3 Hardware Configuration
This section describes the various portions of the TSW14J58EVM hardware.
3.1 Power Connections
The TSW14J58EVM hardware is designed to operate from a single supply voltage of +5.5 V DC. The power
input is controlled by the on and off switch, SW5. Make sure this switch is in the off position before inserting
the provided power cable. Insert the connector end of the power cable into J2 of the EVM. Connect the positive
red wire end of the power cable to +5.5 V DC output of a power supply rated for at least 5 Amps. Connect
the negative black wire to the RETURN or GND of the power supply. The board can also be powered up by
pro5.5 V DC to the red test point, TP18, and the return to any black GND test point. As an example, the
TSW14J58 draws approximately 0.6 A at power-up and 3 A when capturing 8 lanes of data from an AFE at a line
rate of 24.33 Gpbs.
Note
The typical power supply range for the TSW14J58EVM is 5.5V with a power consumption of about
16.5W. It is recommended that at least a 5 A rated supply be provided to the TSW14J58EVM due to
the current consumption increase when data is being captured by HSDC Pro.
