Key Features
DCF77 Code Generator

Leap Second Capability
Daylight Saving Capability
Amplitude Modulation and Phase Modulation
TCXO Reference Frequency

Description
DCF77 Code Generator

GEN77 generates all signals that are needed to drive or to simulate a DCF77 compatible transmitter: 77.5 kHz reference for the carrier, time marks for the AM, PZF pulses and PZF window for the PM. All output signals are based on one 10MHz reference frequency. This reference frequency is either generated by the on board quartz oscillator (TCXO, optional: OCXO) or applied externally. The beginning of a second can be synchronized with an external signal.

Characteristics
DCF77 Code Generator

Display:	LC-display, 4 x 16 characters
Control elements:	Shows time/date and other information of the system. Also several user parameters can be controlled and changed with 4 keys. Parameter Setting: Changeover of daylight saving is generated automatically. Beginning and ending of daylight saving may either be defined by exact dates for a single year or using an algorithm which allows the generator to recompute the effective dates year by year. The date of insertion of a leap second can be edited, too. GEN77 generates the announcement of the leap second as well as the leap second itself. The length of the time marks 0 to 15 can be controlled by 16 TTL inputs.
