DS92LV1212A: DS92LV1212A COMMUNICATION ISSUE

Part Number: DS92LV1212A

HI  sir. 

    FIG. 1 is the schematic diagram of the connection between the TI chip DS92LV1021A and DS92LV1212A at present. Through the use of fpga to send and receive data, figure 2 is the inter-plate signal connection diagram, and several problems encountered during the development process are as follows:

1. Local (unit) send 10 bit parallel data to DS92LF1021A FPGA, converted to a serial signal to the other board (the host), the motherboard through DS92LV1212A serial signal into 10 bit parallel data to the FPGA, the link test no problem.

2. The local (unit) transmits the serial signal of the other board (host) to 10bit parallel signal throughLVDS ISSUE.docx, and the parallel signal is input to the local FPGA, and the data is found to be in error.

  • Hello,

    Can you please clarify the scenario you are describing, especially #2? I am not sure I understand what works and what doesn't. May be you can label the different parts you are referring to.

    On the schematics, why do you need to use so many ac-coupling capacitors C13/C16, C14/C15, C44/C47, C30/C33? Is you data DC-balanced?

    Additionally, I want to attract your attention to the fact that DS92LV1021A and DS92LV1212A are both on a Life-time Buy status. If this is a new development, you should consider using SN65LV1023A and SN65LV1224B instead.
