The UDC-IC 10 MHz Clock Converter is intended to accept a standard 10 MHz sinusoidal reference signal, convert it to a typical 5V TTL-level output, and distribute this output to 4 separate devices over individual coax cables.

Each cable driver element is designed to launch a signal through a 50-ohm series termination. With a single high-impedance load at the end of the 50-ohm cable, the load will see the incident signal as a square wave. Reflections back to the source are absorbed for the most part by the series termination in combination with the low-impedance driver.

If the 10Mhz Input Sine Wave is within tolerance, the front panel CLK and DCD LED Indicators will be green. If the 10Mhz Input signal is out of tolerance the CLK and DCD LED indicators will not be illuminated.

The 10MHz receiver card is also equipped with a low signal level detector circuit that cuts off the converter to prevent compromised clock signals from reaching downstream equipment. This will normally happen when the input signal falls below the minimum +5 dBm level. The front panel indicator, DCD will be on when an input signal of sufficient level is seen, and off when the cut-off circuit senses a low level or absent input.

The UDC-IC 10Mhz Clock Converter is simple to use by connecting a 50-ohm Coax Cable to the 10Mhz Sine Wave INPUT marked PORT B located on the rear panel. Then connect from one to four 50-ohm Coax Cables to the OUTPUT ports 1-4 located in PORT A.

The front panel LED marked PWR, CLK and DCD should be illuminated. If the CLK and the DCD LED’s are not illuminated, the UDC-IC 10Mhz Clock Converter is not receiving a good 10Mhz Sine wave.

The UDC-IC has a three year warranty and a 24 hour turnaround on warranty repairs
