The 625L3I003M68640 is a CTS Model 625 HCMOS clock oscillator designed for low-cost, ultra-low voltage applications requiring excellent stability and low phase jitter performance. It supports multiple supply voltages (1.8V, 2.5V, and 3.3V) with a frequency range from 1.0 to 160 MHz, housed in a compact ceramic surface mount package measuring 2.5 × 2.0 × 1.0 mm. The device features HCMOS output with output enable functionality, operating temperature range from -40°C to +105°C, and typical phase jitter of 0.5 ps RMS (bandwidth 12 kHz to 20 MHz). Common applications include IoT/IIoT devices, microcontrollers, FPGAs, wireless communication systems, networking equipment, and portable devices where low power consumption and reliable clock generation are essential.
