SD-15900
TWO-SPEED S/D OR R/D COMBINER
CONVERTER
DESCRIPTION
The two-speed combiner is designed
to work in conjunction with any two
synchro-to-digital (S/D) or resolver-to-
digital (R/D) converters such as
DDC’s two-channel SD-14620 Series
or two RDC-19220 Series.
These
combinations provide a complete
solution to implement two-speed S/D
or R/D conversion.
The SD-14620 Series is a small, low-
cost two-channel hybrid S/D or R/D
converter based on a single chip
monolithic. It features a velocity out-
put, which can be used to replace a
tachometer, and Built-In-Test (BIT).
The RDC-19220 Series is a single-
channel monolithic S/D or R/D con-
verter. It also features a velocity out-
put, which can be used to replace a
tachometer, and Built-In-Test (BIT).
The SD-15900 is a digital device
which combines the S/D or R/D digital
information from a coarse channel
and a fine channel to provide up to 22
bits of angular data.
The SD-15900 is set at the factory to
accept a 1 x 36 speed combination.
The combiner, as well as DDC’s
SD-14620 Series and RDC-19220
Series converters, can be powered
from the same +5 V DC power supply.
Please note that if you are using the
RDC-19220 Series, velocity scaling
components are necessary for the
device to function.
APPLICATIONS
The small-size components and the
high accuracy obtainable in two-speed
combinations make the SD-15900
ideal for use in modern, high-perfor-
mance military and industrial position
control systems. Typical applications
include radar antenna positioning,
navigation and fire control systems,
motor control and robotics.
