The MAX7375 is a silicon oscillator produced by MAXIM. It is used as the clock source for microcontrollers and UARTs in 3V, 3.3V, and 5V applications. It has high resistance to vibration and EMI, and can work in a wide range of temperatures.
The MAX7375 silicon oscillator replaces ceramic resonators, crystals, and crystal oscillator modules as the clock source for microcontrollers and UARTs in 3 V, 3.3 V, and 5 V applications. It is supplied at specific factory‑trimmed frequencies, provides a rail‑to‑rail 50 % duty‑cycle square‑wave output, and is highly resistant to vibration, shock, and EMI, making it suitable for home‑appliance and automotive environments.
Key features include a 3‑pin SC70 package, +10 mA output drive current, 2 % initial frequency accuracy, ±50 ppm/°C temperature drift, fast 5 ns rise time, and very low jitter (160 ps p‑p at 8 MHz). The device operates from 2.7 V to 5.5 V, supports temperatures from –40 °C to +125 °C, and requires no external components for frequency setting.
