The Conexant CX20787 is an ultra low-power, I2S 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 an ideal turnkey solution for applications that require high-quality audio performance such as tablets, ultrabooks, portable media players, and smartphones. The CX20787 satisfies the demand for high-quality audio in these devices while consuming very little power, thus helping to preserve battery life.The Conexant CX20452 Handset Codec is an Integrated Analog (IA) circuit providing modem digital-to-analog and analog-to-digital conversion. It is packaged in a 24-pin QFN. The CX20452 Codec can serve as a line interface device between a Conexant Modem Data Pump (MDP) and the PSTN. It can also serve as a voice interface between the MDP and a microphone and speaker. The MDP communicates with the CX20452 Codec via a serial interface.
Featuring integrated digital signal processing (DSP), fully configurable hardware EQ and dual-knee dynamic range control (DRC) with reconfigurable inputs or outputs, the CX20787 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.
