This connector is a standard-polarity, standard-gender 50-ohm MMCX jack, also known as a MMCX female connector. The mating cable should have a 50 ohm MMCX plug (male connector).16 The MMCX jack is used to feed a reference clock signal from external equipment, such as test equipment with a 10MHz reference output.

The MMCX reference input can be selected with the appropriate [wiki:../Configuration#ReferenceClockSource DIP switch setting].
