VCC

Two external power supplies are required to operate the RB-TK2051: VCC (referenced to GND), and V5

(referenced to G5). The V5 ground (G5) must be kept separate from the VCC ground (GND). GND and G5 are

joined at a common point on the RB-TK2051 with a 0Ω resistor (R1).

The Minimum and Maximum VCC supply voltages are +10V and +30V, respectively.

The V5 supply voltage is 5V. Please see the TK2051 Data Sheet for Minimum and Maximum values.

The VCC and V5 power supply connection (JP2) is a standard 4 pin, .156” Molex header. Please refer to the

Board Connection Diagram for the connector locations on the RB-TK2051.

OUTPUT

The output connection (JP3) for the RB-TK2051 is a standard 4 pin, .156” Molex header. The output of the

TK2051 is differential; therefore each output has a positive output (OUT1+ and OUT2+) and a NEGATIVE

OUTPUT (OUT1- AND OUT2-).

Please refer to the Board Connection Diagram for the connector locations on the RB-TK2051.

INPUT

The input connection for the RB-TK2051 is a dual RCA connector (JP1). The RCA connector is labeled IN1 and

IN2 on the bottom of the PCB. These inputs share a common ground referenced to G5. Please refer to the

Board Connection Diagram for the connector locations on the RB-TK2051.
