HTRC110 AC vs MC

Hi,

I have a question regarding the reading of HITAGS transponder with HTRC110.

As I would like to read the UID of the transponder the reading distance is ~3-4cm (from the center of the

antenna). But when I receive only with Manchester the reading distance is ~8-9cm.

As I see the timing in the beginning of the AC coding is really small.

The bits of the SOF is between 30us - 140us.

Do you have any idea why I got this?

Thank your for your help in advance.

Best regards,

Sandor

Dear Jonathan,

Yes, I use the mentioned documentation.

The MODE pin connected to VSS and I use this IC with 16MHz clock.

Do you have any idea why I get this result?

Thank you for your help in advance.

Best regards,

Sandor

Dear Sandor Bedo,

please confirm you are using the AN98080 also which reader you are using to communicate with the HTRC  also  that you are following the clock section and that you are using the glitch filters on.

Have a great day !

Jonathan
