Hi TI Team,
I need your guide with Serializer and Deserializer configuration. Any suggestion will be very much appreciate.
Please see my questions below.
Objective:
I need setup communication between Serializer (DS90UB949EVM) and Deserializer (DS90UH498) to processing some image from computer to a touch display.
I am seeking your help on how to configure these two board together in order to achieve the desired out.
Equipment:
- Serializer (DS90UB949EVM)
- Deserializer (DS90UH498)
- Dacar 535 4-Core (Coaxial Cable)
- HDMI
- LVDS
- Analog LaunchPAD (Software)
Test Setup:
Background:
I have read Serializer and Deserializer datasheets and the information provided was not quite clear to me, hopeful with your help all will make a bit more sense.
I understood that for both boards to communicate with each order some software and hardware configuration are required, such as MODE_SEL0 (Output), MODE_SEL1 (Input), IDX(Input).
Serializer Datasheet EVM (Configuration Select, pg12): No resistors table were provided but table with combination of bit setting (Table 1-12 & 1-13) were provided.
- Supposed in MODE_SEL 0 I have decided to select Mode 4 (EDID_SEL = 0, AUTO_SS = 1, AUX_I2S = 0).
- For MODE_SEL 1, must I select the same MODE 4 (EXT=0, COAX=0, REM=0)? Is this configuration is done in software? If so, can you provide some guide?
Deserializer Datasheet (Configuration Select, pg42): Table of resistors were provided with values and it advice to choose R1 – R2 based on the Output Mode expected to use.
My customized board with Deserializer has no strap resistors therefore I am not sure about selecting the right value from the Table-8 to match my serializer. For example:
- For MODE_SEL 0. Must I select No# 4 (R1 = 73.2k, R2 = 15k) Dual SWAP Output?
- For MODE_SEL 1. Must I also select No# 4 (R1 = 73.2k, R2 = 15k) Coax?
Given the setup I am referring, is the statement below are true?
Deserializer
- MODE_SEL0 (configure the output of serializer which will matches Deserializer input)
- MODE_SEL1 (configure the input of serializer from HDMI)
Deserializer:
- MODE_SEL0 (configure the output of Deserializer to must match with LVDS input display)
- …
Thank your
