Hello,
I try to use TMS3705EQ1 to demodulatethe response of the transponder.
In a normal operating, We recept a code only when there is a transponder in the field of the antenna. Otherwise, there is 0Vpp on SCIO pin. Is That right ?
I recept the correct code when I put a transponder on the antenna, unfortunetely even if I don't have transponder next to the antenna, I have somthing, "like a signal", on SCIO pin. I would to have 0Vpp when there's no transponder.
Would you know why ?
You could find attached my schematic
Thanks
