Hi JT,
So we don't have any specific boards for our quad RS-422 devices.
For the 7 RS-422 outputs the AM26LV31E (2x of them) would be good for the outputs - we don't have a specific board to test this. In the past when we test these or other quad…
Hi,
I got an instrument with RS485 interface.
But the baudrate is 111111,9,n,1.
Does TI have RS485 IC or EVM can support it?
Sorry, Eric,
I always use a module like USB to RS485 converter.
I'm not familiar with RS485, so I can't answer…
Hi Art,
The THVD2450 could suit your customer needs. It is TIA/EIA-422 standardized and can output TTL voltages. It's signaling rate can support up to 50Mbps. There is also a EVM board available on the product page here .

I assume you want to put the device at maximum data rate with maximum load with both TX and RX on.
As I mentioned, I think you can check out the EVM.

Other Parts Discussed in Thread: ADS122U04 Hi Team,
Is there any ADC or EVM which has RS485 interface? Input: 0-5V DC Resolution:24bit Sample rate: more than 36KHz
Best Regards, Tom Liu
Ottey-san,
Please let me know if you have any updates. I suspect this behavior is application related. Could you please check the basics like ground, load, etc? We haven't seen this in the lab. You can also get the EVM to compare the waveforms.

Part Number: OPT8241-CDK-EVM Hi,
I have yet another question (sorry).
Is there any specific reason, why the low ripple ldo's of the TPS659122 remain unused? Shouldn't they be a better choice for e.g. VCC_LDO_1V8?
Thx,
Bernd
Hi Russell,
Would they be OK with evaluating the SOIC package variant instead using RS485-HF-DPLX-EVM? The electrical performance is the same between both package options.

Matsumoto-san,
Thanks for your interest in THVD1450. Yes, during bench tests, one of the tests is to use the single device EVM ( www.ti.com/.../RS485-HF-DPLX-EVM) for IEC61000-4-2 test. The strike point could be on the connector. When we test the device…
