IMS-LNO: 10 MHz sine low phase noise output module


This product is only compatible with Meinberg's line of modular IMS LANTIME systems.
Visit the IMS Information Page to learn more.
The IMS-LNO180 is a 10 MHz generator card and provides sinewave signals with low phase noise at four outputs. It has a microprocessor system which monitors the output signals and generates status signals for the management system. It may be preferably used in our modular IMS Systems, M900 timeserver platform and GPS based 3U housing.

Product Description

Functionnality
A high-quality oscillator is synchronized by the 10 MHz signal of the external reference clock and thus provides the high-precision clock for the IMS-LNO180. The microprocessor monitors the lock state of the PLL synchronization circuit and the warm-up phase of the oscillator and only enables the outputs after a successful phase synchronization. This state is also indicated by the four status LEDs (transition from red to green). In the phase synchronous state, the output level of the four outputs is monitored and in case of an error is signaled by the assigned red LED.

Compatibility
The IMS-LNO180 is an IMS module which is compatible with all systems of the IMS family. It can also be used on any slot (MRI, ESI, I/O).
