Note #1: With an effective loop capacitance of 4.0pF, the oscillator circuit will be within set-tolerance specification; less any frequency shift due to the reflow process.
Note #2: The oscillator loop needs to present an effective loop capacitance of 4.0 pF to track the stand-alone crystal frequency. This loop capacitance is essential to ensure highest
possible Closed-Loop Safety Factor for the entire population of crystals.
Note #3: Ts = - (C1) / [ 2*(C0 + CL)2 ] ………. Where CL = 4pF
• Exceptionally low plating load of 4.0pF, ideal for wearables,
wireless, and IoT applications
• Simultaneously optimized for ESR over extended operating
temperature range
• Miniature 1.6 x 1.0 x 0.5 mm SMD package, ideally suited
for space constrained designs
• Available with ±20 ppm set tolerance
• Seam sealed package for long term reliability
• Wearables
• Wireless Modules
• Internet of Things (IoT)
• Bluetooth/Bluetooth Low Energy (BLE)
• Machine-to-Machine (M2M) Connectivity
• Ultra Low Power MCU
• Near Field Communication (NFC)
• ISM Band Applications
• Ultra low power, energy saving MCU
