Product Summary

The MSP4450K-VK-E8-000T is a Multistandard Sound Processor. The device is designed for the usage in hybrid set-top boxes and multimedia applications. Its asynchronous I2S slave interface allows the reception of digital stereo signals with arbitrary sample rates ranging from 5 to 50kHz. Synchronization is performed by means of an adaptive sample rate converter. The MSP4450K-VK-E8-000T offers the full audio bandwidth of 20 kHz and the backend DSP processing is performed at a 48 kHz sample rate.
