TMS320F280049: FSI capabilities and bench testing result

Part Number: TMS320F280049
Other Parts Discussed in Thread: TMDSFSIADAPEVM

Hi expert,

My customer would like to have test data on FSI. They especially care about data rate/communication distance. Could you provide me this data with below details in testing?

1. Transceiver used

2. Data rate

3. Cable type

4. Distance

5. Topology




  • Hi Sheldon,

    The TMDSFSIADAPEVM User's Guide includes test data for both on-board LVDS and RS485 differential drivers / receivers / transceivers. It also offers some details on potential topologies and points to SPRACM3 for more details.

    Reliable test results were the following between each node device. Let me know if you have any questions on this.

    • LVDS = 10m CAT5 cable, 50 MHz FSI frequency (up to 200Mbps with two data lines)
    • RS485 = 15m CAT5 cable, 25 MHz FSI frequency (up to 100Mbps with two data lines)
