Further information By evaluating the pseudo-random sequence (PZF), which is part of the DCF77 signal in addition to the amplitude modulation, the PZF clock is capable to reproduce a time pattern in the range of microseconds. This allows generation of high precision pulses and an accurate adjustment of the main oscillator of the system. Besides various standard frequencies, the board provides a programmable frequency output. Additional features of IMS-PZF clock are pulses per second (PPS) and per minute (PPM) and IRIG timecode outputs.
RoHS Yes
Status info Status info by 4 LED light indicators (2mm light pipes)
  • Init - blue: while the receiver passes through the initialization phase
  • Field - green: minimum field strength needed for the correlation reception is detected
  • Ant Fail - red: antenna faulty or not connected
  • Fail - red: time is not Synchronised
Frequency Outputs Accuracy depends on oscillator (standard: OCXO-SQ), see oscillator list
Pulse outputs Pulse per second (PPS) and pulse per minute (PPM). TTL level, pulse width: 200msec
Accuracy of Pulse Outputs Better than +/- 50μsec after Synchronisation and 20 minutes of operation.

WEEE status of the product This product is handled as a B2B category product. In order to secure a WEEE compliant waste disposal it has to be returned to the manufacturer. Any transportation expenses for returning this product (at its end of life) have to be incurred by the end user, whereas Meinberg will bear the costs for the waste disposal itself.
Type of Antenna DCF77 outdoor antenna AW02
Cable type Coaxial cable RG58 indoor or outdoor usage (BNC-, N-Norm-connector)
Synchronisation Time 2-3 minutes after correct DCF77 signal reception
Switch Outputs Four TTL outputs can configured independently for the following modes:
- free programmable cyclic or fixed impulses
- timecode
- timer mode; three 'ON'- and three 'OFF'-states can be setup per day
The switch states can be inverted for all three outputs, the impulse lengths are configurable.
The impulse output can be configured for all channels together to 'always' or 'ifsync'.
Antenna Connector BNC-connector
Backup Battery Type CR2032 - button cell lithium battery
When main power supply fails, hardware clock runs free on quartz basis, almanac data is stored in RAM
Life time of lithium battery min. 10 years
Current Consumption +5 V 1,1 A to 1,4 A (depends on oscillator option)
Receiver Quadrature receiver for optimized evaluation of the DCF signals (amplitude and phase modulation)
