Installation
The switch S3 toggles between the OPTO and RCA connector to accommodate the signal source. When
the RCA cable or optical cable is connected and the signal source is powered up, verify that the SPDIF
lock indicator (blue LED5) illuminates, confirming that a viable signal is available to the device. Install a
jumper on JP4 across the middle pin and the pin marked SPDIF to connect the digital source to SDIN1.
Install a jumper on JP5 to connect the digital source to SDIN2.

ADC Interface
In the absence of a digital signal source, the PCM1808 ADC can be used to convert an analog audio
signal to a digital signal to the TAS5713. The DIR9001 still provides clock signals to the ADC in this
process. A 12MHz crystal is installed on the MC57xxPSIA board. The ADC is an additional feature of this
board to provide flexibility in sourcing an audio signal to the TAS5713. Review the PCM1808 data sheet

Board Power-Up General Guidelines
Connect the MC-57xx and the TAS5713EVM boards by locating pin 1 on each board, indicated by a small
white triangle. The MC-57xx plugs down onto the TAS5713EVM board (i.e., the TAS5713EVM board fits
underneath the MC57xxPSIA board). Pin 1 on each board must be connected to each other.

Install the EVM software on the PC before powering up the board. After connecting the loudspeakers or
other loads, power supplies, and the data line, power up the 5V power supply first; then power up the
PVDD power supply. It is recommended initially to set the PVDD level to 10V, then ramp it up to 20V to
verify cable connections.

Select the appropriate tab; in this case, select TAS5713 tab. It has two subwindows. One shows the
Process Flow window. From the Process Flow window, each of the signal-processing function tools can
be selected by clicking on it. The Biquad GUI and the DRC GUI can be opened by right-clicking. This
window also shows Input select, Mode select, Channel, and Master Volume. All functions are shown in the
