TRF7962A: extend distance

rei

Part Number: TRF7962A

Hi,

My customers made a product using TRF7962A. It can communication normally between 0~60mm, however at 100mm, it will cause a collision error.

 

Question:

Is there a register that extends the communication's distance (increase output) at ISO15693?

 

Regards,

Rei

    Hello Rei,

    there is a bit in the "Chip Status Control" register which let you select between half and full power for the transmitter, but the default for this register setting is full power. I assume  that this is still at the default and so at full power. Also the Supply Regulator (reg. 0x0B) settings are by default at the higher voltage.

    As far as I know these are the only register settings that can influence the transmitter power.

    Best regards,
