TCO100 Time Code Generator


The TCO100 is a stabilized oscillator that generates IRIG-B, SMPTE or EBU TIME CODES. Although the TCO100 is designed to work primarily as a companion to the GPS500 master clock generator/receiver, it will function as a high-quality stand-alone source of accurate time code. When combined with a GPS500, the TCO100 will deliver precise time and date information virtually anywhere in the world. When operating as a stand-alone oscillator/time-code generator, the internal clock can be set with front panel switches or via RS232 control and will maintain stable time and frequency for long periods of time without further intervention or calibration.




  • Generates SMPTE, EBU, 30, 25 and 24 fps or IRIG-B (modulated and unmodulated) time codes
  • Functions as a backup time code source for master clock systems
  • Can be connected to a GPS500 master clock generator to automatically synchronize to GPS atomic clock time
  • Automatic Daylight Savings Time adjustment for North America and available for other countries
  • Temperature Compensated Crystal Oscillator (TCXO) provides accuracy of ±1 minute/year (<165 ms / day)
  • 6-digit red LED time or date display
  • All functions can be controlled via RS-232
  • -11.5 to +12 hour selectable Time Zone offsets in 30 minute increments



Time Code Output
SMPTE - 24, 25 or 30 fps NDF (Non Drop-Frame) 
IRIG-B(1) 1kHz, amplitude modulated
IRIG-B pulse-width coded 
Timing Characteristics
Reference: UTC/GMT (default) 
Date (SMPTE): Included in user bits per Leitch specification 
Date (IRIG-B): Included in Control Functions (CF) per IEEE 1344 specification 
Short term accuracy: < 10 µs (when locked to GPS) 
Long term stability: same as GPS atomic clock in GPS satellites (when locked to GPS) 
Drift (TXCO): +/- 1 min/year (standalone operation) 
PPS Output
PPS is synchronized to the 1Hz on-time reference marker of the time code generator and is accurate to within < 10us of the aforementioned event. It is approximately 100ms wide and positive-going. Output circuit is a TTL open collector with internal pull-up resistor.
