GPS Disciplined Oscillator Module
Former Model C6300
MD-010
M
The MD010 is a Vectron standard platform module that provides 1 pps TTL,10 MHz sine wave and 10 MHz square wave outputs that are
disciplined to an external 1pps reference. Internal to the module is a Vectron oscillator, ranging from a TCXO to a double oven OCXO, dependent
upon performance requirements. Internal oscillators are capable of achieving an aging rate less as high as than 0.1ppb/day and stability
over the operating temperature range of less than 0.2ppb. In addition to the 7 standard models included in this data sheet, due to Vectron’s
extensive portfolio of oscillators and a firmware driven architecture, Vectron can customize a solution for your specific application.
Features
• Embedded GPS Receiver
• 1pps TTL output signals standard
• 10MHz sinewave and square wave outputs standard
• Other output frequencies available
• Embedded oscillator dependent upon holdover requirements
• Serial communications interface standard
