CB3-3C-20M4800 is a low-cost, low-voltage HCMOS/TTL clock oscillator designed for applications requiring stable frequency generation. This device operates at 3.3V supply voltage with a frequency of 20 MHz and frequency stability of ±20 ppm over the temperature range of -20°C to +70°C. The oscillator features a ceramic surface mount package measuring 7.0 × 5.0 × 1.8 mm with tri-state output enable functionality, output duty cycle of 45–55%, and phase jitter of 0.5 ps RMS (typical). It is well-suited for microcontrollers, FPGAs, wireless communication systems, networking equipment, and data communications applications where reliable clock generation is essential.
