Overview www.ti.com Figure 2. TAS5719EVM Printed-Circuit Board The EVM together with other TI components on this board, is a complete 2.0-channel digital audio amplifier system. The MC57XXPSIA Controller board includes a USB interface, a digital input (SPDIF), analog inputs via the ADC, power inputs, and other features like a mute function and power down.

Installation 2 www.ti.com Installation This section describes the EVM and software installation. 2.1 EVM Installation 5V Supply for System Power Analog In to ADC Coaxial SPDIF Input Headphone In Optical SPDIF Input USB Port Headphone Out 4.5V–26V Supply for Output Power Speaker Out A & B Speaker Out C & D Figure 4. General Connection Picture The following are the basic tools for the initial EVM power up. • 5V, 1A power supply (VIN) • 4.
PAGE 5
Installation www.ti.com 2.1.2 PSU Interface The TAS5717/19EVM is powered by two power supplies connected to the MC57xxPSIA controller board: a 5V power supply (VIN), and a 4.5V-to-26V (PVDD) power supply. The 3.3V level is generated from the 5V supply by an on-board voltage regulator. NOTE: The power-supply cable length must be minimized. Increasing the length of the PSU cable increases the distortion of the amplifier at high output levels and low frequencies.
PAGE 6
Installation 2.1.5 www.ti.com Digital Audio Interface SPDIF The Digital Audio Interface SPDIF (RCA/OPTO) accepts digital audio data using the I2S protocol. See the TAS5717/19 data sheet for more information. The RCA connector and the OPTO connector are the two SPDIF interfaces on the MC57xxPSIA board. The switch S3 toggles between the OPTO and RCA connector to accommodate the signal source.

Using the EVM Software 3 www.ti.com Using the EVM Software Figure 8. Main GUI Display 3.1 Connect the GUI to the EVM Open the GUI by clicking Start → All Programs → Texas Instruments Inc → TAS57x → TAS57x GUI. Connect the MC57xxPSIA board (attached to the TAS5717EVM) to your PC with a USB cable. In the Properties window, select 1-band or 2-band DRC and select Stereo or Woofer. Stereo is selected for BTL and Woofer is selected for PBTL Mode. This sends the initialization commands to the device.
PAGE 9
Using the EVM Software www.ti.com 3.3 Volume Function The Individual and Master volume can be selected, and the required volume value can be entered in the Properties window after selecting the function with the mouse. (See Figure 10.) Figure 10. Volume Control 3.4 Speaker/Headphone Selection The user can use the GUI to select whether the TAS5717/19EVM will drive a speaker load or a headphone load. To select a headphone output, click the PWM_OUT setting and select "Headphone" in the Properties window.
PAGE 10
Using the EVM Software www.ti.com Figure 13. Biquad GUI Window A check mark selects the Biquad. If not selected, the Biquad is in ALL PASS Mode. The frequency response and phase response plots for the current settings can be viewed and adjusted in the Frequency Response and Phase Response areas of the Biquad GUI as shown in Figure 13. The individual Biquad gains must be within ±12db.
PAGE 11
Using the EVM Software www.ti.com The crossover frequency for the 2-band DRC by default is 300Hz. This can be modified by entering a new value in the property window. The DRC rates for the softening filter, attack, and release can also be adjusted. To set these rates, first click on the UPPERBAND or LOWERBAND block. Second, set the RateSliders property to On for that block. Third, double-click on the block to bring up an advanced DRC options window, as shown in Figure 15. Figure 15.
