TAS5711 www.ti.com SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 DETAILED DESCRIPTION POWER SUPPLY To facilitate system design, the TAS5711 needs only a 3.3-V supply in addition to the (typical) 18-V power-stage supply. An internal voltage regulator provides suitable voltage levels for the gate drive circuitry. Additionally, all circuitry requiring a floating voltage supply, e.g., the high-side gate drive, is accommodated by built-in bootstrap circuitry requiring only a few external capacitors.

TAS5711 www.ti.com SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 CLOCK, AUTO DETECTION, AND PLL The TAS5711 is a slave device. It accepts MCLK, SCLK, and LRCLK. The digital audio processor (DAP) supports all the sample rates and MCLK rates that are defined in the clock control register . The TAS5711 checks to verify that SCLK is a specific value of 32 fS, 48 fS, or 64 fS. The DAP only supports a 1 × fS LRCLK. The timing relationship of these clocks to SDIN is shown in subsequent sections.

A bit clock running at 32, 48, or 64 × fS is used to clock in the data. The first bit of data appears on the data 8 bit-clock periods (for 24-bit data) after LRCLK toggles. In RJ mode the LSB of data is always clocked by the last bit clock before LRCLK transitions. The data is written MSB first and is valid on the rising edge of bit clock.

TAS5711 www.ti.com SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 I2C SERIAL CONTROL INTERFACE The TAS5711 DAP has a bidirectional I2C interface that compatible with the I2C (Inter IC) bus protocol and supports both 100-kHz and 400-kHz data transfer rates for single and multiple byte write and read operations. This is a slave only device that does not support a multimaster bus environment or wait state insertion.
TAS5711 SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 www.ti.com During multiple-byte read operations, the DAP responds with data, a byte at a time, starting at the subaddress assigned, as long as the master device continues to respond with acknowledges. If a particular subaddress does not contain 32 bits, the unused bits are read as logic 0. During multiple-byte write operations, the DAP compares the number of bytes transmitted to the number of bytes that are required for each specific subaddress.
TAS5711 www.ti.com SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 Single-Byte Read As shown in Figure 49, a single-byte data read transfer begins with the master device transmitting a start condition followed by the I2C device address and the read/write bit. For the data read transfer, both a write followed by a read are actually done. Initially, a write is done to transfer the address byte or bytes of the internal memory address to be read. As a result, the read/write bit becomes a 0.

There is one ganged DRC for the left/right channels and one DRC for the subchannel. The DRC input/output diagram is shown in Figure 52. Refer to GDE software tool for more description on T, K, and O parameters.
TAS5711 SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 www.ti.com BANK SWITCHING The TAS5711 uses an approach called bank switching together with automatic sample-rate detection. All processing features that must be changed for different sample rates are stored internally in three banks. The user can program which sample rates map to each bank. By default, bank 1 is used in 32kHz mode, bank 2 is used in 44.1/48 kHz mode, and bank 3 is used for all other rates.
TAS5711 www.ti.com SLOS600A – DECEMBER 2009 – REVISED AUGUST 2010 The decimal value of a 3.23 format number can be found by following the weighting shown in Figure 54. If the most significant bit is logic 0, the number is a positive number, and the weighting shown yields the correct number. If the most significant bit is a logic 1, then the number is a negative number.

The clock control register contains the auto-detected clock status. Bits D7–D5 reflect the sample rate. Bits D4–D2 reflect the MCLK frequency. The device accepts a 64 fS or 32 fS SCLK rate for all MCLK ratios, but accepts a 48 fS SCLK rate for MCLK ratios of 192 fS and 384 fS only. Table 5.
