描述 Description

The AD9501 is a digitally programmable delay generator thatprovides programmed time delays of an input pulse. Operatingfrom a single 5 V supply, the AD9501 is TTL- or CMOS compatibleand capable of providing accurate timing adjustmentswith resolutions as low as 10 ps. Its accuracy andprogrammability make it ideal for use in data deskewing andpulse delay applications, as well as clock timing adjustments.

Full-scale delay range is set by the combination of an externalresistor and capacitor and can range from 2.5 ns to 10 ms for asingle AD9501. An 8-bit digital word selects a time delay withinthe full-scale range. When triggered by the rising edge of an inputpulse, the output of the AD9501 will be delayed by an amountequal to the selected time delay (tD) plus an inherent propagationdelay (tPD).

The AD9501 is available for a commercial temperature rangeof 0°C to 70°C in a 20-lead plastic DIP and a 20-lead plasticleaded chip carrier (PLCC).
