About
GDP Space’s Bit Synchronizers are crucial components in telemetry ground stations, engineered to reconstruct input data streams and recover the clock with the highest fidelity. This capability allows processing systems to extract the most meaningful information from received signals. A key differentiator is their performance, which is better than 1dB from theory down to –3dB Eb/No, even at input signal levels as low as 100mV. This superior performance significantly reduces lock dropouts in downstream frame synchronizers and decommutators, leading to more usable data during receiver fade and multi-path situations, which are common during critical mission phases like aircraft test maneuvers. The products are designed to address real-world data integrity issues, particularly those related to jitter, which adversely affects data recovery. GDP Space emphasizes that static bit error rate tests do not adequately evaluate bit synchronizers under real-world conditions, and offers the GDP Model 650 Bit Error Rate Test Set with a jitter test option for proper evaluation. The product line includes various configurations such as multi-channel rackmount units and PCI cards, supporting data rates from 10 bps to over 40 Mbps. Specific models include the Model 2265 Multi-Channel PCM Bit Synchronizer (up to 4 channels in a 2U chassis), Model 2365A Multi-Channel PCM Bit Sync (up to 8 channels in a 4U chassis with local control interface), Model 2430D (offering flexible signal I/O configurations), Model 270 Multi-Channel Bit Synchronizer (8 or 16 channels with Digital I/O), Model BSM202 (Dual Channel PCM Bit Sync on a single PCI card), and Model 2265EC (a stand-alone bit synchronizer and data encapsulator for diversity combiner products, housing up to 4 channels in a 2U chassis with optimized digital design for high performance).
