Bit Synchronizers

The PCM Bit Synchronizer is a key component in a telemetry ground station. It must reconstruct its input data stream and recover the clock with the highest fidelity to allow the processing system to produce meaningful information.

The most demanding users consider our bit synchronizers to be the GOLD Standard in the industry. GDP offers a series of bit synchronizers to satisfy a wide spectrum of applications. We offer units containing a single channel bit synchronizer or multi-channel synchronizers (up to 16). Optional features include: built in Simulator/PRN Generator, Forward Error Correction (Viterbi), Automatic bit rate detection, built in BERT, Quadrature signal handling (QPSK, AQPSK, SOQPSK, etc.), and in a multiple synchronizer configuration –Best Source Selection that produces a high fidelity output that is the best combination of bits from multiple sources (Also see Best Source Selectors). Why Buy GDP Bit Synchronizers
