=== EM4095 === Use in an RFID basestation to perform the following functions: - antenna driving with carrier frequency - AM modulation of the field for writable transponder - AM demodulation of the antenna signal modulation induced by the transponder communicate with a microprocessor via simple interface. '''Features:''' * Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency * No external quartz required *100 to 150 kHz carrier frequency range * Multiple transponder protocol compatibility (e.g. EM400X, EM4050, EM4150, EM4070, EM4170, EM4069) * Sleep mode 1µA * USB compatible power supply range * Small outline plastic package SO16 or PSOP2 16 [[文件:EM4095-125KHz-sch.png]] [[文件:EM4095-PCB.png]] http://www.emmicroelectronic.com/products/rf-identification-security/rf-reader-ics/em4095 * [http://www.advanide.com/wp-content/uploads/products/rfid_reader_ics/EM4095.pdf EM4095 Datasheet] * [http://www.emmicroelectronic.com/sites/default/files/public/products/datasheets/an404.pdf EM4095 APP Note] <br><br>
