Echo Canceler Drops Cost And Power Use

The MT93L16 is a low-voltage acoustic echo canceler for a wide range of telephony applications. It's based on the firm's TRUEPLEX technology, which is said to provide enhanced audio while reducing costs by up to 33% and power usage by up to 78% compared with alternative microprocessor solutions. The full-duplex device operates from 3.3V and offers 5V-tolerant I/Os. It draws just 65 mW.TRUEPLEX technology eliminates residual echoes without removing near-end signals or background room noise. It's said to provide extremely high voice quality even when long delays are introduced.
