In-Line Rj & Sj Jitter Injector - RJI12G series

Random & Sinusoidal Jitter Injector - RJI12G series

Supporting multiple data rate up to 12.5Gbps, RJI12G works with any NRZ differential signal including PCI Express, SATA, SAS, Fiber Channel and USB 3. The unique architecture, “Jitter injection onto receiving data stream” enables RX Loop-back test configuration up to 440ps jitter. Internal Random Jitter engine generates Gaussian-fit curve, ranged up to 1GHz with two selectable bandwidth ([10k-1.5MHz] and [1.5M- 100MHz or 1.5M-1GHz]) up to 10ps(rms) at 0.1ps resolution. Two individual Sinusoidal Jitter is fully programmable up to 440ps at 1ps resolution for 10k - 400MHz at 1KHZ resolution. The built-in External jitter mixer allows user-defined jitter input, available as 1ps at 1mV up to 500MHz. Multiple stress test items are integrated such as, Adjustable Duty Cycle Distortion for +/- 8ps, Output Swing Level in the range of 200mVpp to 2.5Vpp differential, Controllable 2 taps - De-emphasis up to 6.0dB, Intra-pair Skew control up to +/- 120ps.
