WM8803数据手册CirrusLogic中文资料规格书

描述 Description

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.FEATURES
