describe:
DCF receiver module with DCF antenna tuned to time signal transmitter DCF77 ( for 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: 77.5KHz±300Hz
Sensitivity: 28±2dB
Receiving IC: SP6007 • Operating voltage: 1.1...3.3 V
• Current consumption: 85 µA max
• Receiving frequency: 77.5KHz
• Board size (without antenna) LxWxH: 22x13.5x1 mm
• Antenna quality: LxØ: 60x10mm
• Scope of delivery: 1 piece ⇒ DCF receiver module with antenna • connect: ⇒ Ground = Pin ⇒ Operating Voltage = Pin ⇒ 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. for 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.
