2 PLVLSET AGC Loop Threshold-Level Input/Attenuator Control
3 CTRL2 Functional Control Bit (see Table 1)
4 V
CC_A
Power-Supply Input. Bypass to ground with a 10nF capacitor as close as possible to the pin.
5 IF_IN
Attenuator Input (50I). Requires a DC-blocking capacitor.
6 AMP_OUT Error Amplifier Output
7, 14 GND Ground
8 DET_VIN Error Amplifier Input Voltage from an External Detector
9 LO+ Positive LO Input. Requires a DC-blocking capacitor.
10 LO- Negative LO Input. Connect to ground.
11 V
CC_LO
LO Driver Supply Voltage Input. Bypass to ground with 1FF and 10nF capacitors as close as
possible to the pin.
12 ALM Alarm Logic Output
13 V
CC_RF
Mixer Supply Voltage Input. Bypass to ground with a 10nF capacitor as close as possible to the
pin.
15 RF_OUT Mixer Output. Requires a DC-blocking capacitor.
