Hot selling Original stock sale CM6542 USB (Type-C) Ultra-low-power Audio Single Chip Datasheet v1.9 QFN48
CM6542 is an RGB lighting effect, Ultra low power/True Capss HP Driver USB-C audio chip
Product Descriptions
The CM6542 is the new generation ultra-low-power USB audio single chip designed especially for mobile USB-C headset, audio adapter or dock applications. It features cap-less/anti-pop headphone driver, combo-jack swap & jack-detection, Google buttons detection, embedded oscillator, flash, tri-color LED PWM driver, Digital EQ, DC-DC converter, etc., which can fulfill cost-effective, low-power, and versatile USB Type-C Audio accessories in a concise design for Android smartphones, tablets, New iPad Pro(2018), and PC. It also supports automatic power-down and active modes switch when the 3.5mm headset is unplugged or plugged-in to save the power consumption in USB-C audio adapter/dongle applications. Besides, it has Google headset 4-button in-line control detection and CTIA/OMTP typed headset/headphone auto switch. The integrated digital EQ and tri-color LED driver can bring more differentiation to the USB-C audio accessories. Up-to -96KHz/24bit codec support can facilitate Hi-Res Audio products.
