement instrumentation

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when ordering. Confirm that the required quantity aligns with the manufacturer's standard reel size to avoid cut-tape premiums or minimum order constraints. Ensure the design accommodates the 8-SOIC footprint dimensions and thermal requirements specified in the mechanical outline drawing.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended or differential PECL/ECL source must drive two downstream loads with minimal skew. Compare against the SN65LVEP11D if tube packaging is preferred over reels. Verify that the system power supply can maintain stability within the 2.375 V to 3.8 V range to ensure proper logic threshold operation at 3.8 GHz speeds.

Clock Buffers, Drivers Part Context

This part belongs to the SN65LV series of low-voltage PECL/ECL buffers from Texas Instruments. It serves as a direct replacement for older discrete transistor solutions in high-frequency clocking applications. The 'DR' suffix specifically denotes the reel packaging variant, distinct from the 'D' tube version, while maintaining identical electrical characteristics and pinout compatibility.

Clock Buffers, Drivers Replacement Considerations

The SN65LVEP11D is a functional equivalent with identical electrical specifications but differs in packaging (tube vs. reel). Cross-reference with MC100LVEP11DG from onsemi for alternative sourcing, noting potential differences in pinout or supply voltage tolerances.
