KL-3400 Real Time Clock

The KL-3400 Real Time Clock combines up to seven high precision timing inputs to an 1PPS or 10MHz output signal more stable than any of the input signals.

Description

The KL-3400 is the most accurate RTC on the market – In contrast to such ‘paper clock’ approach, we have investigated the hardware requirements and actually built what we call a ‘real time clock’, i.e. a device, which accepts the output signals of various stable clocks and optionally a 1PPS timing signal (plus possibly some bulletin information and strategic operator decisions), and from these generates an optimized output clock signal under the control of software clock algorithms.
