ET2015 - INTERPOLATION DEVICE
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.
Please refer to the Timing Diagram.
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
* Inte
