Question for TJA1100 LPF

[lipingren]

Hello NXP,

In your application hints of AH1310, external low-pass filter is recommended to use as shown in Page 17 “Fig 11. MDI diagram (default filter). I want to know do you have integrated low-pass filter inside your TJA1100 on TRX_P and TRX_M pins?

Thanks,

Liping

Hello Liping,

No, there is no integrated low pass filter inside the TJA1100 on TRX_P and TRX_M pins.

It is strongly recommended to add the external low pass filter with the recommendations on section 3.4.3 (Page 17) and Figure 11 (Page 16) of the Application hints AH1310 document.

Best regards,

Tomas
