The ASNT_PRBS34A is a broadband 29-1 or 210-1 PRBS generator intended for test, prototyping, microwave, and communication applications. A single-ended or differential clock from 1GHz to 16GHz can be used to drive the generator. A dual 1/256 divider block with differential Sync Output divides the input clock allowing a PRBS9 and PRBS10 pattern view on an oscilloscope by using a divide ratio 511 or 1023. The PRBS9/PRBS10 data output is multiplexed to double the data rate, giving a maximum data rate of 32Gbps. An on-board DAC module, software controlled via USB interface allows to phase adjust the multiplexer clock input for all input clock frequencies in a specified range to ensure the best output is achieved. The built-in PRBS generator reset switch presets PRBS generator to avoid the all zero-state lock-up.
