SN65DSI86ZXHR

Specialized Overview

The SN65DSI86ZXHR is a MIPI DSI to embedded DisplayPort (eDP) bridge manufactured by Texas Instruments. It features a dual-channel MIPI D-PHY receiver front-end with four lanes per channel, operating at up to 1.5 Gbps per lane for a maximum input bandwidth of 12 Gbps. The device converts formatted video data streams to DisplayPort with up to four lanes supporting rates from 1.62 Gbps to 5.4 Gbps. It supports 18 bpp and 24 bpp DSI video packets in RGB666 and RGB888 formats. Key electrical parameters include a 1.2-V main VCC power supply and a 1.8-V supply for digital I/Os. The component operates within a temperature range of –40°C to +85°C and is packaged in a 64-ball 5-mm x 5-mm nFBGA.

Specialized Procurement Notes

Verify the specific ordering suffix ZXHR corresponds to the nFBGA package type when sourcing components. Confirm that the revision history indicates the ZXH package offers datasheet-equivalent electrical performance compared to previous MicroStar Jr. BGA designs. Ensure compatibility with the required I2C configuration settings for the target application environment.

Specialized Selection Notes

Select this component when interfacing MIPI DSI sources with eDP displays requiring high-resolution support. Consider the dual-channel architecture for applications needing increased bandwidth or redundancy. Evaluate the thermal characteristics and power supply requirements against the system design constraints to ensure stable operation across the specified temperature range.

Specialized Part Context

The SN65DSI86 belongs to the SN65DSI86 series of display interface ICs designed by Texas Instruments. This series focuses on bridging MIPI DSI interfaces to embedded DisplayPort standards. The device is part of a broader family of display controllers aimed at modernizing display architectures in portable and industrial electronics.

Specialized Replacement Considerations

The datasheet notes that the ZXH package replaced the discontinued MicroStar Jr. BGA package while maintaining footprint equivalence. No other direct substitute part numbers are explicitly listed in the provided documentation.
