Tool Is For Evaluation Of
AS3993
For Use With
AS3993 UHF RFID Reader IC
AS3993 – AN13 – Received Signal Strength Indicator (RSSI)
The pads J1 and J2 are connected to the OAD pins of the reader IC which can be used to output
analog/digital RX subcarrier signals or TX / RX based band signals.
The controller part contains the low cost MCU and the LDO used for reducing the USB voltage
down to 3.5 Volts. All the interfaces (USB, UART, …) are located on the controller part as well.
In order to allow USB functionality across all tolerances a crystal with 12 MHz is available.
