SIT1602BC-21-25N-72.000000

Oscillators Overview

The SiTime SIT1602BC-21-25N-72.000000 is a MEMS-based programmable oscillator operating at 72 MHz with ±20 ppm frequency stability. It utilizes a 3225 (3.2mm x 2.5mm) surface-mount package and supports a supply voltage range of 2.25 V to 2.75 V, typically centered at 2.5 V. The device features LVCMOS/HCMOS output formats and operates within an industrial temperature range of -20°C to +70°C.

Oscillators Feature Summary

• MEMS technology provides robustness against shock and vibration compared to traditional quartz crystals
• Programmable architecture allows for custom frequency generation without mask set changes
• Low power consumption design suitable for battery-operated and portable applications

Oscillators Applications

• Industrial control systems requiring precise timing
• Portable consumer electronics needing small form factors
• Communication equipment utilizing standard clock frequencies

Oscillators Procurement Notes

Verify the specific ordering suffix 'N' and 'D' or 'X' in official datasheets to confirm tape-and-reel packaging and lead-free status. Ensure the voltage code matches the system's 2.5V requirement. Confirm the 3225 package dimensions align with PCB footprint constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a 72 MHz frequency is required with ±20 ppm stability. Choose over quartz alternatives if superior shock resistance and programmability are needed. Verify that the 3225 package size fits the design space and that the 2.5V supply rail is available on the target board.

Oscillators Part Context

This component belongs to the SiT1602 series of low-power MEMS oscillators. The series is characterized by its ability to generate various frequencies from a single platform, reducing inventory complexity. The BC variant indicates specific performance grades within the broader product line.

Oscillators Replacement Considerations

Direct replacements must match the 72 MHz frequency, 3225 package, and 2.5V supply. Cross-reference with other SiT1602 variants having different suffixes for minor parameter adjustments, but ensure functional equivalence in timing and electrical specifications.
