Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. DESCRIPTION (CONTINUED) The TLV320AIC3262 features two fully-programmable miniDSP cores that support application-specific algorithms in the record and/or the playback path of the device. The miniDSP cores are fully software programmable. Targeted miniDSP algorithms, such as active noise cancellation, acoustic echo cancellation or advanced DSP filtering are loaded into the device after power-up. Combined with the advanced PowerTune technology, the device can execute operations from 8kHz mono voice playback to stereo 192kHz DAC playback, making it ideal for portable battery-powered audio and telephony applications. The record path of the TLV320AIC3262 covers operations from 8kHz mono to 192kHz stereo recording, and contains programmable input channel configurations which cover single-ended and differential setups, as well as floating or mixing input signals. It also provides a digitally-controlled stereo microphone preamplifier and integrated microphone bias. One application of the digital signal processing blocks is removable of audible noise that may be introduced by mechanical coupling, e.g. optical zooming in a digital camera. The record path can also be configured as a stereo digital microphone Pulse Density Modulation (PDM) interface typically used at 64Fs or 128Fs. The playback path offers signal processing blocks for filtering and effects; headphone, line, receiver, and Class-D speaker outputs; flexible mixing of DAC; and analog input signals as well as programmable volume controls. The playback path contains two high-power DirectPathTM headphone output drivers which eliminate the need for ac coupling capacitors. A built in charge pump generates the negative supply for the ground centered headphone drivers. These headphone output drivers can be configured in multiple ways, including stereo, and mono BTL. In addition, playback audio can be routed to integrated stereo Class-D speaker drivers or a differential receiver amplifier. The integrated PowerTune technology allows the device to be tuned to just the right power-performance tradeoff. Mobile applications frequently have multiple use cases requiring very low-power operation while being used in a mobile environment. When used in a docked environment power consumption typically is less of a concern while lowest possible noise is important. With PowerTune the TLV320AIC3262 can address both cases. The required internal clock of the TLV320AIC3262 can be derived from multiple sources, including the MCLK1 pin, the MCLK2 pin, the BCLK1 pin, the BCLK2 pin, several general purpose I/O pins or the output of the internal PLL, where the input to the PLL again can be derived from similar pins. Although using the internal fractional PLL ensures the availability of a suitable clock signal, it is not recommended for the lowest power settings. The PLL is highly programmable and can accept available input clocks in the range of 512kHz to 50MHz. To enable even lower clock frequencies, an integrated low-frequency clock multiplier can also be used as an input to the PLL. The TLV320AIC3262 has a 12-bit SAR ADC converter that supports system voltage measurements. These system voltage measurements can be sourced from three dedicated analog inputs (IN1L/AUX1, IN1R/AUX2, or VBAT pins), or, alternatively, an on-chip temperature sensor that can be read by the SAR ADC. The TLV320AIC3262 also features three full Digital Audio Serial Interfaces, each supporting I2S, DSP/TDM, RJF, LJF, and mono PCM formats. This enables three simultaneous digital playback and record paths to three independent digital audio buses or chips. Additionally, the general purpose interrupt pins can be used to connect to a fourth digital audio bus, allowing the end system to easily switch in this fourth audio bus to one of the three Digital Audio Serial Interfaces. The device is available in the 4.81 mm x 4.81 mm x 0.625 mm 81-Ball WCSP (YZF) Package.

Typical Circuit Configuration Device Connections Digital Pins Only a small number of digital pins are dedicated to a single function; whenever possible, the digital pins have a default function, and also can be reprogrammed to cover alternative functions for various applications. 36 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): TLV320AIC3262 TLV320AIC3262 www.ti.com SLAS679 – DECEMBER 2011 The fixed-function pins are hardware-control pins RESET and SPI_SELECT pin. Depending on the state of SPI_SELECT, four pins SCL, SDA, GPO1, and GPI1 are configured for either I2C or SPI protocol. Only in I2C mode, GPI3 and GPI4 provide four possible I2C addresses for the TLV320AIC3262. Other digital IO pins can be configured for various functions via register control. Analog Pins Analog functions can also be configured to a large degree. For minimum power consumption, analog blocks are powered down by default. The blocks can be powered up with fine granularity according to the application needs. The possible analog routings of analog input pins to ADCs and output amplifiers as well as the routing from DACs to output amplifiers can be seen in the Analog Routing Diagram.

Analog Routing Diagram For more detailed information see the TLV320AIC3262 Application Reference Guide, SLAU309. Analog Low Power Bypass The TLV320AIC3262 offers two analog-bypass modes. In either of the modes, an analog input signal can be routed from an analog input pin to an amplifier driving an analog output pin. Neither the ADC nor the DAC resources are required for such operation; this supports low-power operation during analog-bypass mode. In analog low-power bypass mode, line-level signals can be routed directly from the analog inputs IN1L to the left lineout amplifier (LOL) and IN1R to LOR. Additionally, line-level signals can be routed directly from these analog inputs to the differential receiver amplifier, which outputs on RECP and RECM. ADC Bypass Using Mixer Amplifiers In addition to the low-power bypass mode, there is a bypass mode that uses the programmable gain amplifiers of the input stage in conjunction with a mixer amplifier. With this mode, microphone-level signals can be amplified and routed to the line, speaker, or headphone outputs, fully bypassing the ADC and DAC. To enable this mode, the mixer amplifiers are powered on via software command.

An integral charge pump generates the negative supply required to operate the headphone drivers in dc-coupled mode, where the common mode of the output signal is made equal to the ground of the headphone load using a ground-sense circuit. Operation of headphone drivers in dccoupled (ground centered mode) eliminates the need for large dc-blocking capacitors. HPL HPR HPVSS_SENSE Figure 24. TLV320AIC3262 Ground-Centered Headphone Output Alternatively the headphone amplifier can also be operated in a unipolar circuit configuration using DC blocking capacitors. Stereo Line Outputs The stereo line level drivers on LOL and LOR pins can drive a wide range of line level resistive impedances in the range of 600Ω to 10kΩ. The output common mode of line level drivers can be configured to equal the analog input common-mode setting, either 0.75V or 0.9V. The line-level drivers can drive out a mixed combination of DAC signal and attenuated ADC PGA signal, and signal mixing is register-programmable. Differential Receiver Output The differential receiver amplifier output spans the RECP and RECM pins and can drive a 32Ω receiver driver. With output common-mode setting of 1.65V and RECVDD_33 supply at 3.3V, the receiver driver can drive up to a 1Vrms output signal. With the RECVDD_33 supply at 3.3V, the receiver driver can deliver greater than 128mW into a 32Ω BTL load. If desired, the RECVDD_33 supply can be set to 1.8V, at which the driver can deliver about 40mW into the 32Ω BTL load. Stereo Class-D Speaker Outputs The integrated Class-D stereo speaker drivers (SPKLP/SPKLN and SPKRP/SPKRN) are capable of driving two 8Ω differential loads. The speaker drivers can be powered directly from the power supply (2.7V to 5.5V) on the SLVDD and SRVDD pins, however the voltage (including spike voltage) must be limited below the Absolute Maximum Voltage of 6.0V. The speaker drivers are capable of supplying 750 mW per channel at 10% THD+N with a 3.6-V power supply and 1.46W per channel at 10% THD+N with a 5.0V power supply. Separate left and right channels can be sent to each Class-D driver through the Lineout signal path, or from the mixer amplifiers in the ADC bypass. If only one speaker is being utilized for playback, the analog mixer before the Left Speaker amplifier can sum the left and right audio signals for monophonic playback. ADC / Digital Microphone Interface The TLV320AIC3262 includes a stereo audio ADC, which uses a delta-sigma modulator with a programmable oversampling ratio, followed by a digital decimation filter and a programmable miniDSP. The ADC supports sampling rates from 8kHz to 192kHz. In order to provide optimal system power management, the stereo recording path can be powered up one channel at a time, to support the case where only mono record capability is required. 42 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): TLV320AIC3262 TLV320AIC3262 www.ti.com SLAS679 – DECEMBER 2011 The ADC path of the TLV320AIC3262 features a large set of options for signal conditioning as well as signal routing: • 2 ADCs • 8 analog inputs which can be mixed and/or multiplexed in single-ended and/or differential configuration • 2 programmable gain amplifiers (PGA) with a range of 0 to +47.5dB • 2 mixer amplifiers for analog bypass • 2 low power analog bypass channels • Fine gain adjust of digital channels with 0.1 dB step size • Digital volume control with a range of -12 to +20dB • Mute function • Automatic gain control (AGC) In • • • • • • addition to the standard set of ADC features the TLV320AIC3262 also offers the following special functions: Built in microphone biases Stereo digital microphone interface Channel-to-channel phase adjustment Fast charge of ac-coupling capacitors Anti thump Adaptive filter mode ADC Processing Blocks — Overview The TLV320AIC3262 ADC channel includes a built-in digital decimation filter to process the oversampled data from the sigma-delta modulator to generate digital data at Nyquist sampling rate with high dynamic range. The decimation filter can be chosen from three different types, depending on the required frequency response, group delay and sampling rate. ADC Processing Blocks The TLV320AIC3262 offers a range of processing blocks which implement various signal processing capabilities along with decimation filtering. These processing blocks give users the choice of how much and what type of signal processing they may use and which decimation filter is applied. The choice between these processing blocks is part of the PowerTune strategy to balance power conservation and signal-processing flexibility. Decreasing the use of signal-processing capabilities reduces the power consumed by the device. Table 10 gives an overview of the available processing blocks of the ADC channel and their properties.

Each channel of the stereo audio DAC consists of a signal-processing engine with fixed processing blocks, a programmable miniDSP, a digital interpolation filter, multi-bit digital delta-sigma modulator, and an analog reconstruction filter. The DAC is designed to provide enhanced performance at low sampling rates through increased oversampling and image filtering, thereby keeping quantization noise generated within the delta-sigma modulator and signal images strongly suppressed within the audio band to beyond 20kHz. To handle multiple input rates and optimize power dissipation and performance, the TLV320AIC3262 allows the system designer to program the oversampling rates over a wide range from 1 to 1024. The system designer can choose higher oversampling ratios for lower input data rates and lower oversampling ratios for higher input data rates. The TLV320AIC3262 DAC channel includes a built-in digital interpolation filter to generate oversampled data for the sigma-delta modulator. The interpolation filter can be chosen from three different types depending on required frequency response, group delay and sampling rate.

Powertune The TLV320AIC3262 features PowerTune, a mechanism to balance power-versus-performance trade-offs at the time of device configuration. The device can be tuned to minimize power dissipation, to maximize performance, or to an operating point between the two extremes to best fit the application. The TLV320AIC3262 PowerTune modes are called PTM_R1 to PTM_R4 for the recording (ADC) path and PTM_P1 to PTM_P4 for the playback (DAC) path. For more detailed information see the Application Reference Guide, SLAU309. Clock Generation and PLL To minimize power consumption, the system ideally provides a master clock that is a suitable integer multiple of the desired sampling frequencies. In such cases, internal dividers can be programmed to set up the required internal clock signals at very low power consumption. For cases where such master clocks are not available, the built-in PLL can be used to generate a clock signal that serves as an internal master clock. In fact, this master clock can also be routed to an output pin and may be used elsewhere in the system. The clock system is flexible enough that it even allows the internal clocks to be derived directly from an external clock source, while the PLL is used to generate some other clock that is only used outside the TLV320AIC3262. 46 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): TLV320AIC3262 TLV320AIC3262 www.ti.com SLAS679 – DECEMBER 2011 The TLV320AIC3262 supports a wide range of options for generating clocks for the ADC and DAC sections as well as interface and other control blocks. The clocks for ADC and DAC require source reference clocks, and these clocks can be from a single source or from two separate sources. They can be provided on a variety of device pins such as MCLKx, BCLK1, BCLK2, GPI1, GPI2, or GPIOx pins. The clocks, ADC_CLKIN and DAC_CLKIN, can then be routed through highly-flexible clock dividers to generate the various clocks required for ADC, DAC and the miniDSP sections. In the event that the desired audio or miniDSP clocks cannot be generated from the reference clocks on MCLKx, BCLK1, BCLK2, or GPIOx, the codec also provides the option of using the on-chip PLL which supports a wide range of fractional multiplication values to generate the required clocks. The ADC_CLKIN and DAC_CLKIN can then be routed through highly-flexible clock dividers to generate the various clocks required for ADC, DAC and the miniDSP sections.

For SPI, SPI_SELECT should be tied high; for I2C, SPI_SELECT should be tied low. It is not recommended to change the state of SPI_SELECT during device operation. I2C Control The TLV320AIC3262 supports the I2C control protocol, and will respond by default (GPI3 and GPI4 grounded) to the 7-bit I2C address of 0011000. With the two I2C address pins, GPI3 and GPI4, the device can be configured to respond to one of four 7-bit I2C addresses, 0011000, 0011001, 0011010, or 0011011. The full 8-bit I2C address can be calculated as: 8-Bit I2C Address = "00110" + GPI4 + GPI3 + R/W E.g. to write to the TLV320AIC3262 with GPI4 = 1 and GPI3 = 0 the 8-Bit I2C Address is "00110" + GPI4 + GPI3 + R/W = "00110100" = 0x34 I2C is a two-wire, open-drain interface supporting multiple devices and masters on a single bus. Devices on the I2C bus only drive the bus lines LOW by connecting them to ground; they never drive the bus lines HIGH. Instead, the bus wires are pulled HIGH by pullup resistors, so the bus wires are HIGH when no device is driving them LOW. This way, two devices cannot conflict; if two devices drive the bus simultaneously, there is no driver contention. SPI Control In the SPI control mode, the TLV320AIC3262 uses the pins SCL as SS, GPI1 as SCLK, GPO1 as MISO, SDA as MOSI; a standard SPI port with clock polarity setting of 0 (typical microprocessor SPI control bit CPOL = 0) and clock phase setting of 1 (typical microprocessor SPI control bit CPHA = 1). The SPI port allows full-duplex, synchronous, serial communication between a host processor (the master) and peripheral devices (slaves). The SPI master (in this case, the host processor) generates the synchronizing clock (driven onto SCLK) and initiates transmissions. The SPI slave devices (such as the TLV320AIC3262) depend on a master to start and synchronize transmissions. A transmission begins when initiated by an SPI master. The byte from the SPI master begins shifting in on the slave MOSI pin under the control of the master serial clock (driven onto SCLK). As the byte shifts in on the MOSI pin, a byte shifts out on the MISO pin to the master shift register. For more detailed information see the Application Reference Guide, SLAU309. Digital Audio Interfaces The TLV320AIC3262 features three digital audio data serial interfaces, or audio buses. These three interfaces can be run simultaneously, thereby enabling reception and transmission of digital audio from/to three separate devices. A common example of this scenario would be individual connections to an application processor, a communication baseband processor, and a Bluetooth chipset. By utilizing the TLV320AIC3262 as the center of the audio processing in a portable audio system, mixing of voice and music audio is greatly simplified. In addition, the miniDSP can be utilized to greatly enhance the portable device experience by providing advanced audio processing to both communication and media audio streams simultaneously. In addition to the three simultaneous digital audio interfaces, a fourth set of digital audio pins can be muxed into Audio Serial Interface #1. In other words, four separate 4-wire digital audio buses can be connected to the TLV320AIC3262, with up to three of these 4-wire buses receiving and sending digital audio data. 48 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): TLV320AIC3262 TLV320AIC3262 www.ti.com SLAS679 – DECEMBER 2011 Audio Serial Interfaces BCLK BCLK3 DIN DOUT DOUT3 WCLK DIN3 DOUT WCLK3 AUDIO SERIAL INTERFACE #3 DOUT2 DIN DIN2 BCLK BCLK2 WCLK2 WCLK GPIO1 DOUT AUDIO SERIAL INTERFACE #2 GPIO2 GPI2 GPO1 DIN DOUT1 BCLK BCLK1 WCLK1 WCLK DIN1 AUDIO SERIAL INTERFACE #1 Figure 25. Typical Multiple Connections to Three Audio Serial Interfaces Each audio bus on the TLV320AIC3262 is very flexible, including left or right-justified data options, support for I2S or PCM protocols, programmable data length options, a TDM mode for multichannel operation, very flexible master/slave configurability for each bus clock line, and the ability to communicate with multiple devices within a system directly. Each of the three audio buses of the TLV320AIC3262 can be configured for left or right-justified, I2S, DSP, or TDM modes of operation, where communication with standard telephony PCM interfaces is supported within the TDM mode. These modes are all MSB-first, with data width programmable as 16, 20, 24, or 32 bits. In addition, the word clock and bit clock can be independently configured in either Master or Slave mode, for flexible connectivity to a wide variety of processors. The word clock is used to define the beginning of a frame, and may be programmed as either a pulse or a square-wave signal. The frequency of this clock corresponds to the maximum of the selected ADC and DAC sampling frequencies. When configuring an audio interface for six-wire mode, the ADC and DAC paths can operate based on separate word clocks. The bit clock is used to clock in and clock out the digital audio data across the serial bus. When in Master mode, this signal can be programmed to generate variable clock pulses by controlling the bit-clock divider. The number of bit-clock pulses in a frame may need adjustment to accommodate various word-lengths as well as to support the case when multiple TLV320AIC3262s may share the same audio bus. When configuring an audio interface for six-wire mode, the ADC and DAC paths can operate based on separate bit clocks. The TLV320AIC3262 also includes a feature to offset the position of start of data transfer with respect to the word-clock. This offset can be controlled in terms of number of bit-clocks. The TLV320AIC3262 also has the feature of inverting the polarity of the bit-clock used for transferring the audio data as compared to the default clock polarity used. This feature can be used independently of the mode of audio interface chosen. The TLV320AIC3262 further includes programmability to 3-state the DOUT line during all bit clocks when valid data is not being sent. By combining this capability with the ability to program at what bit clock in a frame the audio data begins, time-division multiplexing (TDM) can be accomplished, enabling the use of multiple codecs on a single audio serial data bus. When the audio serial data bus is powered down while configured in master mode, the pins associated with the interface are put into a 3-state output condition. By default, when the word-clocks and bit-clocks are generated by the TLV320AIC3262, these clocks are active only when the codec (ADC, DAC or both) are powered up within the device. This is done to save power. However, it also supports a feature when both the word clocks and bit-clocks can be active even when the codec in the device is powered down. This is useful when using the TDM mode with multiple codecs on the same bus, or when word-clock or bit-clocks are used in the system as general-purpose clocks.

The first miniDSP core is tightly coupled to the ADC, the second miniDSP core is tightly coupled to the DAC. The algorithms for the miniDSP must be loaded into the device after power up. The miniDSPs have direct access to the digital stereo audio stream on the ADC and on the DAC side, offering the possibility for advanced, very-low group delay DSP algorithms. Each miniDSP can run up to 1145 instructions on every audio sample at a 48kHz sample rate. The two cores can run fully synchronized and can exchange data. The TLV320AIC3262 features the ability to process a multitude of algorithms simultaneously. For example, the miniDSPs enable simultaneous noise cancellation, acoustic echo cancellation, sidetone, equalization filtering, dynamic range compression, conversation recording, user-interface sound mixing, and other voice enhancement processing at voice-band sampling rates (e.g. 8kHz) and highdefintion voice sampling rates (e.g. 16kHz). The TLV320AIC3262 miniDSPs also enable advanced DSP sound enhancement algorithms for an enhanced media experience on a portable audio device. Software Software development for the TLV320AIC3262 is supported through TI's comprehensive PurePath Studio Development Environment. A powerful, easy-to-use tool designed specifically to simplify software development on the TLV320AIC3xxx miniDSP audio platform. The Graphical Development Environment consists of a library of common audio functions that can be dragged-and-dropped into an audio signal flow and graphically connected together. The DSP code can then be assembled from the graphical signal flow with the click of a mouse. For more detailed information see the Application Reference Guide, SLAU309. Asynchronous Sample Rate Conversion (ASRC) For playing back audio/speech signals at various sampling rates, AIC3262 provides an efficient asynchronous sampling rate conversion with the combination of a dedicated ASRC coefficient calculator and the DAC miniDSP engine. The coefficient calculator estimates the audio/speech data input rate versus the DAC playback rate and feeds the calculated coefficients to the miniDSP, with which it converts the audio/speech data to the DAC playback rate. The whole process can be configured automatically without the need of any input sampling rate related information. The input sampling rates as well as the DAC playback rate are not limited to the typical audio/speech sampling rates. A reliable and efficient handshaking is involved between the miniDSP software and the coefficient calculator. For detailed information, please refer to the AIC3262 software programming manual. For more detailed information see the Application Reference Guide, SLAU309. Power Supply The TLV320AIC3262 integrates a large amount of digital and analog functionality, and each of these blocks can be powered separately to enable the system to select appropriate power supplies for desired performance and power consumption. The device has separate power domains for digital IO, digital core, analog core, analog input, receiver driver, charge-pump input, headphone driver, and speaker drivers. If desired, all of the supplies (except for the supplies for speaker drivers, which can directly connect to the battery) can be connected together and be supplied from one source in the range of 1.65 to 1.95V. Individually, the IOVDD voltage can be supplied in the range of 1.1V to 3.6V. For improved power efficiency, the digital core power supply can range from 1.26V to 1.95V. The analog core voltages (AVDD1_18, AVDD2_18, AVDD4_18, and AVDD_18) can range from 1.5V to 1.95V. The microphone bias (AVDD3_33) and receiver driver supply (RECVDD_33) voltages can range from 1.65V to 3.6V. The charge-pump input voltage (CPVDD_18) can range from 1.26V to 1.95V, and the headphone driver supply (HVDD_18) voltage can range from 1.5V to 1.95V. The speaker driver voltages (SLVDD, SRVDD, and SPK_V) can range from 2.7V to 5.5V. For more detailed information see the Application Reference Guide, SLAU309.
