CM6533-N 数据手册

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

Capture

Stereo, 48kHz/24bits or below

Mono, 96KHz/24bits or below

Stereo, 96KHz/24bits

Audio Format

Stereo, 48kHz/24bits or below

Mono, 96KHz/24bits or below

96KHz/24bits
