Although this cutting process is highly complex, it enables the clock module to have superior phase noise and aging characteristics. With precise temperature control by the oven chamber, the crystal operates in a highly stable environment, effectively minimizing the impact of ambient temperature fluctuations on phase noise and jitter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"builder-block builder-4200fd2f9a8b4aa7bf100f67ef6cacee builder-has-component css-19ox3hq\"\u003e\n\u003ch6\u003eFour Independent Buffers. Synchronized Clock Outputs\u003c\/h6\u003e\n\u003cp\u003eThe SC-1 is equipped with four independent buffered clock outputs, all derived from the same source. While ensuring synchronized output, each output is equipped with its own buffering circuit, providing not only stable output impedance but also excellent driving capabilities. Whether using a single output or multiple outputs simultaneously, it delivers precise and stable performance, meeting your diverse requirements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"builder-block builder-3abe557463714afa8b24ec1e4750257e builder-has-component css-qc0lp8\"\u003e\n\u003cdiv class=\"builder-columns css-1fuo4gk\"\u003e\n\u003cdiv class=\"builder-column css-1lihfuk\"\u003e\n\u003cdiv class=\"builder-blocks builder-blocks-child css-h47494\"\u003e\n\u003cdiv class=\"builder-block builder-7492848f4b804fdc8a4d6a28feaa4650 builder-has-component css-19ox3hq\"\u003e\n\u003cp\u003e-118dBc\u003c\/p\u003e\n\u003ch6\u003eUltra-low Phase Noise\u003c\/h6\u003e\n\u003cp\u003eFor a clock source device, the output noise is closely related to the internal OCXO clock module. However, the actual output noise is not the same as the OCXO output noise, as the output buffering circuit introduces some performance loss. Therefore, phase noise at the output port of the device provides a more practical reference value. With the excellent design of SC-1, it achieves ultra-low phase noise of better than -118dBc at 1Hz frequency at the clock output ports, setting a new industry-leading standard and delivering purer, more stable clock signals.\u003c\/p\u003e\n\u003ch6\u003eClear Status Indication\u003c\/h6\u003e\n\u003cp\u003eThe SC-1 front panel features a warm-up status indicator LED. When the oven chamber is warming up, the indicator blinks; once the warm-up is complete, the indicator stays on. This simple and intuitive design allows you to instantly know the operating status of the device.\u003c\/p\u003e\n\u003ch6\u003eCustomizable Output Waveforms\u003c\/h6\u003e\n\u003cp\u003eWe offer two output waveform options: sine wave and square wave, catering to diverse device requirements or your demands. Square-wave output is particularly recommended, as it provides higher locking accuracy than sine-wave output, delivering a more precise clock signal.\u003c\/p\u003e\n\u003cdiv class=\"builder-block builder-cb208e0045c04a65b11667d0e542f0d5 builder-has-component css-19ox3hq\"\u003e\n\u003ch6\u003eConstant Performance\u003c\/h6\u003e\n\u003cp\u003eEven with the SC-1's precise clock system, slight drift or deviation over time is inevitable. To address this condition, we designed a 1PPS reference signal input terminal on the rear panel. When connected to an external second-based reference signal source, the device automatically performs calibration. The calibration status will be indicated by the LED on the front panel. What’s more, we offer free calibration services to ensure your device remains accurate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"builder-block builder-24be5b764df449188ac802b4ed4236a1 builder-has-component css-qc0lp8\"\u003e\n\u003cdiv class=\"builder-columns css-1fuo4gk\"\u003e\n\u003cdiv class=\"builder-column css-1lihfuk\"\u003e\n\u003cdiv class=\"builder-blocks builder-blocks-child css-h47494\"\u003e\n\u003cdiv class=\"builder-block builder-8d14a4bfbdba40ae9e625f1a24cb55d4 builder-has-component css-19ox3hq\"\u003e\n\u003ch6\u003eCBVB Vibration Absorption System\u003c\/h6\u003e\n\u003cp\u003eEquipped with Matrix Audio’s CBVB vibration absorption foot pads, the SC-1 effectively isolates external vibrations, minimizing interference and ensuring the clock remains in a stable operating state.
