SiT5156

Exceptional dynamic stability under airflow, fast temp. ramp

• ±500 ppb over-temp. stability
• 3e-11 ADEV at 10 second average time
• ±15 ppb/°C frequency slope (ΔF/ΔT), 10 °C/min ramp
  • Enables fastest satellite lock under any operating conditions

20x better phase noise under vibration

• Minimizes loss of satellite lock in high-vibration environments

No activity dips or microjumps

• Eliminates the need for costly screening or burn-in test

0.2 ps/mV power supply noise rejection (PSNR)

• Reduces BOM by eliminating a dedicated LDO for the TCXO

LVCMOS or Clipped sinewave output

• Optimize for best balance between EMI and jitter

Rich programmable features

• Any frequency between 1 to 60 MHz
• ±0.5 ppm, ±1 ppm, ±2.5 ppm
• 2.25 to 3.63 V
• Large pull range from ±6.25 to ±3200 ppm:
  • Customize TCXO specifications for optimal system performance

Digital frequency tuning through I2C

• Eliminate frequency shift caused by board noise

Superior reliability

• 1 billion hours MTBF
• Lifetime warranty: Reduces repair costs and field failures due to clock components
