a 5 volt supply. Line drivers are low output impedance
devices, designed to drive signals over longer distances,
and are normally used with a matched receiver.
5.3.2 Analog signal output incremental encoders
Encoders that provide analog output are typically required
by high-end motors such as the high resolution servo
motors. Analog signal output encoders have the ability
to achieve higher resolution through external
interpolation electronics.
5.3.3 SSI signal output absolute encoders
Avago’s absolute encoders are designed with a
non-proprietary SSI standard output. This standard
communication protocol enables the encoder to be
interfaced, directly or through simple interface boards,
with most signal processing circuitries to provide
design-in exibility and easy integration into existing
motor controllers.
5.4 Encoders for BLDC Motor System: By Shaft Size
Motor shaft sizes dier from one application to another.
Shaft sizes of motors typically are linearly proportional
to the motor frame size or diameter. The shaft size
requirement of an encoder or its codewheel is typically

Note:
1. CPR to LPI Conversion. CPR range is typical value for a 1-inch outer diameter (OD) codewheel.
2. Shaft size. Typically 2 – 8mm for 1-inch OD codewheel. Larger shaft sizes possible if used with a larger OD codewheel.
3. Maximum RPM value is based on response frequency limitation of the encoder signal. Mechanical limit may be higher.
4. Motor Diameter is suggested minimum OD of a motor that the encoder series can t into.
