LS7566 - 24-BIT FOUR-AXES QUADRATURE COUNTER

Description

The LS7566 consists of four identical modules of 24-bit programmable counters with direct interface to incremental encoders.

The modules can be configured to operate as quadratureclock counters or non-quadrature up/down counters.

Features

  • Read/write registers for count and I/O modes. Count modes include: Non-quadrature (Up/Down), Quadrature (x1, x2, x4), Free-run, Non-recycle, Modulo-n and Range limit.
  • Separate mode-control registers for each axis.
  • Interrupt output and interrupt mask register.
  • 40 MHz count frequency, 5V 20 MHz count frequency, 3V.
  • Sets of 24-bit counters, preset registers, comparators and output latches and 8-bit status registers for each axis.
  • Digital filt.
