FUNCTIONAL DESCRIPTION The 3D3622 device is a versatile 22-bit programmable monolithic pulse generator. A rising-edge on the trigger input (TRIG) initiates the pulse, which is presented on the output pins (OUT,OUTB). The pulse width, programmed via the serial interface, can be varied over 4,194,303 equal steps according to the formula: tPW = tinh + addr * tinc www.DataSheet4U.com PIN DESCRIPTIONS TRIG RES OUT OUTB AE SC SI SO VDD GND NC Trigger Input Reset Input Pulse Output Complementary Pulse Output Address Enable Input Serial Clock Input Serial Data Input Serial Data Output +3.3 Volts Ground No Internal Connection where addr is the programmed address, tinc is the pulse width increment (equal to the device dash number), and tinh is the inherent (address zero) pulse width. The device also offers a reset input (RES), which can be us...
