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.
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.
“Long battery life, small footprint and low cost, along with superior audio fidelity, are absolute must-haves to win in the portable market,” said Jonathan Chien, executive director of marketing for Conexant. “With the introduction of the CX20787, we are providing an optimum solution with ultra low-power and a superior audio experience, paired with our renowned voice processing algorithms, while enabling our customers to save on bill of materials costs.”
