Precision Timing

Affordable Precision Timing for Your Systems

Many of today’s data acquisition systems, high-speed cameras, and remote sensing devices benefit from the addition of precision timing for correlating the outputs of systems that may be operating in different geographic locations. Existing time-code generation devices are large, power-hungry, and expensive. SLS engineers have developed the JT-DO1 GPS-Disciplined IRIG-B Timecode Generator to provide a compact, affordable timing solution that delivers precision timing to your systems.

SLS JT-D01 Timecode Generator


Precision Timing

Provide external devices with IRIG-B DCLS and 1 PPS signals having nominal timing accuracy better than 20 ns to UTC.


Unlike bulky time servers, JT-DO1 fit in the palm of a hand, allowing seamless integration into existing or new installations.

Low Power

High-performance in a small package, powered from a low-wattage DC source or even a small battery for portable applications.


Availability in a standalone ruggedized case, or as an OEM PCB solution to integrate inside your existing hardware.

The SLS JT-DO1 Timecode Generator provides the user with an IRIG-B007, DC level-shift output in addition to a precision GPS 1 pulse-per-second (PPS) output. JT-DO1 delivers timing accuracy better than 20 ns to UTC. Basic technical specifications of the JT-DO1 are given below. 


Dimensions 4.62-in x 2.12-in x 1.0-in (L x W x H)
Mounting 0.2-in holes (4x)
Supply Voltage 9.5 V - 13.5 V
Current Consumption 60 - 160 mA
Operating Temperature 0°C - 60°C
Timing Accuracy (Clear Sky) ≤ 20ns
Timing Accuracy (Indoors) ≤ 500ns
Serial 115,200 N-8-1

The standard JT-DO1 timecode generator includes an integrated patch antenna. For indoor applications or other applications where the device does not have a clear-sky field of view, the JT-DO1 is available with an additional coaxial input to support the connection of an external GPS antenna.

JT-DO1-12 Configuration Options

SLS presently offers the JT-DO1 Timecode Generator in three configurations:

  1. Custom Circuit Board –  Includes only the custom circuit board with integrated antenna and no external housing
  2. With Non-Environmental Housing – Pictured, includes the custom circuit board in a non-environmental, rugged plastic housing with integrated antenna
  3. With Environmental Housing – Includes the custom circuit board in a sealed 6061 aluminum environmental housing with connection for an external antenna

SLS offers an additional optional configuration for those customers demanding long-duration timing holdover stability when GPS synchronization is lost. Contact SLS today to discuss your timing requirements and to obtain more information on our innovative timing solutions.
