SN65DSI83, SN65DSI84, and SN65DSI85 EVM User’s Manual and
Implementation Guide
1 Overview
1.1 What are the SN65DSI83, SN65DSI84, and SN65DSI85?
The SN65DSI8X is a MIPI DSI-to-LVDS bridge device that supports video modes in the forward direction.
The SN65DSI8X is primarily targeted for portable applications such as tablets and smart phones that
utilize the MIPI DSI video format. Use the SN65DSI8X between a GPU with DSI output and a video panel
with LVDS inputs.
All three devices share the same pin out and package.
Table 1 is a summary of the feature sets on these devices:
Table 1. SN65DSI8X Features Summary
Part Name Description Max Resolution
SN65DSI83 Single-channel DSI to single-link LVDS Suitable 1366×768/1280×60 fps at 24 bpp/18 bpp
SN65DSI84 Single-channel DSI to two single-link LVDS 1920×1200 60 fps at 24 bpp/18 bpp
SN65DSI85 Dual-channel DSI to two single-link LVDS 2560×1600 60 fps, 1920×1080p 120 fps at 24 bpp /18 bpp
NOTE: Each DSI channel has 4 DSI data lanes + 1 CLK lane. Each LVDS link has 4 data lanes + 1
CLK lane.
1.2 What is the SN65DSI8X EVM?
The SN65DSI8X EVM is a PCB created to help customers implementing SN65DSI83, SN65DSI84, and
SN65DSI85 in system hardware. This EVM can be used as a hardware reference design for any
implementation using the SN65DSI8X. The SN65DSI8X EVM is designed for use across all three versions
of the DSI bridge devices - SN65DSI83, SN65DSI84, and SN65DSI85. PCB design and layout files are
provided upon request to aid PCB design with a SN65DSI8X component. The layout files are used as a
guideline to implement the SN65DSI8X with illustrations of the routing and placement rules. Please note
that the EVM design includes test components to evaluate the SN65DSI8X which may not applicable for
production.
This EVM includes on-board connectors for DSI input and LVDS output signals. These connectors
connect MIPI DPHY-compliant DSI source and LVDS panels to the EVM. Refer to
Section 2.1 and
Section 2.2 for more information on the connectors.
CAUTION
A custom translator cable or card is required if this EVM is to be utilized for the
evaluation of an implementation from the customer. Any other method of
connecting to any DSI source or LVDS panel is not supported by this EVM. TI
is not responsible for any issues or problems that may occur as a result of
using connection methods other than what is recommended in this document.
NOTE: Some portions and components in the EVM or in this document may include the references
to SN65DSI85 instead of addressing all three part numbers. The SN65DSI85 is replaceable
with SN65DSI83 or SN65DSI84.
