Power supply pins should be bypassed with 10nF ceramic capaci-tors.OPERATING VOLTAGEOPA237 series op amps operate from single (+2.7V to +36V) or dual (±1.35V to ±18V) supplies with excellent performance. Most behavior remains unchanged through-out the full operating voltage range. Parameters which vary significantly with operating voltage are shown in typical performance curves. Specifications are production tested with +2.7V, +5V, and ±15V supplies.OUTPUT CURRENT AND STABILITYOPA237 series op amps can drive large capacitive loads.However, under certain limited output conditions any op amp may become unstable. Figure 1 shows the region where the OPA237 has a potential for instability. These load conditions are rarely encountered, especially for single supply applications. For example, take the case when a+5V supply with a 10k Ω load to V S /2 is used. OPA237series op amps remain stable with capacitive loads up to 4,000pF, if sinking current and up to 10,000pF, if sourcing current. Furthermore, in single supply applications where the load is connected to ground, the op amp is only sourcing current, and as shown in Figure 1, can drive 10,000pF with output currents up to 1.5mA.FIGURE 1.

Materials,Revisions F (23) Hardware Overview 1Hardware OverviewThe PPCMB provides control signals and audio signals to the DUT.The PPC sends the control signals to the TAS1020B device through the USB human-interface device(HID)protocol.The TAS1020B deviceconverts to I2C and sends to the appropriate I2C address.The audio signals are provided through USB audio,SPDIF,or analog signals.The aforementioned signals are converted to I2S–see Figure2.Figure1.PurePath Console Motherboard Revision D3 SLOU366B–June2013–Revised February2015TMHardware Overview Figure2shows the PPCMB Revisions D and E signal flow.For Revision F,refer to the block diagram in Section4.5.Figure2.PurePath Console Motherboard Signal Flow(Revisions D and E)1.1PurePath Console Motherboard Features•The PPC sends I2C control signals through the USB link:the initialization sequence is sent utilizing auto DUT detection reducing hardware setup time•Three I2S audio sources:USB audio,SPDIF,and ADC•Audio processing:TLV320AIC3262(mini-DSP)•Dual asynchronous sample-rate converters(ASRC)PWM modulator:TAS5548•Interface with PurePath Smart Amp and audio devices designed for use in TV,mini-component,AVR application1.2PurePath Console Motherboard FunctionsThe PPCMB is organized into two sections:control data and audio data.Control data is routed through the I2C bus and audio data is routed through the I2S bus.An analog signal can also be routed directly to and from the DUT.The control data is sent from the PPC through the TAS1020B USB to I2C commands.The MPS430™microcontroller can also be used independent of the PC host.The MSP430device is used for stand-alone demonstrations;therefore,it is configured for each application. Hardware Overview The digital audio data input is selectable from USB audio,optical SPDIF,coaxial SPDIF,and analog ADC.When a digital audio data input is selected,the PPC will automatically send appropriate scripts to thedevice in-use.When direct audio analog input is required,the PPCMB will provide this signal through a line-in connector.•TLV320AIC3262(mini-DSP)provides programmable algorithms and audio post-processing for many applications•PWM modulator with dual ASRC and post-processing capability can be used in mini-component or AVR systems.The PWM output is connected directly to TI's high-power(300W)amplifier TAS5624AEVM.•I2S audio from the DUT can be captured through the USB link or optical SPDIF for signal analysis1.3PurePath Console Motherboard Detailed OperationsThe following information can be used as a debugging guide.Upon power-on,the PPCMB uses optical SPDIF input(default).The I2S signals can be seen with anoscilloscope probe at the pin headers LRCLK,SCLK,SDIN,and MCLK.EEPROM1(EP1)is flashed with firmware that runs the TAS1020B for the USB audio(USB-miniEVM), HID,and the USB composite device.Figure3shows the Device Manager.Figure3.Device ManagerWhen the PPCMB is plugged in to a PC,the Device Manager should show all of the USB devices shown in Figure3.If one of the devices does not show up,the PPCMB will not work correctly.When the PPC is executed,the PPC uses the USB audio as the default I2S input.The PCM9211acts as the multiplexor that selects among the following I2S signal sources:optical SPDIF,coaxial SPDIF,andUSB audio.The output of the PCM9211device is routed to the TLV320AIC3262device.The signal from the TLV320AIC3262is then routed to the TAS5548device and the output connector(J1).TheTLV320AIC3262can be bypassed by switching the MUX3select control signal to high and the MUX4,MUX5,and MUX6select control signals to low by using the PPC;and adding jumpers between pins1and 2of the header LRCLK,SCLK,SDIN,and MCLK pins.5 SLOU366B–June2013–Revised February2015TMMicro USB24VDCPSU ANALOGINEXT I2SThe I 2S header pins are used for three purposes:probing I 2S signals coming out of PCM9211,bypassing I 2S signals from TLV320AIC3262and using the PCM9211I 2S signals,and bypassing I 2S signals from the TLV320AIC3262and using an external I 2S source.The TAS5548device is used for PWM input devices such as the TAS5624.The TAS5548is TI's latest 8-channel PWM modulator and has dual ASRC with audio post processing.For more information go to /product/TAS5548.The PCM3168A takes analog inputs (AIN1and AIN2)and routes them to the TLV320AIC3262.AIN1is converted to I 2S and routed to TAS5548and J1.The analog switch,MUX2,routes analog input directly to DUT through J1.The GPIO extender (TCA6424A –U8)is used for initialization of the multiplexors and discrete signals.It is controlled from the PPC through the I 2C.The MSP430is populated but is not programmed.It is used in place of a PC for specifically-designed demonstrations using a combination of TI devices on the PPCMB and a DUT evaluation board or reference boards.2PurePath Console Motherboard Setup and Software InstallationThis section describes the PPCMB setup and software installation.Since the PPCMB connects to one of the DUT EVMs,it is necessary to show the connection in this section.The TAS5760xEVM is used for this purpose.2.1PurePath Console Motherboard SetupFigure 4shows the PPCMB connection.Figure 4.PurePath Console Motherboard ConnectionThe hardware requirements are listed as:•Desktop or laptop PC running
