Implementation Guide

2.7

Reference CLK Programmability

The SN65DSI8X EVM incorporates a programmable CLK circuitry using a TI-programmable device,
CDCEL913. The output of the CDCEL913 is connected to the reference CLK of the SN65DSI8X. The
default frequency of the reference CLK is 27 MHz. The CLK can be programmed via I

2

C signals brought

out to on-board connectors J9, J12, or J10. When J10 is used, place jumpers on J9 and J12. The
reference CLK can be pre-programmed to a desired value, if requested prior to shipping.

2.8

DIP Switch Configuration

A DIP switch is provided to operate the device or EVM in different configurations. When the switch is in an
open position, the corresponding signal is tied high. When the switch is in the ON (closed) position, the
corresponding signal is tied to GND.

The signals in the greyed out region are not enabled unless a corresponding resistor is installed.

Quick Start Guide

Quick-start instructions are provided in the following list:

1. Plug in a DSI source to J4

2. Plug in a LVDS video sink device on J2, J5 or J6

3. Plug in an I

2

C host on J10 if an external I

2

C host is used.

4. Make sure the DIP switch setting is in a correct configuration.

5. Apply power to the EVM. The following LEDs should light up: D3, D6, and D7. D1 may light up

depending on the configuration.

6. Start video streaming on the DSI input

7. Configure the device for the desired mode of operation via I

2

C. Video output should be observed after

configuration is complete.
