USB Headphone Control IC Chip solution development
NX4088 is a highly integrated USB/YTPE-C audio chip. Embedded all necessary analog modules, including dual DAC and audio driver, microphone amplifier, PLL, voltage regulator, and USB transceiver. In addition, the audio volume can be easily adjusted through dedicated HID compatible volume control pins.
Features
1.Support for USB2.0; TYPE-C. 24 pin SSOP24 package 2.Supports functions such as button sound addition and subtraction, muting, and microphone silencing 3.Supports USB pause/resume mode and remote wake-up function for volume control pins 4.Speaker mode (only with playback function) or headphone mode (playback+recording) has jumper pins 5.In headphone mode, turn on/off the mixer unit through the jumper pin
6.Supports one control terminal, one synchronous output terminal, one synchronous input terminal, and one interrupt terminal
7.When the device pauses, set the Releasing Playback Bandwidth and USB bus alternately to zero bandwidth
8.The mute indication pin uses LED to indicate the mute status.
9.The earpiece amplifier is an embedded high-performance 16 bit audio DAC, and the microphone amplifier input is a 16 bit embedded ADC
10.Embedded Power On Reset module, embedded 5V-3.3V voltage regulator supports single external 5V operation
