Product introduction:
CM102-A/102s+ series is a highly integrated single- chip USB stereo speaker application. Minimum external components are required to build a USB speaker system, which makes the CM102-A/102s+ an easy and very cost-effective solution. Because no driver is necessary. Audio playback of all major operational exercises. The CM102-A+/102s+ offers a true plug-and-play feature for external digital audio playback.
CM102-A+/102s+ is supported for power saving USB suspend mode and resume. With power amplifier enable pins and volume control VR input pins, conventional speaker front panel designs can be built. This new single chip supports not only 44.1khz and 48khz sample rate playback but also high frequency light quality with X2 modulation. even better is. The simplified anti-pop noise decapsulation scheme is a general pop noise problem for embedded chips. All functions are certified by UDB if program. More flexible and custom designs are possible with GPIO pins that can make specific requests over USB. This chip
solution not only embeds USB transceiver, ADC, DAC components but also integrates digitally controlled power amplifier functions for USB digital sound applications. The dynamic range control function can support the ability of high-efficiency volume output to obtain a loudness sound similar to that of a class-D amplifier. Vending machines can use microcontrollers to save on external amplifier components and get a better listening experience when listening to music sources with a wide dynamic range. Product advantages: 1. 2CH DAC and class AB amplifier 2. Synchronized digital volume control with PC or laptop 3. Digital audio signal reduces analog noise 4. Portable plug and play through a single USB plug 5. Power adapter unified with USB interface take point
Product Features:
1. USB 2.0 Full Speed Compatible and USB IF Certified
2. USB Audio Device Class Specification v1.0 Compliant
3. USB Bus Powered 500mA Operation Suspend Mode Support
4. USB Audio Function Topology has 1 input terminal, 1 output terminal, and 1 functional unit
5. Embedded high performance 16-bit stereo audio DAC
6. Embedded digitally controlled power amplifier and speaker driver
7. Embedded power-on reset block and power amplifier enable/disable control pin
8. Embedded X2 Adjusted for higher audio quality
9. Embedded anti-pop circuit with internal feedback structure
10. Embedded 5V and 3.3V regulators with voltage level detectors for single 5V external power supply
alternatives Active operation
11. Single 12mhz crystal input with on-chip PLL and embedded USB transceiver
supports Dynamic Range Control (DRC) function to provide a better listening experience
12. Volume control input with simple external VR circuit
13. Isochronous transfer using adaptive synchronization with internal
PLL Usage 17. Support S/PDIF output interface 18. LED indicator pin during playback
19. 兼容98se/赢我赢/赢/赢2000XP/Vista,Mac OS X 没有额外的驱动程序
20. 紧凑的18针PDIP和SOP包
软件选项：
1. 单独为每个扬声器音量控制
2. 环境音效
3. 议长移器
4. 房间大小模式
5. 图示均衡器
