Oscillators Procurement Notes

Verify the specific suffix codes against official SiTime documentation to confirm exact electrical parameters and package variations. Ensure the selected variant matches the required supply voltage and output logic levels for your circuit design. Cross-reference the part number with authorized distributors to confirm availability and authenticity before placing orders.

Oscillators Selection Notes

Select this component when a direct replacement for quartz oscillators is needed without redesigning the PCB footprint. Consider the ±20 ppm stability requirement and the -40°C to +85°C operating range. Ensure the 3V supply voltage aligns with the system power architecture. Verify that the SMD3225-4P package fits within the available board space constraints.

Oscillators Part Context

This part belongs to the SiT1602B series of low-power MEMS oscillators from SiTime. The series covers frequencies between 3.57 MHz and 77.76 MHz. These devices are designed to offer small size and low power consumption while maintaining high performance standards comparable to or exceeding traditional quartz timing components.

Oscillators Replacement Considerations

Officially documented as a 100% pin-to-pin drop-in replacement for quartz-based XOs. No additional external components are typically required for basic operation if replacing a standard XO.
