方案概述

注：方案交付PCBA/参考设计+主控套料，可接受硬件设计定制。

中国有4亿多家庭，而电视机的数量更要远高于4亿台，其中非智能电视占据着相当大的一部分比例。市场前景巨大且成本低廉的盒子成为互联网企业图谋电视屏的第一选择。因此可以看出机顶盒遥控市场也不会被淘汰，且有着巨大的市场。

客户所使用的全套成品PCBA有以下几个特点：

1. 工作电压：2.5~3.6V

2.待机电流小于10uA；最大发射电流18mA

3.可替代所有红外遥控应用

机顶盒遥控方案概况：

该方案采用2.4G射频无线传输，在接收端保留标准的红外接口（电源、地、data）可按客户要求输出通用如NEC红外码值，最大限度的减小了系统端的匹配问题，是快速替代红外遥控的最优方案。

机顶盒遥控方案特点：

1.   2.4G射频与MCU二合一单芯片设计

2.   遥控端最大支持20个按键

3.   接收端输出标准红外码值

4.   支持单面板设计

5.  可过CE/FCC等标准认证。

本方案支持硬件设计定制及修改建议支持、参考原理图提供、CE/FCC认证技术支持、LAYOUT RVIEW、量产测试支持。

1.  General Description   

 ZS6215A is a high performance and low cost 2.4GHz GFSK system-on-chip(SoC) wireless  transceiver. The embedded baseband protocol engine is based on packet communication and supports various modes from manual operation to advanced autonomous protocol operation. Internal FIFOs ensure a smooth data flow between the radio front end and the system’s MCU. Protocol engine reduces system cost by handling all the high speed link layer operations.    The radio front end uses GFSK modulation. It has user configurable parameter like frequency channel, output power and air rate. It can supports an air data rate of 500Kbps, 1Mbps and 2Mbps. The high air data rate combined with two power saving modes make it suitable for ultralow power designs.
