IMS-LNO
SKU: IMS-LNO
10 MHz sine low phase noise output module
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.
Key Features
- 4x sine outputs - 10 MHz or 5 MHz
- Four LEDs: Signal status at corresponding output
- Input: 10 MHz, sine (1Vpp min.) or TTL
- Output Level: 5 dBm +/- 1 dBm into 50 Ohm
- Option: LNO-8dB with 8 dBm output level or
- LNO-12dB with 12 dBm output level

| Further Information | Functionality
A high-quality oscillator is Synchronised 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 Synchronisation circuit and the warm-up phase of the oscillator and only enables the outputs after a successful phase Synchronisation. 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 signalled 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). |
