Description
The GDP Model 2265EC Multi-Channel PCM Bit Synchronizer / Encapsulator houses up to 4 high performance bit synchronizer channels in a 2U chassis. The optimized digital design of this unit affords the highest performance characteristics currently available. This unit can be used as a stand-alone bit synchronizer and as a data Encapsulator for the GDP Diversity Combiner / Best Source Selector products.
The Model 2265EC is capable of maintaining synchronization with the signal of interest down to –3 dB Eb/No at signal levels down to 100mVpp. When searching for the signal, acquisition is attainable in less than 50 bits. The unit is very robust and can maintain synchronization for a period of at least 256 bit periods without a transition.
