A trainable transceiver is provided for a vehicle for transmitting signals to a device remote from the vehicle. The trainable transceiver includes a programmable oscillator for generating a signal having a selected reference frequency; an RF transceiver that receives an RF signal during a training mode in order to learn characteristics of the received RF signal, and transmits an RF signal to the remote device in an operating mode where the transmitted RF signal includes the learned characteristics of the received RF signal, wherein the RF transceiver receives the reference frequency from the programmable oscillator and uses the reference frequency to learn the characteristics of the received RF signal and for generating the transmitted RF signal; and a controller that, during the operating mode, selects frequency control data representing a frequency and selects the selected reference frequency for the programmable oscillator as a function of the frequency control data.
