Description

The NAMC-PTM is a redundant, high-accuracy holdover clocking source.  It features a Voltage Controlled Oven Compensated Crystal Oscillator (VCOCXO) as well as a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO), several sensors for controlling/compensating tasks, and various customization options.

Main purpose of the NAMC-PTM is the detection of clocks or pulses from an external (GPS) or chassis-internal source (NAT-MCH), rating of the quality of these signals, and offering a high-accurate clock source to the µTCA-System and/or towards the front plate.

The clock system is capable to lock to various incoming references, generate a wide range of possible output clocks and provides and extremely accurate holdover functionality based on the compensated local oscillator.

Various sensor data is used to compensate frequency variations of the local oscillator caused by mechanical vibration, temperature, and supply voltage changes.

The NAMC-PTM can be operated in a standard AMC-slot in nearly any MTCA-chassis. If the customer’s demands require the full payload board capacity of an MTCA-system, the NAMC-PTM can be operated in designated PTM-slots of a specialized and modified MTCA-chassis.
