Function
Input current, bias voltage approximately GND
Input current, bias voltage approximately GND
External resistor to GND sets frequency of oscillator A
External resistor to GND sets frequency of oscillator B
Ground
Digital control of channel 2 (low active)
Digital control of channel 3 (low active)
Digital control of channel 4 (low active)
Digital control of channel 5 (low active)
Enables output current (high active)
+5 V power supply IOUT
Enables RF oscillator (high active)
High: selects IOUTA, RFA, RSA
Low: selects IOUTB, RFB, RSB
