3 channel interpolator IPE40

programmablewith ABZ interfacewith SPI interface

The interpolation unit (IPE40) is used to increase the resolution of incremental distance and angle measuring systems with sinusoidal output signals that are phase-shifted by 90 °. It is suitable for sensors with a standardized voltage or current interface. An adjustable minimum edge distance at the output as well as the programmable analog and digital hysteresis enable use even with impaired input signals. - Input signals - Sine / cosine / reference signal Differential / single-ended Adjustable gain for 1Vpp / 660mVpp / 530mVpp / 80mVpp Maximum 1.2MHz for interpolation rates ≤ 20 Maximum 750kHz for interpolation rate = 32 Maximum 600kHz for interpolation rate = 40 - Interpolation rate 40 / 32 / 20 / 16 / 8 / 4 Edges per sine period - Zero signal processing - Adjustable width of the reference signal at the output - Interference suppression - Adjustable hysteresis analog Adjustable hysteresis digital Adjustable minimum edge separation at the output
