APPLICATION DESCRIPTIONS Sampling Rate and Input Clocks The serial audio input data is transmitted to the device at SDATA pin. According to the sampling rate, the device can work in three speed modes, single speed, double speed and quad speed. The device can detect the speed mode of the input data stream automatically when the sampling rate falls into the auto detection ranges listed in Table1. If the sampling rate is outside the auto detection ranges, the device will not work properly. Table 1 Auto Detection Ranges and CLKIN/LRCK Ratio. MODE Fs Auto Detection Range CLKIN/LRCK Ratio Single Speed 8kHz – 50kHz 256, 384, 512, 768, 1024 Double Speed 84kHz – 100kHz 128, 192, 256, 384, 512 Quad Speed 167kHz – 200kHz 128, 192, 256 The device works with the input system clock CLKIN, sample data clock LRCK and bit clock SCLK. The data clock and bit clock must be synchronously derived from the system clock with some specific rates. The device only supports the CLKIN/LRCK ratios listed in Table1. The LRCK/SCLK ratio is normally 64. The device detects clock ratios automatically, and it will not work properly if any ratio is incorrect. Audio Data Input The PA5144LV can accept I²S serial audio input data from 16-bit to 24-bit. The device can detect the data word length automatically. The relationship of SDATA, SCLK and LRCK for the format is illustrated through Figures 2. 1 SCLK SDATA 1 2 1 SCLK 3 n- 2 n- 1 MSB n 1 LSB MSB 2 3 n- 2 n- 1 n LSB SCLK LRCK LEFT CHANNEL RIGHT CHANNEL 2 Figure 2.

During this state, the device clamps outputs to ground and power down the device operation except for clock management unit. Once proper CLKIN and LRCK clocks are applied, the device will leave power down state, and the device outputs ramp from ground to common mode voltage softly. Then the device enters the normal operation. 561 E. Elliot Road #175 Chandler, AZ 85225 Tel: (480) 539-2900.
