Question about "RxThreshold" in CLRC663

[jylee]

Hello,

Would you someone please explain about the meaning of value in "RxThreshold(0x37) - MinLevel and MinLevelP." register?

In the data sheet, just described as below.

Bit        |   Symbol        | Description
7 to 4   |   MinLevel      | Defines the MinLevel of the reception.
                                       Note: The MinLevel should be higher than the noise level in the system.
3 to 0    |   MinLevelP   | Defines the MinLevel of the phase shift detector unit.

And I can see how to set the value in "AN11019 - CLRC663, MFRC630, MFRC631, SLRC610 Antenna Design
Guide".

But, there is no description about what a number which can be set from 0x0 to 0xF stand for.

Thanks in advance.

Hello,

Please see below answer from Apps team:

MinLevel is a dedicated Level related to your receiver Input Voltage. We do not provide absolute values, because they do not help you at all and they are dependent on the RX voltage level. As described in the Antenna design AN this Level is easy to find. The same for MinLevelP. There is only one way how both Levels are optimized and this is described in Antenna design AN.

Regards,

Ivan.
