How: DCF receiver module with DCF antenna time-tuned DCF77 signal relay (Frankfurt 77.5 kHz). The antenna inductive signal is sent to the IC for amplification, demodulation, and then identified by the MCU so that the timing center date and time are completely consistent. Below you will find important configuration and circuit diagrams. Technical data Product number: DCF-1060N-800 RCCM category: DCF/77.5KHz single frequency module PCBA size: 21.5x13.5x1.0mm/FR4 Antenna size: AR10x60mm/High Q Nominal frequency: 77.5KHz 300Hz Sensitivity: 26 2dB Receiving IC: SP6007 Working Voltage: 1.1...3.3 V Current consumption: 85 mu;a max Reception frequency: 77.5 KHz Board size (without antenna) LxWxH: 22x13.5x1mm Antenna quality: Lx Oslash;: 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 the on/off switch and must be set to logic low. Note: Single frequency modules cannot be switched between different DCF/WVB/HBG/BPC frequencies, JJY dual frequency modules can be switched between 40K/60K two frequencies to form a certain single frequency module, only can receive signals in this frequency band. Package includes: 1 * Receiver Module
