The CS53L30-CWZR is an ultra low power, high performance, quad-channel A/D converter designed to enhanced voice processing features such as noise suppression, acoustic echo cancellation and multi-channel beamforming and offer improved performance in voice capture processing such as voice control and recognition. A flexible input front end supports up to four line/analog mic or four digital mic (DMIC) channels with two digital mic serial clock outputs. Up to four CS53L30-CWZR ICs can be configured to output up to 16 channels of data over a single TDM line for seamless system integration. With less than 2.5 mW of power consumption per channel, the CS53L30-CWZR is a targeted fit for smartphones, tablets and other consumer electronics applications.
