Oscillators Procurement Notes

Verify the specific suffix 'S' indicates Standby (Power Down) functionality as documented in distributor descriptions. Confirm the 7x5mm package dimensions match your PCB footprint requirements. Ensure the 1.8V supply voltage aligns with your system's power rails. Check RoHS compliance status through official manufacturer documentation before finalizing procurement.

Oscillators Selection Notes

Select this component when a 37.5 MHz frequency with 10 PPM stability is required. The 7x5mm package offers a larger form factor compared to smaller MEMS options. Consider the 29 mA current consumption against power budget constraints. Verify compatibility with LVCMOS/LVTTL interfaces in the target circuit design.

Oscillators Part Context

This part belongs to the SiT8208 family of MEMS oscillators from SiTime. The series provides various frequencies and packages. The 'AI' designation typically refers to specific grade or configuration within the product line. Similar parts in the series include variants with different frequencies like 50 MHz or other package sizes such as 2520 or 3225.

Oscillators Replacement Considerations

Direct substitutes may include other SiT8208 variants with identical 37.5 MHz frequency and 7x5mm package. Cross-reference with SiTime's replacement tool for exact pin-compatible alternatives. Ensure any substitute matches the 10 PPM stability and LVCMOS/LVTTL output requirements.
