SN65DP141: Spec of Minimum Input Range?

Martin Seeger

Part Number: SN65DP141

Dear Team,

hope that you had a nice Thanksgiving & weekend.

Our customer is interested in the DP141 but asked if we have more details about the minimum input amplitude (RX) spec of the device. DP specs it to be 120mV, but apparently some other parts can do better, like 90mV.

Looking forward to your feedback.

Best Regards

Hi Francisco,
thanks for the answer.
The customer stated that the DP spec required a minimum of 120mV input signal amplitude. (I could not find the DP spec online, maybe you have it internally?). Other parts from different supplier guarantee to work with only 90mV.
In our data sheet we do not spec the minimum input amplitude which is required for the DP141 to properly work.
Best Regards
Martin

Hello Martin

Do you know which spec they are checking? I check the DP1.2a spec and it says that works as a minimum of 70mV.
The DP141 works with CML that's why it doesn't have specified the input voltage. On the other hand, we have the DP159 that it has VID (input differential voltage peak to peak) from 75 mVpp to 1200mVpp. Please take a look at this one and let me know your comments.

Regards
Francisco
