RF Accuracy from VCTCXO Specification

Hi

If the transceiver is transmitting at 433 MHz, with a reference VCTCXO of 30 MHz ±1 ppm, does that mean that the transmitted frequency accuracy will be:

(433/30) * 1 ppm * 30 = ±433 Hz.

So, the transmit frequency would be 433 MHz ±433 Hz? Not taking into account any tolerance of the transceiver chip itself though.

Yes, your math is correct.

There will be no additional tolerance from the transceiver chip because you are using a PLL.
