GPS500

Overview

GPS Time Code Generator

The GPS500 from Masterclock is a precision IRIG-B or SMPTE time code generator. It provides a source of very stable time code, referencing time and date information from atomic clocks in the GPS satellite constellation.

It extracts timing reference from these signals and generates time code that is synchronized within less than 10 microseconds of UTC (Universal Coordinated Time).

Technical

Generates SMPTE, EBU or IRIG-B Time Codes
Synchronized to atomic clocks in GPS satellites
Provides legally traceable time to UTC
-11.5 to +12 hour time zone offsets in 30-minute increments
Automatic Daylight Saving Time
NMEA/Kinemetrics/Truetime serial protocol output
Wide DC power supply input range: 12 to 48 VDC
Switch selectable Time Zone and DST
Switch selectable format and baud rate

Specifications

Time Reference

Accuracy: SMPTE output accuracy of ± 20 microseconds, when synchronized
Accuracy: IRIG-B0 (DCLS/PWM) output accuracy of ± 90 microseconds, when synchronized
Accuracy: IRIG-B1 (AM) output accuracy of ± 1.4 milliseconds, when synchronized
Accuracy: PPS output accuracy of ± 60 nanoseconds, when synchronized
Should the GPS500 lose GPS signal it will revert to an internal TCXO oscillator and maintain an accuracy of ± 1 minute per year. The PPS output is synchronized to the internal TCXO oscillator.

Outputs

SMPTE, EBU:30, 25 or 24fps
IRIG-B: 1 kHz modulated, level - 5 Vpp
IRIG-B: unmodulated, single ended 5 V
PPS: 5 V-TTL, accuracy ± 60 nanoseconds (when synchronized to GPS)
PPS: Pulse width configurable via switch from ~200 ms to ~1 ms
Serial output via RS-232/RS-485 NMEA Kinemetrics/Truetime protocol
Date encoded references (IRIG 1344 and SMPTE Leitch date format or 309M)
