TJA1100 Test Mode 2 no 33MHz

Hi there again,

I would like to test the PHY in our application. Therefore I have to set the PHY in test mode 2. When I do so, the PHY suddenly gives out a 833kHz jitter instead of the expected 33.3MHz. could you pls tell me why this is so?

Do you have any further information using the PHY in the test modes instead of the rare infos in the datasheet?

We look up the OABR Specs V3.2 and other . There is nothing about the 833kHz. The provided test software expects the 33.3MHz.

 

Anyone can help with further information or sheets where the tests are described any further?

 

Regards

Jérôme
