SN75DPHY440SSRHRT

Overview

The SN75DPHY440SSRHRT is a MIPI DPHY retimer designed for CSI-2 and DSI applications. It complies with the MIPI DPHY 1.1 specification and supports data rates up to 1.5 Gbps per lane. The device operates within a commercial temperature range of 0°C to 70°C. It features adjustable output voltage swing, selectable TX pre-emphasis, and configurable RX equalization to compensate for ISI loss. The component includes dynamic data and clock offset compensation and provides 3kV ESD HBM protection.

Feature Summary

• Supports MIPI DSI bidirectional LP mode and ULPS/LP power states
• Provides dynamic data and clock offset compensation
• Features configurable edge rate control and adjustable Rx EQ

Applications

• Laptops
• Tablets
• Cameras

Procurement Notes

Verify the specific suffix 'RTR' against official Texas Instruments documentation to confirm reel quantity and tape specifications. Ensure the commercial temperature grade (0°C to 70°C) matches system requirements rather than the industrial grade variant. Cross-reference the datasheet revision date to validate current manufacturing status and compliance details.

Selection Notes

Select this component when designing MIPI CSI-2 or DSI links requiring signal integrity restoration over cables. Compare against the SN65DPHY440SS series if an industrial temperature rating (-40°C to 85°C) is required instead of the commercial range. Confirm that the WQFN package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the SNx5DPHY440 family of MIPI DPHY retimers from Texas Instruments. It functions as a signal buffer and repeater specifically optimized for mobile and portable display interfaces. The device addresses signal degradation issues in high-speed MIPI connections by re-timing and reshaping data signals.

Replacement Considerations

SN65DPHY440SSRHRT serves as the industrial temperature rated alternative.
