概览
安森美半导体的 Rhythm™SB3229 混合动力系统是基于具有反馈消除算法的四沟道压缩电路的可微调配置 DSP 系统。 Rhythm SB3229 基于相位抵消方法，其自适应反馈减少算法可提供增加的稳定增益，以实现额外增益和用户舒适度。它具有针对动态反馈情况的快速调整功能和音调输入电阻。 除这些自适应算法外，Rhythm SB3229 还支持以下功能：多达四个沟道 WDRC、低失真压缩限制、音频路径之间的交叉渐变（用于无点击内存更改）、八频段图形均衡器、八个可配置的通用双二阶滤波器、编程速度增强、通道内静音衰减麦克风和安静环境中的电路噪声、可选峰值削波、灵活压缩调整、音量控制、翘板开关、耳鸣治疗产生的噪声、可避免克隆和软件盗版的业界领先安全功能。 微调器接口支持手动电路配置。它可持续监控微调器的位置，并将其转换为所选的助听器参数。串行数据或 I²C 接口可在工厂和现场提供全面可编程性。 Rhythm SB3229 混合器件包含一个用于可编程和微调器件的 256 kB EEPROM。软件 SupportARK 是一组软件构造块，有助于缩短开发助听器安装软件所需的时间。ARKonline 是一款基于 Web 的高效工具，用于创建产品库和保持它们的有序组织形式。要访问 ARKonline，请转至 www.onsemi.com/arkonline.
