SN65LVEP11DGKR

Clock Buffers, Drivers Overview

The SN65LVEP11DGKR is a low-voltage positive emitter-coupled logic (LVPECL) clock buffer manufactured by Texas Instruments. It functions as a 1:2 fanout buffer designed for high-speed digital applications. The device operates with a supply voltage range of 2.375V to 3.8V and supports maximum clock frequencies up to 3.8 GHz. It features differential inputs and outputs, ensuring low skew performance suitable for precise timing requirements. The component is housed in an 8-SOIC package with a width of 3.90mm and is rated for operation within a temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports data rates up to 3.8 GHz
• Differential input and output configuration
• Operates on a single 2.375V to 3.8V supply
• Available in an 8-SOIC surface-mount package

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Point-to-point or point-to-multipoint LVPECL signaling
• Telecommunications equipment requiring low-skew buffering

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'DGKR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the specific revision level matches the design specifications, as manufacturing updates may occur without functional changes. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended to differential or differential-to-differential LVPECL fanout is required at frequencies approaching 3.8 GHz. The 1:2 ratio makes it suitable for splitting a master clock signal to two downstream loads. Consider the 8-SOIC footprint constraints during PCB layout to ensure adequate thermal dissipation and signal integrity at high speeds.

Clock Buffers, Drivers Part Context

This part belongs to the SN65LVEP11 family of LVPECL buffers. The base model SN65LVEP11 denotes the core functionality, while the suffix 'DGK' specifies the 8-SOIC package type. The final 'R' indicates reel packaging. Other variants in the series may offer different pin counts or packaging options such as VSSOP or SOIC-16.

Clock Buffers, Drivers Replacement Considerations

The SN65LVEP11DGK serves as the tube-packaged equivalent of this component. For direct substitution, verify that the package dimensions and pinout are identical. Alternative devices from other manufacturers must match the LVPECL electrical characteristics and 3.8 GHz frequency limit.
