Power Supplies

VD+ - Digital Positive Supply.

Digital positive supply voltage. Nominally +3V

VA+ - Analog Positive Supply.

Analog positive supply voltage. Nominally +3V.

DGND - Digital Ground.

Digital ground, 0V, connection.

AGND - Analog Ground.

Analog ground, 0V, connection.

TGND1, TGND2 - Transmitter Grounds.

LED Transmitter grounds, 0V, connections.

Analog Pins

LED1C, LED2C - Transmit LED Cathode.

These pins are connected to the transmit LED cathode via resistors. Appropriate resistor choice

allows user setting of LED current options. The anode of the LED is connected to the positive

supply.

PINC - Receiver PIN Diode Cathode

Receiver PIN diode cathode.

PINA - Receiver PIN Diode Anode.

Receiver PIN diode anode.
