CX1255GB-3.9825MHZ-G7297

The CX1255GB-3.9825MHZ-G7297 is a high-precision crystal oscillator utilizing quartz crystal technology, designed for applications in communication and industrial control systems. It operates at a nominal frequency of 3.9825MHz and is housed in a metal package, providing good electromagnetic shielding and mechanical protection.

Key features include excellent frequency stability, typically ±50ppm over a wide operating temperature range of -40°C to +85°C. It also boasts superior phase noise performance, usually below -120dBc/Hz at a 1kHz offset, and a low operating current typically under 10mA, making it suitable for battery-powered devices. Vibration sensitivity is typically less than 1ppb/g.

This oscillator is well-suited for industrial control systems such as PLCs, motion controllers, and instrumentation requiring precise timing. It can also serve as a reference clock in communication equipment for RF modules or baseband processing. Maintenance requires avoiding mechanical shock and excessive vibration, with recommended soldering temperatures not exceeding 260°C for more than 10 seconds. Long-term storage should be in humidity below 60% RH.
