Product Description:
The 1000C from Microsemi Corporation achieves ultra-low phase noise, excellent short-term stability, and low aging rate through advanced SC and BVA crystal processing technology. It reaches the specified aging rate within 30 days of continuous operation, and even lower aging rates of 1E-12 can be achieved after years of continuous power-on operation.
The 1000C features a constant-temperature bath design with DuPont insulation technology, providing excellent temperature characteristics across the entire operating temperature range. The frequency change caused by temperature variations is <5.0E-9. Additionally, the 1000C includes a sensor for monitoring the temperature variation of the constant-temperature bath (monitoring sensitivity: 10mV/℃).
The 1000C is available in two versions: High-Performance and Ultra-High Performance. The Ultra-High Performance version achieves SSB phase noise of -130dBc@1Hz and -160dBc@100KHz. Once stabilized, the short-term stability can reach 2E-13 (0.1s ~ 100s). The High-Performance version also achieves SSB phase noise of -120dBc@1Hz and -160dBc@100KHz, with a short-term stability of 3E-13 (0.1s ~ 100s) once stabilized.
The 1000C provides four independent 5MHz outputs using low-noise, high-isolation buffer amplifiers. The buffer amplifiers isolate the signal output from the effects of load variations as much as possible. The internal voltage regulator effectively reduces the impact of power supply ripple. The servo loop system employs linear electronic frequency control technology for precise frequency adjustment, with adjustment linearity better than 5% within the voltage control range.
The 1000C meets the requirements of a wide range of military and industrial environments. It can be applied in high-precision frequency counters and synthesizers, GPS receivers, microwave multipliers, phase noise calibration test equipment, 2G communication applications, radar and tactical communication systems, secure communication systems, satellite ground terminals, and aerospace flight systems.
