Pentek introduced the Model 7191 programmable multifrequency clock synthesizer. The Pentek Model 7191 clock synthesizer uses low-noise VCXOs for the fundamental frequency generation. The VCXO output is followed by a clock synchronizer from Texas Instruments to enable synchronization with common frequency reference sources. The user-configurable PMC module is ideal for designers working with A/Ds and D/As. The price of the Model 7191 Multifrequency Programmable Clock Synthesizer is $2,995 USD.
