This threshold is based on the conversion characteristic of the current shunt monitor circuit of U1101.

    3-22 Theory of Operation: Transceiver Board 3.1.4 Frequency Generation Unit (FGU) The frequency-generation function is performed by several ICs; multiple voltage-controlled oscillators (VCOs); and associated circuitry. The reference oscillator provides a frequency standard to the Trident IC, which controls the VCOs via the port expander. There are also buffers that amplify the VCO signal to the correct level for the next stage.
