Ultra Low Power, 4-Channel Microphone A/D Converter With TDM Interface
The CS53L30 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 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 is a targeted fit for smartphones, tablets and other consumer electronics applications.
