AMIS-52100
Low-Power Transceiver with Clock and Data Recovery
Data Sheet
8.2 VCO1, VCO2, Voltage Controlled Oscillator Tune
The VCO1 and VCO2 pins connect a parallel combination of a capacitor and an inductor to the AMIS-52100 internal voltage controlled
oscillator (VCO). The external LC (parallel inductor and capacitor) circuit sets the frequency of the internal VCO. The VCO frequency
must be set to be twice the desired TX or RX frequency of the AMIS-52100. The range of the VCO frequency is 600MHz to 1536MHz.
The voltage on these pins can be used to indicate proper operation of the AMIS-52100 PLL/VCO circuits, refer to the AMIS application
note; “First Time Users Guide to working with the Transceiver IC” for more information.
