SiT7111AI-KY033IX-A10.000000

Benchmark holdover in real world conditions for Assured PNT systems

• Less than 3.0 µs time error after 12 hrs without GPS synchronization
• 5E-12 ADEV at 10 second averaging time, up to 4X better than vibration-rated quartz OCXOs
• Up to 10X better aging with ±0.1 ppb/day aging

Ultra resilient operation in harsh environments

• Up to 70X better g-sensitivity than vibration rated quartz OCXOs
• ±1 ppb over-temp. stability from -40 to 95°C
• ±0.01 ppb/°C frequency slope (ΔF/ΔT)
• 20,000 g shock survivability

Lower size, weight, and power (SWaP)

• Up to 3X lower power at 420 mW typical power consumption (3.3 V)
• Up to 20X less volume in a robust 9.0 x 7.0 x 3.6 mm package
• Up to 300X less weight at 0.35 g

Best phase noise under vibration

• Minimizes link drops in high-vibration environments

No activity dips or microjumps

• Reduces need for costly screening or burn-in tests

On-chip power-supply noise filtering for excellent PSNR

• Reduces BOM by eliminating a dedicated LDO for OCXO

LVCMOS or clipped sinewave output

• Optimizes for best balance between EMI and jitter

Rich programmable features

• Any frequency between 10 to 60 MHz
• 2.5, 2.8, and 3.3 V power supply options

Digital frequency tuning through I2C and SPI

• Large pull range from ±3.125 to ±400 ppm
• 5E-14 frequency pull resolution
