I2C Setting for DS90UB914A / 913A using TI eval boad

Hi,

1) We have set up the prototype board of using TI eval board with Aptina Image sensor AR0132 as block diagram below.

2) We tried to set the I2C setting for Der & Ser to control the Image Sensor at Ser side, however the I2C cannot reach image sensor. Below is my register setting sequence:-

0xC0 (Slave address for Der)

0x21 (Register setting for I2C pass through all bit 7)

0x80 (Value setting for I2C pass through all)

0x08 (Resister address for Slave ID[0])

0x90 (I2C Device ID value of 0x90)

0x10 (Slvae Alias[0])

0x90 (I2C Device ID value of 0x90)

3) After the setting and tried to send other address, there is no data signal our from Ser I2C pin.

4) Can you recommend me what is the correct I2C setting to control Camera Sensor?

Thanks.

    Hello,

    Do NOT set pass-through ALL on either the serializer or deserializer. By default, 0x21[7] = 0 and 0x03[3] = 0 and these bits should not be changed. Normal I2C pass-through should be ON, although this is turned ON by default upon power-up (0x03[2] = 1).
