Traditional time and frequency distribution is defined by splitting and amplifying a signal to as many devices as needed. The distribution amplifier became a mainstay in precision time and frequency systems. Today there is greater access to precision timing considering more clocks in space transmitting global navigation signals and more network connectivity able to maintain higher levels of timing accuracy. A new generation of master clocks is capable of leveraging these trends while offering flexibility to generate the signal types and quantities wherever needed. Distribution amplifiers can still be an important “brick” in the system to meet needs for redundancy, reliability and cost-efficiency. This white paper describes the issue of providing precise time and frequency signals of the type and quantity needed by the application using commercial-off-the-shelf devices from Spectracom.
