2.1 AC-MB Settings
2.1.1 Audio Serial Interface Settings
The AC-MB provides the digital audio signals to the evaluation module (EVM) from the universal serial bus
(USB), optical jack, stereo audio jack, and external audio serial interface (ASI) header. Figure 2-2 shows a block
diagram of the ASI routing on the AC-MB.
Figure 2-2. AC-MB Audio Interface Block Diagram
The SW2 switch on the AC-MB selects the audio serial bus that interfaces with the PCM6xx0EVM. Next to the
SW2 switch, the AC-MB has a quick reference table to identify the audio serial interface source options and
switch settings. The AC-MB acts as the controller for the audio serial interface. The AC-MB has three different
modes of operation: USB, optical or analog, or external ASI.
The serial interface clocks and data are provided from the USB interface. The USB audio class driver on the
operating system determines the sampling rate and format. The default settings for the USB audio interface
are 32-bit frame size, 48-kHz sampling rate, BCLK and FSYNC ratio of 256, and the format is time-division
multiplexing (TDM).

2.1.1.1 USB Mode
The OS detects the AC-MB as an audio device named TI USB Audio UAC2.0. Figure 2-3 shows the AC-MB
audio setting for the USB mode of operation.
Figure 2-3. AC-MB USB Audio Setting
2.1.1.2 Optical or Auxiliary Analog Audio Input Mode
Serial interface signals are provided from the PCM9211 digital transceiver, which is capable of sending digital
data to the EVM from an analog input or optical input. Meanwhile, the data from the EVM can be streamed
through the optical output.
Figure 2-4 shows the AC-MB audio setting for the optical and analog mode of operation.
Figure 2-4. AC-MB Optical or Auxiliary Analog Audio Input Setting
The optical output of the AC-MB streams the data captured on the EVM with the format determined by the input
source used. When there is an optical input connected, the LOCK LED must be ON. The PCM9211 streams
the audio serial interface clocks with the format determined by the optical input frame. The digital data from
the optical input is streamed to the EVM. If the optical input is not connected, the PCM9211 captures the input
signal provided through the analog input, and streams the signal to the EVM. This feature can be useful when
a digital input digital-to-analog converter (DAC) is connected to the AC-MB, providing an analog input for quick
evaluation. In auxiliary analog audio mode, the audio serial interface format is fixed to a 24-bit, 48-kHz, I2S
mode.

2.2.1.1 Line Inputs
For the line input configuration shown in Figure 2-8, the TAx5x1x-Q1 captures the audio signal provided through
RCA terminals J2 (IN1), J3 (IN2), header J54, or J55. The RCA white connector is connected to the INxP.
The RCA red connector is connected to the INxM. Depending on the differential or single-ended configuration,
populate the J6 or J7 jumper as described in Table 2-1 accordingly. The input accepted in this mode is a
differential 10-VRMS full-scale audio signal. If a single-ended source is used, the 5-VRMS signal is supported.
The gang potentiometer R50 and R51 provide the input bias resistors for this AC-coupled input mode depending
on the desired input swing and impedance.
Using the TAx5x1x-Q1 AC-Coupled external resistor calculator, enter the maximum input level and the desired
MICBIAS voltage to determine the resistance required to achieve full input swing as shown in Figure 2-10.
From the calculator example below, the maximum resistance allowed is 2399.4 Ohm, and the closest standard
resistance is 2375 Ohm. Based on this standard value resistance, the effective impedance looking into the
device is about 2184 Ohm. This effective input impedance forms a high pass filter with the external capacitor.
The Vcm is the common voltage for the respective MICBIAS and Input Swing. One can adjust the R50 and R51
potentiometer to get the common mode voltage (Vcm). By default, the EVM Vcm is set to 7.3 V.
Figure 2-10. AC-Coupled External Resistor Calculator
2.2.1.2 On-Board Microphone Input
For the on-board microphone input configuration shown in Figure 2-8, the TAx5x1x-Q1 records the audio
captured from MK1 (ECM) or U5 (Analog MEMS) microphones. For U5, the audio port is located at the bottom
of the board. Electret Microphone (MK1) is connected to IN1P/M, and MICBIAS is used to power the onboard
microphone, so header J8 must be installed. The MEMS microphone (U5) can be configured as a single-ended
or differential input and connected to IN2P/M. There must not be any connections to J2 or J3 while the onboard
microphone is used to preserve the performance of the microphone. Gain adjustment can be needed in the
device depending on the microphone sensitivity.
2.2.2 TAx5x1x-Q1 EVM Output Hardware Settings
The TAx5x1x-Q1 evaluation module has several output configuration options and offers flexibility to allow the
user to evaluate the device with different load conditions and configurations. The different configurations are
highlighted in this section.

evaluation. By default, the filter components are not populated.
Switch SW1 allows users to select respective loads for each output pair for 16 Ω, 604 Ω, or 10 kΩ if needed.
These resistors are for quick evaluation and can be bypassed for actual load. SW1 and the output RCA
connectors are located on the top left-hand side, shown in Figure 2-12.
Figure 2-11. TAC5x12-Q1 EVM Output Architecture for Channel 1 and 2
OUT1 and OUT2 audio output pins have connection options with external load or the on-board load selections.
A pair of RCA connectors, white from OUTP and red from OUTM, allow users to connect to external devices as
differential or single-ended. Jumper header J36 or J37 must be populated if single-ended is desired or removed
for differential configuration.

(ASI2). In Audio Serial Interface, GPI2A can be configured as either the WCLK, BCLK, or DIN in peripheral
mode, as shown in Figure 2-22.

2.8 I2C Address Hardware Configurations
Configuring the address of the TAx5x1x-Q1 device on the EVM is typically not required for evaluation use;
however, configuring the address is supported by placing jumper on header J46 to either low (ground) or high
(pull-up to AVDD). Header J73 needs to be populated on pin 1-2.
ADDRA Level Device Address (7-bit
Addressing)
Device Address (8-bit
Addressing)
AVDD 0x51 0xA2
GND 0x50 0xA0

2.9 Audio Serial Interface Hardware Configurations
The TAx5x1x-Q1 EVM supports the Secondary Audio Serial Interface (SASI). By default, the EVM is configured
for Primary Audio Serial Interface (PASI) from the AC-MB with jumpers populated on header J43 pin 1-2 and pin
3-4. If secondary ASI is desired from AC-MB, remove jumpers on header J43, place jumper on header J67 pin
1-2, and configure TAx5x1x-Q1 device for a secondary audio interface.
Figure 2-23. AC_MB Audio Serial Interface Connection
The external audio interface can also be used for SASI with header J66. To make parameter measurements on
SASI with the external audio instrument, remove the jumpers on header J43 and place jumper on header J67 pin
2-3, as shown in Figure 2-24.
