DESCRIPTION
The WM8803 is a digital audio interface receiver conforming
to IEC 60958/61937 and EIAJ CP-1201. It supports input
audio data rates up to 192kHz and a maximum output data
length of 24 bits.
The WM8803 has a flexible digital output port that allows the
user access to channel status pre-emphasis information, input
signal sampling frequency, sub-code Q data with the
associated CRC flags and other status data.
The WM8803 can output an externally input clock signal that
can be used as an ADC converter clock when the PLL is
unlocked. It also maintains the continuity of the output clock
when the clock is switched.
The WM8803 includes a built-in oscillator and serial data
input circuits and allows the system micro-controller to read
the sub-code Q data and the channel status. It provides
several low-power modes, thus supporting applications that
require long battery life, such as portable audio devices and
PDAs.
The device is available in a 24-pin TSSOP package.
