CM7037
INTRODUCTION

The CM7037 is a S/PDIF in receiver to convert the audio data to I2S and analog out. The input audio format of SPDIF in signal can be detected automatically and convert to I2S and analog out. The CM7037 only supports standard IEC60958, PCM Audio data. If the data is non PCM, there will be no output for the I2S and analog out.
