I am trying to configure AX5043 transceiver(ONSEMI) for PSK modulation and system parameters are as follows:
Modulation : BPSK Carrier Frequency : 437.025MHz AX5043 chip is interfaced with PIC18F4550 micro controller using SPI. AX5043 is connected to Crystal Oscillator of 32MHz. Using internal VCO.
Now when I try to do auto ranging for the desired frequency, 437.025 MHz, which is configured in FREQA register(s), I am getting an auto-ranging error, i.e. RNGERR bit is going set after auto ranging is completed.
Can anyone help me with this?
