Pentek Model 7190 Multifrequency Clock Synthesizer

Pentek announced the Model 7190 Multifrequency Clock Synthesizer. All eight output clocks are phase locked to an external frequency reference, typically 5 or 10 MHz. The 7190 uses four TI CDC7005 Clock synchronizers, each controlling a quad frequency voltage controlled crystal oscillator (VCXO). Each CDC7005 is programmed to select any one of its four VCXO frequencies, providing a total of sixteen different VCXO frequencies for the board. Each of these frequencies can then be divided by 1, 2, 4, 8 or 16, resulting in 80 different clock frequency choices. Up to five different frequencies from this set can be delivered to the eight front-panel SMC output connectors, or a single identical clock can be sent to all eight outputs. Numerous other combinations are also possible, depending upon the specific configuration of the A/D and D/A boards.
