Theory of Operation
The AEDA-3300 translates rotary motion of a
shaft into three channels of digital output. The
AEDA-3300 series consists of the following key
parts: a single light emitting diode (LED) light
source, a focusing lens, a high-precision
codewheel, a photodetector IC with a set of
uniquely configured photodiodes, an interpolator
IC, and a line driver IC.
The LED emits light that is used to produce
modulated by the codewheel to produce a set
o f a n a l o g s i g n a l s . A h i g h p e r f o r m a n c e
compensation and interpolation IC processes
the analog signals to produce the digital A, B
and index signals. These digital signals are
further fed through a line driver IC that
produces the final differential outputs for
channels A, B, I, and their complements A, B
and I.
In a single size package, the AEDA-3300 is
available for wide selection of cycles per
revolution (CPR) options, from 600 to 20000.
This translates to a maximum resolution of
80000 counts after quadrature decode (4X),
satisfying the ever increasing requirement of
higher encoder counts for better motion feedback
performance.

Maximum Frequency and RPM
Notes:
1. Maximum allowable operating frequency will be lower due to limitation
in maximum permissible mechanical shaft speed.
The operable frequency is calculated based on
the formula:
Frequency (kHz) = CPR x (RPM / 60 x 10
As an example, for the 1000 CPR option, the
operable frequency is up to 200 kHz, i.e.:
Maximum operable frequency for 1000 CPR
option = 1000 x (12000 / 60 x 10
