Valpey Fisher Introduces New Quad Output Frequency Translator.VFFT110 Series Expands Timing Modules Product Line HOPKINTON, Mass. -- Valpey Fisher Corporation (AMEX AMEX See: American Stock Exchange : VPF VPF vascular permeability factor; see vascular endothelial growth factor, under factor. ), a world leader in low noise timing solutions announced today the VFFT110 Series Quad Output Frequency Translator. This frequency translator accepts an input frequency up to 800MHz and provides an output frequency to 1.5GHz. The device operates over a -40[bar] C to +85[bar] C temperature range. Applications include OC-192 / OC-48 optical networks, SONET, SDH (Synchronous Digital Hierarchy) The European counterpart to SONET. See SONET. SDH - Synchronous Digital Hierarchy , ATM, and DSLAMs. "The VFFT110 Series allows the user to select 1 of 4 input and output frequencies up to 1.5 GHz, making the module ideally suited for frequency translation from one FEC See forward error correction. FEC - Forward Error Correction frequency to another," stated Walt Oliwa, VP, R&D, at Valpey Fisher. "With an input of 622.080 MHz and an output of 669.326 MHz, the output jitter over a bandwidth of 50 KHz to 80 MHz is less than 0.250 ps." The VFFT110 Series is a complete solution which includes an on board regulator for improved power supply rejection ratio In electronics, Power supply rejection ratio or PSRR is a term widely used in op-amp datasheets; used to describe the amount of noise from a power supply that the particular op-amp can reject.
