SIT8208AI-23-18E-33.300000

Oscillators Overview

The SiTime SIT8208AI-23-18E-33.300000 is a MEMS oscillator operating at 33.3 MHz with LVCMOS/LVTTL output formats. It functions within a supply voltage range of 1.71 V to 1.89 V and supports an Enable/Disable control feature. The device provides ±10 ppm frequency stability across the industrial temperature range of -40°C to +85°C. It utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm x 2.5 mm. Typical integrated RMS phase jitter is 500 fs (12 kHz to 20 MHz).

Oscillators Feature Summary

• Ultra-low phase jitter performance for high-speed data applications.
• Pin-to-pin drop-in replacement compatibility with legacy quartz oscillators.
• Configurable enable/disable functionality for power management.

Oscillators Applications

• SATA and SAS interfaces
• Ethernet connectivity
• PCI Express systems

Oscillators Procurement Notes

Verify the specific suffix '23' against official SiTime documentation to confirm the exact package outline and pinout configuration. Ensure the '18E' designation matches the required 1.8V supply voltage and industrial temperature grade for the target design environment. Confirm RoHS compliance status through the manufacturer's current material declaration.

Oscillators Selection Notes

Select this component when replacing standard quartz oscillators in space-constrained designs requiring 3.2x2.5mm footprints. Choose based on the need for precise 33.3 MHz timing with low jitter characteristics. Consider the 1.8V operating voltage and LVCMOS/LVTTL output levels for logic interface compatibility.

Oscillators Part Context

This part belongs to the SiT8208 series of ultra-performance MEMS oscillators from SiTime. The series offers frequencies from 1 to 80 MHz with industry-leading reliability metrics. It is designed to replace traditional quartz, SAW, and overtone oscillators while providing faster time-to-market through field programmability.

Oscillators Replacement Considerations

The SiT8208 series serves as a direct footprint-compatible replacement for legacy quartz, SAW, and overtone oscillators. Verify that the existing board layout accommodates the 4-SMD, No Lead package dimensions without modification.
