[Elecraft] XG3 synthesizer question

2012-07-23 Thread Todd Doucet
The schematic on page 25 of the XG3 manual shows that U1 is a CS2100, which I assume is a Cirrus Logic CS2100-CP (the one with I2C). The datasheet says (as I understand it) that the output frequency from the chip is 6 to 75 MHz (pin 3). The Elecraft specs say the unit outputs 1.5 MHz to 200 MHz
