Conexant Unveils Low-Power Audio Codec

Conexant Systems Inc., a semiconductor company headquartered in Newport Beach, Calif., introduces the CX20787, an ultra low-power, audio codec with integrated stereo class-D speaker amplifiers and power-efficient class-G headphone amplifiers.
            When combined with Conexant’s software algorithms and design support, the CX20787, becomes a turnkey solution for applications that require high-quality audio performance such as tablets, ultrabooks, portable media players and smartphones because it requires little battery power, the company says.
            In addition, the CX20787 has integrated digital signal processing, a configurable hardware equalizer and dual-knee dynamic range control with reconfigurable inputs or outputs, Conexant says. It also maximizes speaker loudness without distortion, performs loudness compensation, improves frequency response, protects speakers from over-driving and extends the microphone pick-up range for speakerphone applications.
            It is also equipped with ProCoustic capless headphone drivers, eliminating the need for external DC blocking capacitors. The device’s “detect and switch” support capabilities also support a variety of global headsets, as well as DSP side-port to the company’s digital audio processor, which adds voice preprocessing and low power Wake-on-Voice function, according to Conexant.
