Abstract

A timing architecture for integrating broadband, wideband, and narrowband subsystems (14-18) employs a broadland time base (100) having a first frequency, a wideband time base (102) having a second frequency, and a narrowband time base (104) having a third frequency.
The broadband, wideband and narrowband time bases (100-104) are independent from one another when the intergrated subsystems (14-18) are not co-located. Frequency justification is provided at the interfaces between the broadband and wideband time bases (100, 102), and between the wideband and narrowband time bases (102, 104). Phase alignment circuitry and methods are used to adjust the phases of signals wherever signal multiplexing and redundant equipment switching are provided within the time bases (100-104).
