SMD2520 26MHz VCTCXO

Nominal Frequency: 26MHz
Frequency Stability: ±0.5ppm @ -30~85℃
Operating Temperature Range: -40~85℃
Aging: ±1ppm

26.000 MHz VCTCXO - SMD 2520 (±0.5ppm, Clipped Sine Wave)

The 26MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is engineered for ultra-high stability and precision. Housed in a miniature 2520 SMD package (2.5mm x 2.0mm), it delivers exceptional ±0.5ppm frequency stability over an extended temperature range of -30°C to +85°C (and operational up to -40°C).

This high-performance oscillator is optimized for GPS/GNSS, telecommunications, and wireless communication systems that require a low-jitter, stable clock source with a Clipped Sine Wave output.
