SiTime recommends following a specific PCB layout guideline to minimize noise and ensure optimal performance. This includes using a dedicated power plane, keeping the oscillator away from high-frequency signals, and using a ground plane under the device. Refer to SiTime's application note AN-1001 for detailed guidelines.
The SIT1602BC-23-18E-33.333330 oscillator requires a 15pF load capacitance on each output pin to ensure proper termination. This can be achieved by adding external capacitors or using a PCB layout that provides the necessary capacitance.
While the datasheet specifies an operating temperature range of -40°C to 85°C, SiTime recommends derating the oscillator's frequency stability and jitter performance at extreme temperatures. Consult SiTime's application notes for more information on temperature derating.
The SIT1602BC-23-18E-33.333330 oscillator is designed to operate in environments with moderate vibration. However, for high-vibration applications, SiTime recommends using their vibration-resistant oscillators, such as the SIT1602BC-23-18E-33.333330-VR, which are specifically designed to withstand extreme vibration.
To troubleshoot frequency accuracy issues, check the oscillator's power supply voltage, ensure proper termination, and verify that the PCB layout follows SiTime's recommended guidelines. If issues persist, consult SiTime's application notes or contact their technical support for assistance.
