Quadrature Decoder/ Counter Interface ICs
Description
The HCTL-20XX-XX is CMOS ICs that perform the quadrature decoder, counter, and bus interface function. The HCTL-20XX-XX is designed to improve system performance in digital closed loop motion control systems and digital data input systems. It does this by shifting time intensive quadrature decoder functions to a cost effective hardware solution.
The HCTL-20XX-XX consists of a quadrature decoder logic, a binary up/down state counter, and an 8-bit bus interface. The use of Schmitt-triggered CMOS inputs and input noise filters allows reliable operation in noisy environments. The HCTL-20XX-XX contains 32-bit counter and provides LSTLL compatible tri-state output buffers. Operation is specified for a temperature range from -40 to +100°C at clock frequencies up to 33MHz.
The HCTL-2032 and HCTL-2032-SC have dual-axis capability and index channel support. Both devices can be programmed as 4x/2x/1x count mode. The HCTL-2032 and HCTL2032-SC also provides quadrature decoder output signals and cascade signals for use with many standard computer ICs
The HCTL-2022 has most of the HCTL-2032 features, but it can only supports single axis and fixed at 4x count mode. The HCTL-2022 doesn’t provide decoder output and cascade signals.
