DCF77 Radio Time Receiver Module DCF-3850N-800 775KHz Radio Time Module Radio Clock Radio Module Antenna Electronic Components describe: DCF receiver module with DCF antenna tuned to time signal transmitter DCF77 (Frankfurt 77.5 kHz). The antenna induction signal is sent to the IC for amplification, demodulation, and then identified by the MCU, so that the date and time of the timing center are completely consistent. Below you will find important setup and circuit diagrams. Technical Specifications Product number: DCF-3850N-800 RCCM category: DCF/77.5KHz single frequency module PCBA size: 21.5x13.5x1.0mm/FR4 Antenna size: AP3x8x50mm/High Q Nominal frequency: 77.5KHz300Hz Sensitivity: 282dB Receiving IC: SP6007 Operating voltage: 1.1...3.3 V Current consumption: 85 A max Receiving frequency: 77.5KHz Board size (without antenna) LxWxH: 22x13.5x1 mm Antenna quality: Lx: 60x10mm Scope of delivery: 1 piece DCF receiver module with antenna connect: Ground = Pin G Operating Voltage = Pin V data = pin T Power On/Off = Pin P1 Important note: PIN P1 is an on/off switch and must be set to logic low. Note: The single frequency module cannot switch between different frequencies of DCF/WVB/HBG/BPC. JJY dual frequency module can switch between 40K/60K two frequencies. As a single-frequency module, it can only receive signals in this frequency band.
