ULN-1100 User Manual
1Introduction
1.1 Overview
The ULN-1100 GPSDO includes an extremely high-performance GPS receiver that can acquire and
track up to 50 GPS signals down to a state of the art –160dBm, a 32bit processor that runs a Real
Time OS, four 100MHz LVDS outputs, one 100MHz CMOS output, two 100MHz Sine Wave
outputs, one 10MHz sine wave output, 1PPS UTC synchronized LVDS and RS-232 outputs, RS-232
control interface, and precision voltage references and DACs.
1.2 General Safety Precautions
The following general safety precautions must be observed during all phases of operation of this
instrument. Failure to comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards of design manufacture, and intended use of the instrument. Jackson
Labs Technologies, Inc. assumes no liability for the customer’s failure to comply with these
requirements.
1.2.1 Grounding
To avoid damaging the sensitive electronic components in the ULN-1100 GSPDO always make sure
to discharge any built-up electrostatic charge to a good ground source, such as power supply ground.
This should be done before handling the circuit board or anything connected to it, i.e. the GPS
antenna.
1.2.2 Power Connections
Make sure to connect the DC power to the device following the polarity indicated in Section 2.1 . Do
not reverse the power pins as this will cause serious damage to the circuit board.
1.2.3 Environmental Conditions
This instrument is intended for indoor use. It is designed to operate at a maximum relative
non-condensing humidity of 95% and at altitudes of up to 50,000 meters. Refer to the specifications
tables for the ac mains voltage requirements and ambient operating temperature range.
