Exceptional dynamic stability under airflow, fast temp. ramp
- ±5 ppb over-temp. stability from -40°C to 95°C
- ±0.3 ppb/°C frequency slope (ΔF/ΔT), 10°C/min ramp, ensures performance under fast temp. transients
- ±150 ppb 20-year aging, 16x better than quartz, eliminates in-factory calibration required with less stable devices
- 1.5e-11 ADEV at 10 second averaging time
40% smaller and 2x lower power than comparable OCXOs
- 110 mW typical power consumption (2.5V)
- Robust 7.0 mm x 5.0 mm ceramic package, insensitive to board bending stress, reducing PCB layout constraints
- Ideal for replacing larger power-hungry quartz OCXOs
Better acceleration sensitivity and 20x better phase noise under vibration
- 0.01 ppb/g g-sensitivity, per IAW MIL-PRF-55310 section 4.18.8.3.1
- Minimizes packet loss in high-vibration environments
No activity dips or microjumps
- Eliminates any need for costly screening or burn-in tests
0.2 ps/mV power supply noise rejection (PSNR)
-
Reduces BOM by eliminating a dedicated LDO for TCXO
LVCMOS or clipped sinewave output
- Optimize for best balance between EMI and jitter
Programmable features
- Any frequency between 1 to 60 MHz
- 2.25 to 3.63 V
