Goodhd DCF77 Receiver Module Radio Time Module Radio Clock Radio Module Antenna

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 can be completely consistent. Below you will find important setup and circuit diagrams. Technical Specifications DCF---77.5KHZ single frequency specification: Product number: DCF-1060N-03A RCCM category: DCF/77.5KHz single frequency module PCB size: 25.0x11.5x1.0mm/FR4 Antenna size: AR10x60mm/High Q Nominal frequency: 77.5KHz±300Hz Sensitivity: 27±2dB Receiving IC: CME6005 JJY-40/60KHZ dual frequency specification Product number: JJY-1060N-MAS RCCM category: JJY/40+60KHz dual frequency module PCB size: 22.0x13.5x1.0mm/FR4 Antenna size: AR10x60mm/High Q Nominal frequency: 40/60KHz±300Hz Sensitivity: 40/60K:30/28±2dB Receiving IC: MAS6181B • Operating voltage: 1.1...3.3 V • Current consumption: 85 µA max • Receiving frequency: 77.5 KHz • 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 G ⇒ Operating Voltage = Pin V ⇒ data = pin T ⇒ Power On/Off = Pin P1 ⇒ 40/60K frequency selection = SEL ⇒AGC(Note 4: Optional Control for AGC On/Hold AON control pin has internal pull up which turns AGC circuit on all the time if AON pin is left unconnected. Optionally AON control can be used to hold and release AGC circuit. Stepper motor drive of analog clock or watch can produce disturbing amount of noise which can shift the input gain to non optimal level. This can be avoided by controlling AGC hold (AON=VSS) during stepper motor drive periods and releasing AGC (AON=VDD) when motors are not driven. The AGC should be in hold only during disturbances and kept on other time released since due to leakage the AGC can still change slowly when in hold.) • Important note: ⇒ PIN P1 is an on/off switch and must be set to logic low. Note: Single-frequency modules cannot be switched between different frequencies of DCF/WVB/HBG/BPC JJY dual-frequency modules can be switched between 40K/60K two frequencies to make a certain single-frequency module only can receive signals in this frequency band.
