CX910 Ultra-high stability and low phase noise crystal oscillator

Learn about our ultra-high stability and low phase noise crystal oscillators

The CX910 is a four-output, dual-temperature, highly stable crystal oscillator. It utilizes SC-cut high-precision crystals, a customized low-noise oscillation circuit, and a pure copper temperature control system. Its phase noise reaches -126dBc/Hz at 1Hz. Internal independent voltage regulation and separate temperature control effectively reduce interference. A multi-stage linear regulator reduces core power supply noise to the nanovolt level, significantly improving phase noise and short-term stability performance at 10MHz output. It is suitable for radar, electronic countermeasures, aerospace measurement and control, and standard phase noise measurement scenarios.
