PRS10 Rb Oscillator Clock Outputs X Clock Outputs CG792 Clock Synthesizer In communications systems and networks, jitter, wander, or frequency offsets can lead to high bit error rates or total loss of synchronization. The CG792 provides exceptionally clean, stable clocks required for the most critical applications while setting new standards for frequency accuracy, phase noise performance, and operational flexibility. Advanced New Architecture At the heart of the CG792 lies a sophisticated dual analog PLL architecture utilizing state-of-the-art reference synthesizer phase locked loops. This design employs intelligent spur avoidance algorithms that automatically select optimal reference frequencies to eliminate integer boundary spurs. The system automatically chooses between several precision reference frequencies to maximize phase detector frequency while minimizing spurious content, maintaining decimal frequency resolution with seamless frequency transitions. Phase Noise X Phase Noise for 10 MHz Clock Output CG792 Clock Synthesizer Phase Noise for 10 MHz Clock Output Precision Timebase Options The CG792 accommodates diverse timing requirements with multiple timebase configurations. The standard crystal timebase provides excellent stability, while optional OCXO or rubidium frequency standards offer higher precision for demanding measurements. An external 10 MHz reference input with automatic detection ensures compatibility with existing laboratory standards. Each channel provides three synchronized outputs optimized for different applications. High-speed differential outputs provide square waves with programmable offset and amplitude and sub-100-picosecond transition times. The CMOS output delivers fixed 3.3 V logic levels optimized for high-impedance loads . Low Phase Noise and Jitter Allan Deviation X Allan Deviation CG792 Clock Synthesizer With exceptionally low phase noise and high frequency resolution, the CG792 can replace RF signal generators in many applications. Front-panel outputs provide square waves up to +7 dBm — ideal for driving RF mixers. Advanced Phase Control and Synchronization The CG792's built-in phase measurement system enables automatic channel synchronization. Hardware-based channel coupling establishes deterministic phase relationships, while fast phase slew enables rapid timing adjustments. Comprehensive Modulation Capabilities The built-in modulation system supports both phase and frequency modulation using a range of standard built-in waveforms as well as a user-applied analog signal via the rear-panel BNC input. In Jitter mode, the clock edges can be modulated with up to 3 ms of jitter. Additional capabilities include output blanking, polarity inversion, and pseudo-random bit sequence generation.
