Dear TI

I want to implement this circuit as shown block diagram below. Recommend reference Docs and interface products.

(422/485 cable is long, ~50cm, flat cable)

Hi Choi,

We have many options for RS-422 and RS-485 transceivers that could potentially fit into this schematic. My first thought is to recommend THVD1410 (500kbps) and THVD1450 (50Mbps) depending on the data-rate of the PWM signal. This family of devices can be powered by a 3v or 5v supply and are compatible with 3v input logic (output logic at Vcc level).

Here's a link to our RS-485 Design Guide for more reference. Let me know if your system has other requirements and we'll provide more specific recommendations.

Regards,
Eric
