8.4.1 TDM Port

The TAS2562 provides a flexible TDM serial audio port. The port can be configured to support a variety of formats including stereo I2S, Left Justified and TDM. Mono audio playback is available via the SDIN pin. The SDOUT pin is used to transmit sample streams including speaker voltage and current sense, VBAT voltage, die temperature and channel gain.

The TDM serial audio port supports up to 16 32-bit time slots at 44.1/48 kHz, 8 32-bit time slots at a 88.2/96 kHz sample rate and 4 32-bit time slots at a 176.4/192 kHz sample rate. The device supports 2 time slots at 32 bits in width and 4 or 8 time slots at 16, 24 or 32 bits in width. Valid SBCLK to FSYNC ratios are 64, 96, 128, 192, 256, 384 and 512. The device will automatically detect the number of time slots and this does not need to be programmed.

By default, the TAS2562 will automatically detect the PCM playback sample rate. This can be disabled by setting the AUTO_RATE register bit high and manually configuring the device.

The SAMP_RATE[2:0] register bits set the PCM audio sample rate when AUTO_RATE is enabled. The TAS2562 employs a robust clock fault detection engine that will automatically volume ramp down the playback path if FSYNC does not match the configured sample rate (AUTO_RATE enabled) or the ratio of SBCLK to FSYNC is not supported (minimizing any audible artifacts). Once the clocks are detected to be valid in both frequency and ratio, the device will automatically volume ramp the playback path back to the configured volume and resume playback.

When using the auto rate detection the sampling rate and SBCLK to FSYNC ration detected on the TDM bus is reported back on the read-only register FS_RATE and FS_RATIO respectively.

While the sampling rate of 192kHz is supported, it is internally down-sampled to 96kHz. Therefore audio content greater than 40kHz should not be applied to prevent aliasing. This additionally effects all processing blocks like BOP and limiter which should use 96kHz fs when accepting 192 kHz audio. It is recommend to use PurePath™ Console 3 Software to configure the device.

Figure 56 and Figure 57 below illustrates the receiver frame parameters required to configure the port for playback. A frame begins with the transition of FSYNC from either high to low or low to high (set by the FRAME_START register bit). FSYNC and SDIN are sampled by SBCLK using either the rising or falling edge (set by the RX_EDGE register bit). The RX_OFFSET[4:0] register bits define the number of SBCLK cycles from the transition of FSYNC until the beginning of time slot 0. This is typically set to a value of 0 for Left Justified format and 1 for an I2S format.

The RX_SLEN[1:0] register bits set the length of the RX time slot. The length of the audio sample word within the time slot is configured by the RX_WLEN[1:0] register bits. The RX port will left justify the audio sample within the time slot by default, but this can be changed to right justification via the RX_JUSTIFY register bit. The TAS2562 supports mono and stereo down mix playback ([L+R]/2) via the left time slot, right time slot and time slot configuration register bits (RX_SLOT_L[3:0], RX_SLOT_R[3:0] and RX_SCFG[1:0] respectively). By default the device will playback mono from the time slot equal to the I2C base address offset for playback. The RX_SCFG[1:0] register bits can be used to override the playback source to the left time slot, right time slot or stereo down mix set by the RX_SLOT_L[3:0] and RX_SLOT_R[3:0] register bits.

If time slot selections places reception either partially or fully beyond the frame boundary, the receiver will return a null sample equivalent to a digitally muted sample.

The TDM port can transmit a number sample streams on the SDOUT pin including speaker voltage sense, speaker current sense, VBAT voltage, die temperature and channel gain. Figure 58 below illustrates the alignment of time slots to the beginning of a frame and how a given sample stream is mapped to time slots. Either the rising or falling edge of SBCLK can be used to transmit data on the SDOUT pin, which can be configured by setting the TX_EDGE register bit. The TX_OFFSET register defines the number SBCLK cycles between the start of a frame and the beginning of time slot 0. This would typically be programmed to 0 for Left Justified format and 1 for I2S format. The TDM TX can either transmit logic 0 or Hi-Z depending on the setting of the TX_FILL register bit setting. An optional bus keeper will weakly hold the state of SDOUT when all devices driving are Hi-Z. Since only one bus keeper is required on SDOUT, this feature can be disabled via the TX_KEEPEN register bit. The bus-keeper can additionally be configured to be enabled for only 1LSB cycle or always using TX_KEEPLN and to drive the full or half cycle of the LSB using TX_KEEPCY.

Each sample stream is composed of either one or two 8-bit time slots. , so they will always utilize two TX time slots. The VBAT voltage stream is 10-bit precision, and can either be transmitted left justified in a 16-bit word (using two time slots) or can be truncated to 8-bits (the top 8 MSBs) and be transmitted in a single time slot. This is configured by setting VBAT_SLEN register bit. The Die temperature and gain are both 8-bit precision and are transmitted in a single time slot.

The time slot register for each sample stream defines where the MSB transmission begins. For instance, if VSNS_SLOT is set to 2, the upper 8 MSBs will be transmitted in time slot 2 and the lower 8 LSBs will be transmitted in time slot 3. Each sample stream can be individually enabled or disabled. This is useful to manage limited TDM bandwidth since it may not be necessary to transmit all streams for all devices on the bus.

It is important to ensure that time slot assignments for actively transmitted sample streams do not conflict. For instance, if VSNS_SLOT is set to 2 and ISNS_SLOT is set to 3, the lower 8 LSBs of voltage sense will conflict with the upper 8 MSBs of current sense. This will produce unpredictable transmission results in the conflicting bit slots (i.e. the priority is not defined).

The current and voltage values are transmitted at the full 16-bit measured values by default. The IVMON_LEN register can be used to transmit only the 8 MSB bits in one slot or 12 MSB bits values across multiple slots. The special 12-bit mode is used when only 24-bit I2S/TDM data can be processed by the host processor. The device should be configured with the voltage-sense slot and current-sense slot off by 1 slot and will consume 3 consecutive 8-bit slots. In this mode the device will transmit the first 12 MSB bits followed by the second 12 MSB bits specified by the preceding slot.

If time slot selections place transmission beyond the frame boundary, the transmitter will truncate transmission at the frame boundary.

It is recommended to keep the following slot ordering:               

ISNS_SLOT<VSNS_SLOT<VBAT_SLOT<TEMP_SLOT<GAIN_SLOT<BIL_ILIM_SLOT.
