1.0 Introduction

This document describes the Phenix Programmable Pulse Generator (PPG). It is contained on one 9U x 400mm eurocard and one 9u x 120 mm transition module. The main function of the system is to provide 8 programmable Pulses that are available in TTL, NIM AND ECL logic levels and produce the Following signals .

Level 1 Accept (TTL,NIM,ECL)
Programmable Pulse (TTL,NIM,ECL)
Pulse Description (LVDS)
Transition module allow daughter cards to produce any type of output

2.0 Board Level Overview

The PPG contains a 256 byte pattern memory which can be programed via the VME64 Backplane and addressed by the mode bits (from the granule timing module (GTM)) to produce any desired pulse pattern. The pulse width is selectable through on board registers from 26.5 ns up to 106 ns in 26.5 ns steps. The Pulse can also be delayed up to 26.5 ns in .15 ns steps . Another 256x8 memory is used to describe what pulse combination occurred and is brought to the front panel as LVDS. All signals are brought to the front panel of the PPG as TTL,ECL and NIM. Level 1 synchronized to the 9.38MHZ clock is also brought to the front panel as TTL,ECL and NIM. The PPG can function independent of the GTM, by use of its built in scheduler. The on board scheduler is 256 bytes deep and it allows any number of patterns and repeats. The PPG can also be programed as a continuos pulse generator (heart beat generator) triggered by the GTM mode bits or software. The frequency of the heart beat ranges from .56 HZ -4.7MHZ with a pulse width of 106ns - 27 us. once started the heart beat can only be turned off by a board reset ( independent of GTM start and stop pulse).
