Product Details


Fig. 1 Functional Block Diagram

The ASNT_PRBS20_1 is a broadband 27-1 PRBS generator intended for test, prototyping, microwave, and communication applications. The amplitude and phase can be individually adjusted on both differential outputs. Jitter can be inserted onto either differential output with a bandwidth up to 500kHz. The output amplitude on both PRBS outputs can be varied from 0V to 1V single-ended peak to peak. A single-ended clock from 10MHz to 18GHz with an amplitude as low as 50mV peak to peak may be applied to the clock input. A buffered differential clock output is provided on the board. A differential Sync Output divides an input clock from 1 to 256. The Sync Output is capable of displaying an eye diagram at divide-by-16 and a PRBS waveform output for 127 or 254. An on-board PRBS reset switch is present and should be used to preset the generator to avoid the all zero state lock-up.
