The ECS-2520MVQ-250-BS-TR is a miniature SMD HCMOS crystal oscillator with MultiVolt™ capability designed for low-power and portable applications. It features a compact 2.5 × 2.0 × 0.8 mm ceramic package with a 25.000 MHz output frequency and operates across a supply voltage range of 1.6 to 3.6 V, compatible with 1.8 V, 2.5 V, and 3.3 V power supplies. The oscillator delivers exceptional performance with frequency stability of ±50 ppm over the -40°C to +85°C operating temperature range, phase jitter of 1 ps (12 kHz to 20 MHz), and a maximum startup time of 10 ms. With low current consumption (8 mA at 1–10 MHz), RoHS compliance, and AEC-Q200 qualification, this device is ideal for LoRa WAN, industrial, and automotive applications requiring reliable frequency generation in space-constrained designs.
