ET2024 Datasheet (ETIC) - INTERPOLATION DEVICE

ET2024, INTERPOLATION DEVICE

This ET2024 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 2 or 4 times the input frequency.

Please refer to the Timing Diagram.

ET2024 Features

* Interpolation factor pin selectable (2X/4X)

* 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
