摘要

介绍了一种用于CT2和CT2+无绳电话的低电压、低功耗CMOS单片基带处理器。该芯片集成了一个完整的语音带编解码器、一个音调发生器、一个G721 AD-PCM编/解码器、一个用于CT2/CT2+帧的突发模式逻辑控制器和一个I/Q基带信号发生器。它可以很容易地通过一个并行接口与标准微控制器接口。它可以在2.7 V的最小电源下运行，工作和待机功耗分别为35 mW和25 /spl mu/W。最大工作电源为5.5 V。在0.8 /spl mu/ N-well CMOS工艺中，芯片面积为55.5 mm/sup 2/。

A 2.7 V CMOS single chip baseband processor for CT2/CT2+ cordless telephones

A low voltage, low power CMOS single chip baseband processor for CT2 and CT2+ cordless telephones is presented. The chip integrates a complete voiceband codec, a tone generator, a G721 AD-PCM coder/decoder, a Burst Mode Logic controller for CT2/CT2+ framings, and an I/Q baseband signal generator. It can be easily interfaced with standard microcontrollers through a parallel interface. It can operate from a 2.7 V minimum supply with operative and stand-by power consumptions of 35 mW and 25 /spl mu/W, respectively. Maximum operative supply is 5.5 V. Chip area is 55.5 mm/sup 2/ in a 0.8 /spl mu/ N-well CMOS process.
