Features:
The GC-IP1000 interpolation IC has been de­signed for connection to incremental position and

angular measurement systems with sine-shaped output signals with a 90° phase shift. It can be op­erated at a large number of transducer systems
working according to the most varied measuring principles. With a maximum interpolation rate of 1000 the IC is capable to slit the input signal pe­riod into up to 1000 segments. An internal counter

provides a counting value which can be output via a serial interface. Furthermore there is the possibility to output the data as a pair of square waves for processing externally.
The GC-IP1000 is ideal for single chip interpolation systems, micro-computer based measuring de­vices, as well as multi channel systems. Proprietary automatic gain and offset regulation, as well as the possibility of an analogue phase correction ensure a high measuring precision under industrial conditions. An integrated measuring value trigger enables the use in real-time applications.
