Description
The SPCA751A is a single chip signal processor optimized for MPEG audio decoding and voice recording. It is developed to achieve a better performance/cost ratio for MPEG audio players. The SPCA751A is especially designed for standalone audio players, the system controller can easily carry out the MPEG audio decoding process by the use of a general serial IO/control interface for MPEG bit stream in/out and playback control. Decoded audio PCM data are output to external DAC through a programmable normal/I2S DAC interface, such that most of common audio DACs can be cooperated with SPCA751A to meet different customers requirements.
