A very compact 32-channel digital delay module has been designed to fit in a single VNM 6 U unit. It is equipped with both VME and Fast Intercrate Readout (FAIR) interfaces. Furthermore, a local manual programmability was implemented to use the modulealso in a stand-alone mode. A variety of NIM and ECL output have been implemented. A special ECL input allows the selection of different output regimes. The thermal stabilization is controlled via a PLL based circuit. The main features of the module are the wide range for the delay and the width of the output pulse: from 25 ns up to 6400 ns, in 25 ns steps; and the low jitter: values of the order of 27 ps (11 ppm) were measured in several bench tests.

Abstract

A very compact 32-channel digital delay module has been designed to fit in a single VNM 6 U unit. It is equipped with both VME and Fast Intercrate Readout (FAIR) interfaces. Furthermore, a local manual programmability was implemented to use the modulealso in a stand-alone mode. A variety of NIM and ECL output have been implemented. A special ECL input allows the selection of different output regimes. The thermal stabilization is controlled via a PLL based circuit. The main features of the module are the wide range for the delay and the width of the output pulse: from 25 ns up to 6400 ns, in 25 ns steps; and the low jitter: values of the order of 27 ps (11 ppm) were measured in several bench tests.
