TCAN1042-Q1: Duration of the low-level pulse on the rx pin

Part Number: TCAN1042-Q1

Hi Team,

Our customer would like to know the duration of the low-level pulse on the rx pin of TCAN1042-Q1. According to our customer,

In the datasheet, there is a timing I cannot find. When the chip recognize a wake-up pattern on the line, a low-level pulse on the rx pin is sent. I would like to catch this pulse but not react to normal transmission on RX line.

How long is this pulse. I attached the datasheet section that show this pulse.

Regards,

Danilo

    Danilo,

    The pulse the customer is referring to is the dominant on the RXD line after the device responds to the wake-up pulse. The RXD dominant pulse is totally dependent on how long the CAN bus is held dominant. There's no specific timing for the RXD low pulse.
