低成本免调模拟轮调收音芯片在多波段收音机的应用
近年来,基于 DSP 技术的收音机通过 LCD/LED 频率显示和自动搜索频率按键吸引了众多消费者。然而,尽管许多收音机用户体会到 LCD 或 LED 面板显示频率所带来的便利,但是比起那些调频的按键来,他们还是更喜欢使用直观的调谐滚轮(如图 1 所示)。 为了简便,我们将其称之为“轮调”收音机,即“模拟调谐”收音机。
图 1:模拟调谐收音机
世强代理的SILICON LABS新一代低成本的免调(不需校准)模拟轮调收音芯片Si4825,其架构如下图2所示:芯片通过Tune1的稳压输出与Tune2的PVR电位器分压的比例来计算谐调的频率。由于芯片内部采用数字调谐无需外部可调元件,完全避免了传统模拟芯片多个外部可调电感、电容的一致性和劳动力,降低了生产的工人成本以及生产中反工及出货后退货风险。

同时芯片内部分通过专利算法来优化模拟传统收音机的调台手感,如图3所示Si4825可以在目标频点一定范围内抓到信号,并根据当前频点与实际频点的偏差给出音频输出幅度衰减、立体声指示(Si4836支持立体声),以区别是准确锁定节目。

波段选择:
通过BAND的分压电阻网来设置不同波段—芯片内部预设的波段。这些电阻均需要采用1%精度的精密电阻,否则会影响波段设置的准确性。其中从Tune1到GND的总电阻为500K,不同波段对应不同的BAND到GND电阻值。详细的预设波段划分可向世强索取 Si4825 天线、原理图、布局和设计指南。
宽调频宽短波设计:
通常的模调收音机都是多波段收音机,其中FM调频和SW短波都有多个波段设置,而部分简单的收音机如闹钟收音机或者功能较多的收音只是其中部分功能的产品,往往希望尽量少的波段来覆盖全部接收范围。通常FM调频波段一般宽度为20MHz,SW波段则一般只有不到1.5MHz.而Si4825 FM调频可以最大覆盖64~108MHz全波段,SW短波最大一个波段可以覆盖13MHz的带宽。
Si4825支持宽短波与窄短波两种模式,这两种模式通过外部引脚1脚上下/下拉电阻设置来选择的。如下图4所示,当芯片引脚1上拉10K电阻到电源时选择为宽短波模式,当引脚1悬空时选择窄短波模式,因为芯片内部有50K下拉电阻所以外部下拉电阻省略。

【经验】实现FM/AM/SW模调接收器Si4825音量键控功能的方法分享
Silicon Labs的FM/AM/SW模调接收器Si4825芯片以稳定的性能,简单的外围电路设计等优势,在初级消费类产品市场应用非常广泛。由于之前的收音机设计中普遍使用后级功放来控制音量大小,所以很多客户在应用Si4825的过程中提到Si4825音量键控功能不知道该怎么实现,有些客户做出来的产品键控功能不正常不能实现想要的键控效果。本文就说明Si4825音量键控功能的实现。
