CES: Conexant ultra-lower power I2S audio codec features integrated DSP
CES, Las Vegas -- The CX20787 I2S audio codec from Conexant Systems Inc. is ultra low-power, 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.
The CX20787 features integrated digital signal processing (DSP), fully configurable hardware EQ and dual-knee dynamic range control (DRC) with reconfigurable inputs or outputs. It maximizes speaker loudness without distortion, performs loudness compensation, improves frequency response, protects speakers from over-driving, and extends the microphone pick-up range for far-field speakerphone applications.
The CX20787 has a pair of ProCoustic capless headphone drivers, which eliminate the need for external DC blocking capacitors, and its detect and switch support capabilities support a variety of global headsets. The CX20787 also supports DSP side-port to Conexant’s Digital Audio processor, which adds advanced voice preprocessing and low power Wake-on-Voice function in the portable device.
The CX20787 is currently sampling, and EVKs are available to qualified customers and partners.
