TDU-310 Pulse/Data Distribution Amplifier for ICD-GPS-060 signals0 pages

TDU -310
Multi Channel Time Distribution Unit

Features:

Dual inputs with automatic switchover

10 individually buffered outputs of 3 signal outputs

Have Quick, BCD and 1PPS outputs compliant with ICD-GPS-060

The TDU-310 is a high output count, high
performance time signal distribution amplifier. It
is specifically designed to distribute the precise
time code signals generated by military GPS
receivers compliant with ICD-GPS-060
The TDU-310 provides 10 output channels of
each of three signals – 1PPS, Have Quick and
50 bit/sec BCD time code.
Two independent input references are
supported, with fault monitoring and switchover
to a backup reference if the primary source
fails. Manual override of source selection is
possible via a front panel mounted switch
The 1PPS output pulse width is set to 20
microseconds, independent of the input pulse
width.

The 1PPS outputs are individually selectable for
either a low or 50 ohm source impedance drive into
a 50 ohm load.
BCD time code outputs are available with either
RS232 (single ended) or RS422 (differential)
output buffers.
Optical isolation between the reference sources
and the TDU310 output buffers is optionally
available.
The TDU-310 is configured as a 1 U 19” rack
mount unit.
Power supply options include 115/230 VAC, 48, 24
or 12 VDC.
