High accuracy DCF77 correlation receiver for generation of standard frequencies and pulses

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.
