GPS Disciplined Oscillators (GPSDO's)
Maintain accuracy and synchronization, even through GPS outages
GPSDO’s provide time and frequency reference signals that have the same long-term accuracy as the GPS signal itself, and also provide a “holdover” capability to maintain synchronization when GPS outages occur. Symmetricom offers a full line of these board-level products, which are an ideal choice when full instrument functionality isn’t required. For the many systems that require an embedded GPSDO, these proven modules reduce design cycle time and risk compared to developing a custom solution.
GPS-500
The GPS-500 is a 10 MHz OCXO-based GPSDO featuring a very small footprint, a low profile, and an extended operating temperature range, all in a design aimed at cost-sensitive LTE applications.

GPS-2000
Like the GPS-1000, the GPS-2000 is a 10 MHz OCXO-based GPSDO with a small footprint and firmware enhancements aimed at avionics applications. However, the GPS-2000 goes further, adding additional telemetry features and a daisy- chain redundancy capability for mission- critical applications. The GPS-2000 also has a built-in high-isolation distribution amplifier, enabling it to provide five 10 MHz outputs.

SSM-2000 and SSM-2650
Aimed at radar applications, the SSM-2000 and SSM-2650 both provide six 100 MHz outputs with high stability and very low phase noise. Both units are self- contained with integrated power supplies, filters, and a distribution amplifier. Both can be operated as free- running sources or disciplined by a 10 MHz or 1 PPS input. The SSM-2000 is based on a single-oven OCXO and operates from -25°C to +75°C. The SSM-2650 uses a double-oven OCXO and operates from -55°C to +80°C.
