CB3-3I-18M4320 is a low-cost, low-voltage HCMOS/TTL clock oscillator designed for precision timing applications in microcontrollers, FPGAs, and communication systems. This ceramic surface mount oscillator operates at 3.3V supply voltage with an industrial temperature range of -40°C to +85°C, delivering a fundamental frequency of 18.192 MHz with ±50 ppm frequency stability. The device features HCMOS output with tri-state enable function, output duty cycle of 45–55%, and typical phase jitter of 0.5 ps RMS (bandwidth 12 kHz–20 MHz), ensuring low-jitter performance for sensitive applications. The compact 7.0 × 5.0 × 1.8 mm package with tape and reel packaging makes it ideal for high-volume production in IoT, networking equipment, data communications, and test and measurement systems.
