FAQ
Q1: What are the key features and typical applications of Suzhou Hangjing's CMOS TCXO Oscillator 2520 TC22H4 Series?
A: While specific data for the TC22H4 is not available in the search results, typical 2520-sized CMOS TCXOs offer features like high frequency stability (e.g., ±2 ppm to ±3 ppm over -40°C to +105°C), low power consumption, and a compact form factor (2.5mm x 2.0mm). They are commonly used in applications requiring precise timing, such as 5G communication equipment, GPS/GNSS receivers, IoT devices, and high-speed data transmission systems.
Q2: What about phase noise performance?
A: Phase noise is crucial for communication systems. High-quality TCXOs typically exhibit excellent phase noise, for example, -145 dBc/Hz at 1 kHz offset might be achievable in some models. Lower phase noise helps reduce bit errors in data links.
