SKU: Model 2265 Category:


The GDP Model 2265 Multi-Channel PCM Bit Synchronizer 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.

The Model 2265 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.
