EM4095 - Read / Write Analog Front-End

General Description

The EM4095 (previously named P4095) chip is a CMOS integrated transceiver circuit intended for 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 modulat

Key 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.
  • Direct antenna driving using bridge drivers.
  • Data transmission by OOK (100% Amplitude Modulation) using bridge driver Typical Operating Configuration Read Only Mode LA +5V CRES CDV1 +5V CDV2 RDY /CLK 1 16 CDC2 2 15 CFCAP 3 14 SHD DEMOD_OUT 4 EPM44009955 13 5 12 MOD P 6 11 CAGND 7 10.
