ET2015

Overview
INTERPOLATION DEVICE (Interpolation factors of 1X or 5X) ET2015 FEATURES • Interpolation factor pin selectable (1X/5X) • Index gating pin selectable (90/180 electrical degrees of interpolated pulse) • Leading edge of gated index pulse occurs at 270 electrical degrees of analog input cycle, regardless of interpolation factor selected • Interfaces directly with ET2010 Analog Signal Processor and ET7272 Line Driver • Single supply operation • Handles Sine/Cosine inputs from DC to 125KHz • Sine/Cosine input voltage range 400mVpp to 4Vpp on 2.
5VDC reference • Outputs are NPN Collector with 4K pull-up; sink up to 4mA external load • Outputs TTL and CMOS compatible DESCRIPTION This ET2015 is a monolithic bipolar integrated circuit designed to facilitate increased resolution in optical encoder applications by converting the incoming sine and cosine signals to an interpolated quadrature digital output at 1 or 5 times the input frequency.
