Rj / Sj Injector



Supporting multiple data rate up to 12.5Gbps, RJI12G works with any NRZ differential signal. 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. Moreover, the multiple stress test items are integrated such as, Output Swing Level in the range of 200mVpp to 2Vpp differential, Intra-pair Skew control up to +/- 120ps, Adjustable Duty Cycle Distortion for +/- 8ps.
