Abstract: A router, for routing at least one input signal to at least one output, comprises at least one input module and at least one output module. Each of the input and output modules includes at least one clock selector circuit for selecting from among a first and second clock signal, and an oscillator signal, as a common output clock signal for the at least first router, based in part on whether at least one of the first and second clock signals has toggled. The clock selector circuit provides redundancy as well as distribution of clock signals among elements within each module.

Seventh, eighth and ninth discrete links couple the second routing engine to the second routing engines, respectively. Tenth and eleventh discrete links couple the second routing engine to the second routing engines, respectively. A twelfth discrete link couples the routing engine to the router engine.

Abstract: A linearly expandable router is comprised of first, second, third and fourth router components. First, second and third discrete links couple an input side of a routing engine of the first router component (102) to an input side of a routing engine of the second, third and fourth router components. Similarly, fourth and fifth discrete links couple the input side of the routing engine for the second router component to the input side of the routing engine of the third and fourth router components, respectively. Finally, a sixth discrete link couples the input side of the routing engine for the third router component to the input side of the router engine for the fourth router component.

Abstract: Supportably mounted by each chassis of a multi-chassis broadcast router are primary router matrix cards, redundant router matrix cards and clock-demanding input and output cards. A first master clock resides on the primary router matrix card of a first chassis while a second master clock resides on the redundant router matrix card of a second chassis. Each master clock is configured to provide a respective common clock signal to all of the input and output cards of the first and second chassis. Control logic determines whether the first master clock or the second master clock issues the common clock signal.
