Model 5390 Multifrequency Clock Synthesizer - 3U VPX General Information five different submultiple clocks, a wide Model 5390 generates up to eight synthe- range of clock configurations is possible. In systems where more than five different clock sized clock signals suitable for driving A/D and D/A converters in high-performance outputs are required simultaneously, multiple 5390’s can be used and phase-locked with a real-time data acquisition and software radio 5 to 100 MHz system reference. systems. The clocks offer exceptionally low phase noise and jitter to preserve the signal PCI Express Switch quality of the data converters. These clocks are Model 5390 includes a PCIe Gen. 2 switch. synthesized from on-board quad VCXOs (voltage controlled oscillators) and can be The switch provides a total of 24 PCIe lanes to the Fabric-Transparent Crossbar Switch phase-locked to an external reference signal. on 6 ports.
