RG-59
From Wikipedia, the free encyclopedia
RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms.
It can be used at baseband video frequencies or, for short distances, at broadcast frequencies. Its high-frequency losses are too great to allow its use over long distances at broadcast frequencies; in these applications, RG-6 is used instead.
RG-59 is frequently used to synchronize two digital audio devices, such as ADAT optical devices. This is called word clock.
