The MD011 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 embedded 12 channel GPS Receiver. In addition, an external 1pps input can override the internal receiver as the primary 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.
