10MHz Distribution-Amplifier for OCXO Frequency Standard 8 Port Output Signal Distribution System Architecture Dual Mode Input Redundancy Power Management Modular Expansion Interface(without OCXO)

10MHz Distribution-Amplifier for OCXO Frequency Standard 8 Port Output Signal Distribution System Architecture Dual Mode Input Redundancy Power Management Modular Expansion Interface(without OCXO)

• Frequency Standard: Built-in OCXO technology delivers exceptional ≤±50ppb frequency stability with -172dBc/Hz phase noise at 100kHz, featuring SC-cut and G-sensitivity compensation (0.3ppb/g) for reliable 10MHz reference signals in demanding laboratory and industrial measurement environments.
• Multi-Channel Distribution System: 8-port BNC/Q9 output configuration provides 1Vrms (13dBm) per channel with adaptive 50Ω/75Ω impedance matching, >40dB harmonic suppression, >70dB spurious rejection, and ≥60dB inter-channel isolation for simultaneous multi-instrument operation.
• Dual-Mode Input Architecture: Internal OCXO with external 10MHz reference backup (0.1-5Vpp range) features automatic priority switching and ±2ppb voltage/load stability, seamlessly transitioning to internal oscillator within 50ms if external signal anomalies occur.
• Robust Power Management: Wide DC 11.7-12.9V input tolerance with 15V surge protection, three-stage filtering design, 12W maximum consumption, and ±0.5dB output amplitude stability across -30°C to +70°C operating temperature range.
• Compact Modular Design: 63*43mm PCB with 100*55*120mm housing including BNC connectors, features expansion slot for GPSDO integration, I²C monitoring interface for oscillator aging tracking (±0.5ppb/30 days), and LED status indicators for power and fault detection.
