CM6533,CM6533N,CM6533X1,CM6533DH
USB Audio Chip
 Single 5V power supply (embedded 5V to 1.8V regulator for digital core, 5V to 3.3V regulator for digital IO, 5V to
3.6V regulator for analog codec)
 3.3V digital I/O pads with 5V tolerance
 Industrial standard LQFP-48 package (7x7mm)
2.5 Audio I/O
 Playback Stream:
 Speaker/Headphone
 Sample Rates: 8K/11.025K/16K/22.05K/32K/44.1K/48K/88.2K/96KHz
 Supports Bit Length: 16/24bits
 Speaker Gain Range (Analog) is -44 ~ 0dB, 1dB/step
 DAC Gain Range (Digital) is -62 ~ 0dB, 1dB/step
 S/PDIF transmitter
 Sample Rates: 44.1K/48K/88.2K/96KHz
 Supports Bit Length: 16/24 bits
 Recording Stream:
 Microphone
 Sample Rates: 8K/11.025K/16K/22.05K/32K/44.1K/48K/96KHz
 Supports Bit Length: 16/24 bits
 Microphone gain range (Analog) is -18 ~ 45dB, 1dB/step
 ADC gain range (Digital) is -16 ~ 12dB, 1dB/step
 Stereo Mixer
 Mix stereo playback stream and stereo microphone
 Stereo Mixer gain range is -30 ~ 33dB, 1dB/step
 A-A path Stream:
 Microphone to playback A-A path
 Mix mono microphone input to stereo playback both L/R channel
 The Microphone A-A path gain range is -15 ~ 32dB, 1dB/step
**Note 1: A-A path means Analog to Analog Mixer path
**Note 2:
CM6533/CM6533N/CM6533X1/CM6533DH is a USB 2.0 Full Speed audio device. Since bandwidth limitation,
CM6533/CM6533N/CM6533X1/CM6533DH cannot support 96KHz/24bits for playback and capture streams
simultaneously. The possible combinations are shown below:
Playback
