FSK Modem for Industrial Control
參考設計 屬於: Analog Devices
DS8500 on the master side of HART communication. D_IN receives data from the microcontroller's UART. D_OUT transmits data to the UART. Active-low RST is the DS8500 reset. OCD is a carrier-detect signal that determines a FSK signal with a valid amplitude at the input of the demodulator
