1. A bimodal power data link transceiver device, the device comprising:

  • a transceiver integrated circuit (IC), the transceiver IC comprising;

    a transmitter, the transmitter having;

    partial voltage controlled oscillator (VCO) designed to accept at least one input from frequency setting components external to the transceiver IC and in combination with the frequency setting components to produce a first clock signal at a first frequency set by the frequency setting components;

    a first power amplifier, the first power amplifier coupled to the partial VCO; and

    a receiver;

    a second power amplifier coupled to the first power amplifier;

    a transmit/receive switch coupled to the second power amplifier and the receiver;

    a controller coupled to the transceiver IC;

    a direct digital frequency synthesizer having an output coupled to an input of the transceiver IC;

    a complete voltage controlled oscillator (VCO) coupled to the partial VCO, the complete VCO configured to produce a second clock signal at a second frequency and to couple the second clock signal to the partial VCO the complete VCO further configured to utilize the partial VCO as one of an emitter follower circuit, a buffer or a filter; and

    a loop filter coupled to the complete VCO and the transceiver IC.
