Aimed at the mobile PC market, including notebooks, ultrabooks, and tablets, the CX20752 and CX20754 HD audio codecs integrate a stereo filterless Class D amplifier with patented common-mode scrambling technology capable of driving 2-W rms per channel at 1% THD+N into 4-Ω load. With two 24-bit stereo DACs operating at sampling frequencies up to 192 kHz and two 24-bit stereo ADCs operating at sampling frequencies up to 96 kHz, both codecs can support multistreaming and real-time communications applications.
By combining these hardware features with the company’s proprietary Voice Processing Algorithms, the new codecs offer ideal solutions for platforms needing Microsoft Lync and Skype certification. Additional features include built-in five-band hardware equalizer and dynamic range compression, a ProCoustic capless headphone driver, and PopShield technology which suppresses pops and clicks during all transition states.
Compliant with Intel’s high-definition audio specification 1.1, the CX20752 and CX20754 have audio fidelity exceeding Microsoft WLP 4.0 desktop and notebook premium logo requirements.
Both devices have D-Flex power management that exceeds Intel’s ECR 15B requirements to achieve maximum power savings, while the CX20754 has an added I2 S audio interface for digital docking I/O expansion, digital audio processing, or digital amplifier with external audio devices. (Ea/10,000: CX20752, from $1.24; CX20754, from $1.54 — available now.)
