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.

Quad Speed

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.

Power Up and Power Down
Upon applying VDD, the device will reset itself and enter power down state. 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.
