SIT8008BI-22-33S-4.294400

Oscillators Overview

The SiT8008BI-22-33S-4.294400 is a MEMS oscillator from the SiT8008B series, operating at 4.2944 MHz with ±20 ppm frequency stability. It functions within a -40°C to +85°C temperature range and supports a 3.3V supply voltage (2.97V to 3.63V). The device features LVCMOS/HCMOS output formats, draws 4.5 mA current, and includes a standby power-down function. Packaged in a 3225 SMD form factor (3.2mm x 2.5mm), it offers a maximum duty cycle of 55%.

Oscillators Feature Summary

• MEMS-based programmable oscillator technology providing high reliability
• Integrated standby mode for power-down functionality
• Supports both LVCMOS and HCMOS output signal formats

Oscillators Applications

• General timing solutions requiring low power consumption
• Embedded systems utilizing 3.3V logic interfaces
• Industrial applications operating across extended temperature ranges

Oscillators Procurement Notes

Verify the specific suffix 'S' indicates bulk packaging rather than tape-and-reel when reviewing distributor listings. Confirm the exact frequency tolerance of ±20 ppm matches system requirements. Ensure the 3225 package dimensions align with PCB footprint constraints. Cross-reference the AEC-Q100 qualification status if automotive compliance is mandatory for the target application environment.

Oscillators Selection Notes

Select this component when a stable 4.2944 MHz reference is required with minimal power draw. The ±20 ppm stability suits standard digital communication protocols. Consider the 3.3V operating voltage compatibility with existing logic levels. The standby feature enables dynamic power management strategies. Evaluate the 3225 package size against available board real estate compared to other MEMS oscillator options.

Oscillators Part Context

This part belongs to the SiT8008B family of low-power MEMS oscillators. The series is characterized by wide frequency tunability and robust performance across industrial temperature extremes. It serves as a silicon-based alternative to traditional quartz crystals, offering superior shock resistance and programmability without sacrificing frequency accuracy or phase noise performance.

Oscillators Replacement Considerations

Direct substitutes include other SiT8008 variants with matching 4.2944 MHz frequencies and 3225 packages. Verify equivalent stability ratings and output drive strengths before substitution. Check for identical voltage supply requirements to ensure circuit compatibility.
