Figure 1. Functional Block Diagram

The ASNT_PRBS43A can be used for test applications, design verification, and R&D environments. The 2^7-1 or 2^15-1  pseudo random bit sequence (PRBS) generator operates from 10kbps to 48Gbps. Either an external half-rate clock or a reference clock to the onboard PLL is needed to generate the data outputs. Some output clock and data channels have adjustable phase and amplitude. The Sync output provides an oscilloscope triggering signal to view the data pattern for PRBS7 or eye diagram of PRBS7/PRBS15. A Windows GUI (compatible with Windows XP, 7, 8) is used to control the amplitude, phase, PRBS reset, divide ratio for sync and clock input control through a USB-B connector on the ASNT_PRBS43A. Power is supplied with an included AC-DC power supply.
