Custome is looking for long length cable 100M with 12Mbps data rat and 3.3V bias power. for MD Encoder Application.
In the SN65HVD23 d/s, it is able to extend cable length, but it only works with 4.5V,min VCC.
Is there 3.3V device with similar performance recommended?
Modern transceivers like the THVD1429 have enough drive strength for long cables. (And if the signal is unidirectional, you can use RS-422 termination, i.e., a resistor only at the receiver.)
The only question is how much jitter you can afford in your application:
It might be possible to improve the signal somewhat with a common-mode choke. But ultimately, this depends on the analog properties of the entire bus, and on what logic you are using at the receiver to decode the signal.
If you need the receiver equalization feature, then the SN65HVD23 is your only choice, and you need a 5 V supply.
