DS90UB913A-Q1: forward channel frame protocol

Part Number: DS90UB913A-Q1

Hello Guys,

Good day.

Our customer are interested on how the data transfer between Serializer and Deserializer is handled. He need to know how the forward channel frame (protocol) is built up exactly (bit by bit).

He found out that the protocol is either composed of 28-Bit or 40-Bit and uses 8b/10b encoding, the data packet contains payload data, 2 embedded clock frames, DCA and DCB bits and there are control bits (I2C/SPI, GPIO, CRC). But there is not information on TI site and trining materials on how the frame is built up exactly.

Thanks and regards,

Art

    Hello Art,

    The datasheets for the devices give basic information like the above regarding the serialization protocol, however the low level detail you are inquiring about is not shared publicly since FPD-Link is a proprietary technology. The specific makeup of the protocol including packet format, scrambler seed, etc. are considered TI IP. 

    Best Regards,

    Casey
