DS110RT410: Open Inputs

Part Number: DS110RT410

Hi Experts,

Our customer is currently designing using only two of the four channels of the DS110RT410SQE/NOPB device.
We can´t find any information in the datasheet about the termination of unused channels.
At the moment the customer is connecting all unused RX-pairs (positive and negative line) directly to GND (e. g. Pin 4 and 5).

We hope to receive your confirmation/advice.

Thank you and best regards,

Gerald
