Overview
The AD9500BP, produced by Analog Devices Inc., is a digitally programmable delay generator. This component is designed to provide highly accurate and programmable delays, making it suitable for various precision timing applications. The AD9500BP features an 8-bit digital control interface, allowing for fine-tuned delay settings with a resolution as small as 10 ps. It supports both single-ended and differential ECL input signals and includes separate trigger and reset inputs. The device is available in several package types, including 24-lead cerdip, 28-lead PLCC, and leadless surface mount packages, and it operates over a wide temperature range, including industrial and extended temperature grades.
