When accessing these addresses, the slice size should be a multiple of 4 bytes and the byte address should be aligned with the 32-bit data word boundaries i.e., an even number . The byte ordering for these register addresses is described in Table Table SLIMbus Register Read/Write Register Space 0x3000 Register Address Base address 0xYYYYZZ Base address + 2 Base address + 4 Base address + 6 Byte Sequence Bytes 4, 3, 2, 1 Bytes 8, 7, 6, 5 Bytes 12, 11, 10, 9 Bytes 16, 15, 14, 13 Output Signal Path The CS42L92 provides four stereo pairs of audio output signal paths. These outputs comprise ground-referenced headphone drivers, and a digital output interface suitable for external speaker drivers. The output signal paths are summarized in Table Table Output Signal Path Summary Signal Path OUT1L, OUT1R OUT2L, OUT2R OUT3L, OUT3R Descriptions Ground-referenced headphone/earpiece output Ground-referenced headphone/earpiece output Ground-referenced headphone/earpiece output OUT5L, OUT5R Digital speaker PDM output Output Pins HPOUT1L, HPOUT1R HPOUT2L, HPOUT2R HPOUT3L, HPOUT3R or HPOUT4L, HPOUT4R SPKDAT, SPKCLK The analog output paths incorporate high performance 32-bit sigma-delta DACs. Under default conditions, the headphone drivers provide a stereo, single-ended output. A mono mode is also supported, providing a differential BTL output configuration. The ground-referenced headphone output paths incorporate a common mode feedback path for rejection of system-related noise. These outputs support direct connection to headphone loads, with no requirement for AC coupling capacitors. The OUT1 and OUT2 paths can be configured in High Performance Mode, offering exceptional performance on the respective headphone outputs. Balanced stereo headphone loads can be supported by assigning the OUT1 and OUT2 signal paths for the left and right channels respectively, with the associated drivers configured for differential output. DS1162F1 CS42L92 Output Signal Path The digital output path provides a stereo pulse-density modulation PDM output interface, for connection to external audio devices. A total of two digital output channels are provided. Digital filters can be enabled in the output signal paths, supporting audiophile-quality DAC playback options. These hi-fi filters allow user selection of the preferred characteristics, e.g., linear phase, antialiasing, or apodizing filter responses . Digital volume control is available on all outputs analog and digital , with programmable ramp control for smooth, glitch-free operation. A configurable noise-gate function is available on each output signal path. Any two of the output signal paths may be selected as input to the AEC loop-back paths. The CS42L92 provides short-circuit detection on the headphone output paths. See Section for further details. The CS42L92 output signal paths are shown in Fig. Note that the OUT4 path is not implemented on this device.
