DESCRIPTION
The GH65C11-X is designed to receive input
from standard quadrature optical encoders.
The power management feature allows power
to the encoder to be applied only during
sampling intervals, thus conserving power
SERIES 65
Optical Encoder Interface
FEATURES
• Interfaces with all Grayhill and
• Power Reduction of Up to 75-90%
• User Selectable Output Modes:

Temperature:
C = Commercial (0° C to 70° C)
N = Industrial (-40° C to 85° C)
* The SS package style is not available in the -40°C to 85°C temperature range.
• Simplified Microprocessor Interface
• Debounces Encoder Integral
• Ideal for Battery Powered
(especially advantageous in battery powered
systems). Sample rate is a nominal 4K per
second allowing high speed quadrature input.
The optical encoder interface can operate in 1
of 3 user-selectable output modes. These
Reduces Design Time

modes are: magnitude and direction, up and
down count, and standard quadrature.
Debouncing of an integral pushbutton switch
within the optical encoder can also be
accomplished.
