The ZEN2014F is a 24 bit programmable universal counter LSI. The ZEN2014F counts phase-shifted signals and up/down pulse signals that are generated from rotary encoders or linear scales. The counter response speed is up to 33MHz(max). 24bit binary up/down counter. Counter response speed: 33Mcps.(max)(CLK fo=33MHz at 50% duty). Input frequency of count pulse : *Phase-shifted signal input: A/B phase input DC--8.25MHz(less than fo * 1/4). *Up/down pulse signal input: Up/down input DC--16.5MHz(less than fo * 1/2). Edge evaluation selection : single/double/quad. Count value coincidence detection. Software compatible with The ZEN2011P. QFP44pin. 5V power supply. Low price.
