The CT1DMK Reflock II is a universal synthesizer that can lock an oscillator at virtually any frequency up to 250MHz (1.1 GHz with a prescaler option) to a frequency standard (commonly 10 MHz) or to a 1 PPS signal from a GPS receiver. It is primarily designed for hams to use as a way to stabilize the local oscillator of a microwave transverter, but there are obviously lots of other interesting possibilities.
The design incorporates the latest CPLD from Altera. The size of CPLD used in the Reflock-II allows for an enhanced resolution 1 PPS circuit plus capability of connecting to a microcontroller and things like lock detection and full numeric loop performance monitoring being possible.
A quality printed circuit board only, no parts included.
