MD-011 GPS Disciplined Oscillator Module Former Model C6350 MD 1 -01 MD-011 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.

Temperature stabilities applyt o -20 to +70 ˚C modules. For other temperatures the temperature stability will vary, however the hold over values over defined temperature ranges remain constant. 3) 24 hour average when locked to GPS 4) The status locked indicator is intended to indicate when the module is fully locked to GPS. 5) The Hardware OK indicator is intended to indicate when the module is operating properly without any failures, including hardware, software or parameter out of range. See protocol for further information. 6) Open collector input bit. 7) If the minimum supply current is not exceeded, the Antenna Open Flag will be set. Over current will be set if maximum is exceeded. Circuit has overcurrent protection. 8) The Rx pin is the serial interface input and the Tx pin is the serial interface output. The serial interface shall operate at 9600 baud with eight (8) data bits, one (1) stop bit and no parity. 9) This holdover performance also applies to the temperature deviation over the entire operating range of -20 to +70˚C.
