SN75DPHY440SSRHRR

Overview

The SN75DPHY440SSRHRR is a MIPI DPHY retimer compliant with the MIPI D-PHY 1.1 specification, designed for CSI-2 and DSI applications. It supports data rates up to 1.5Gbps per lane and operates within a commercial temperature range of 0°C to 70°C. The device features adjustable output voltage swing, configurable TX pre-emphasis, and variable Rx equalization to compensate for ISI loss. It includes dynamic data and clock offset compensation, ULPS support, and 3kV ESD HBM protection. Packaged in a 28-WQFN (5.5x3.5mm) surface-mount format.

Feature Summary

• Supports MIPI DSI bidirectional LP mode and ULPS power states
• Provides dynamic data and clock offset compensation
• Features adjustable output voltage swing and configurable TX pre-emphasis
• Includes variable Rx equalization to compensate for channel loss

Applications

• Laptop computers
• Tablet devices
• Camera modules
• Flip-style mobile structures

Procurement Notes

Verify the specific suffix 'RHRR' against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure the commercial temperature grade (0°C to 70°C) aligns with system requirements, as the industrial variant uses a different part number. Cross-reference RoHS compliance status directly from the manufacturer's product information page before finalizing procurement.

Selection Notes

Select this component when designing MIPI CSI-2 or DSI links requiring signal integrity restoration over lossy cables. The SN75DPHY440SS is suitable for commercial environments; choose the SN65DPHY440SS if an extended industrial temperature range (-40°C to 85°C) is required. Consider the adjustable equalization and pre-emphasis features for optimizing eye diagrams in high-speed serial transmission scenarios.

Part Context

This device belongs to the SNx5DPHY440 family of MIPI retimers manufactured by Texas Instruments. It serves as a bridge between source and sink devices, enhancing signal quality for display and camera interfaces. The family distinguishes between commercial (SN75) and industrial (SN65) temperature grades while sharing identical functional pinouts and electrical characteristics.

Replacement Considerations

The SN65DPHY440SSRHRR is the direct industrial-grade equivalent with identical functionality but rated for -40°C to 85°C operation.
