AD9501
过期Digitally Programmable Delay Generator
概述
The AD9501 is a digitally programmable delay generator that provides programmed time delays of an input pulse. Operating from a single 5 V supply, the AD9501 is TTL- or CMOS compatible and capable of providing accurate timing adjustments with resolutions as low as 10 ps. Its accuracy and programmability make it ideal for use in data deskewing and pulse delay applications, as well as clock timing adjustments.
Full-scale delay range is set by the combination of an external resistor and capacitor and can range from 2.5 ns to 10 ms for a single AD9501. An 8-bit digital word selects a time delay within the full-scale range. When triggered by the rising edge of an input pulse, the output of the AD9501 will be delayed by an amount equal to the selected time delay (tD) plus an inherent propagation delay (tPD).
The AD9501 is available for a commercial temperature range of 0°C to 70°C in a 20-lead plastic DIP and a 20-lead plastic leaded chip carrier (PLCC).
