The ECS-2520MVLC-049-BN-TR is a miniature SMD low current CMOS crystal oscillator featuring MultiVolt capability across 1.6 to 3.6 V supply voltage range, housed in a compact 2.5 × 2.0 × 0.8 mm ceramic package. This device operates at a frequency of 4.9152 MHz with frequency stability of ±50 ppm over the temperature range of -40°C to +85°C, delivering low phase jitter of 150 fs (typical) and a maximum rise/fall time of 7 ns. The oscillator exhibits extended temperature range operation, low current consumption (maximum 2.4 mA at 1.8 V for frequencies =20 MHz), and is compatible with 1.8 V, 2.5 V, and 3.3 V power supplies. Ideal for LoRa WAN, low power portable devices, industrial applications, and IoT systems requiring reliable, compact timing solutions.
