This document describes the features and characteristics of ECLIPTEK CORP.'s EC25 series ceramic oscillators, including RoHS compliance, supply voltage, output type, stability, frequency range, etc.
The EC25 series is a ceramic surface‑mount oscillator offered by ECLIPTEK. It operates from a 5.0 V supply and provides HCMOS/TTL outputs with stability as tight as ±20 ppm depending on the selected option. The device is RoHS compliant and available in bulk or tape‑and‑reel packaging.
Key electrical parameters include a frequency range of 1.544 MHz to 106.250 MHz, operating temperature from –10 °C to +70 °C (standard) or –40 °C to +85 °C (extended), and output logic levels of 2.4 V DC (high) and 0.4 V DC (low). Mechanical dimensions, pin assignments and recommended solder pad layout are also provided for PCB designers. This manual is written in Chinese.
