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.
