LS7566 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. In both quadrature and non-quadrature modes, the modules can be further configured into free-running, non-recycle, modulo-n and range-limit count modes.
LS7566 Key Features
- Read/write registers for count and I/O modes. Count modes include: Non-quadrature (Up/Down), Quadrature (x1, x2, x4), Fr
- 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, parators and output latches and 8-bit status registers for each axis
- Digital filtering of the input quadrature clocks for noise immunity
- 3-state Octal I/O bus
- 3V to 5.5V operating voltage range
