Video Proc 100-Pin LQFP Tray

The ZL38004 is a hardware platform designed to support advanced acoustic echo canceller (with noise reduction) firmware applications available from Microsemi. These applications are resident in external memory and are downloaded by the ZL38004 resident boot code during initialization. The DSP Core can process up to four 8-bit audio channels, two 16-bit audio channels or two 8-bit and one 16-bit audio channel. These audio channels may originate and terminate with the ?? CODECs, or be communicated to and from the DSP Core through the PCM ports or the I²S port.
