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