Meinberg
IMS-LIU
SKU: IMS-LIU
Line Interface unit
The LIU (Line Interface Unit) module generates different reference clock pulses which are derived from the GNSS-locked master oscillator of a preconnected satellite receiver. The output signals are available with high accuracy and stability therefore.
Key Features
- Synchronisation of telecom networks
- Synchronisation of transmitters/base stations (GSM / CDMA / UMTS / DAB / DVB)
- Clock and Framed telecom outputs
- Reference frequency delivered by preconnected GPS- or GLN-receiver
