Motorola V998、L2000手机各部分工作原理基本相同。供电电源及音频处理模块主要由一块GCAP*(Audio Interface and Power Control U900)芯片完成,U900是一个多功能的芯片,除为手机供电外,还在U700 OR U800(CPU)控制下,对信号进行无线均衡、信道解码、PCM解码、D/A转换、模拟放大等处理;EPROM和EEPROM主要由一块16 Mbit U701芯片完成;内存储
Motorola V998, L2000 mobile phones basically the same working principle. The power supply and audio processing module is mainly composed of a GCAP * (Audio Interface and Power Control U900) chip. The U900 is a multi-functional chip. Besides the power supply to the handset, the U900 is also under the control of the U700 OR U800 (CPU) Wireless equalization, channel decoding, PCM decoding, D / A conversion, analog amplification and other processing; EPROM and EEPROM mainly by a 16 Mbit U701 chip to complete; memory
