NEC Toyocom TCO-6703N SC-cut 10MHz
Utilizing the Stress-Compensated (SC) crystal cut, this class of oscillator represents the very highest level of performance which is achievable with quartz-based oscillators. Featuring rapid warm-up and low power consumption, excellent short-term and long-term stability.
- Supply Voltage: 12V
- Power Consumption: 1A max (warm-up), 300mA typical (operating)
- Output: 5V CMOS Compatible
- Temperature Stability: +/-2.5x10^-9
- Ageing: +/-2x10^-10 (per day), +/-3x10^-8 (per
year)
- Frequency trim: +/-0.3ppm (0-5V)
