PGA900: Could PGA900 have RS485 output with SN65HVD7?

Part Number: PGA900

Hi:

We want to have RS485 output with PGA900 solution.

I have some questions 

1. what is the max baud rate of UART ?

2. Could PGA900 have  RS485 output with TI SN65HVD7? 

3.The min supply voltage of SN65HVD7x is 3V.  Can I use AVDD of PGA900 as power supply of SN65HVD7X?

thanks

    Hello,

    1. The fastest baud rate available is 83333 baud. 

    2. Yes you could configure the UART with an external RS485 transceiver to communicate over RS485.

    3. The maximum external current load on the AVDD regulator is 4mA, which would not be enough to drive the SN65HVD7X.

    Regards,
