Oscillators Procurement Notes

Verify the complete part number including the trailing 'E' suffix, which indicates specific environmental or packaging configurations. Confirm that the 16 MHz frequency matches the target system clock requirements. Ensure the 1.8 V to 3.3 V supply voltage aligns with the host circuit's power rails. Check for RoHS compliance documentation if required by regional regulations. Validate the 4-SMD package footprint against the design schematic.

Oscillators Selection Notes

Select this component when a balance between low power consumption and moderate frequency stability is required. The ±50 ppm stability is sufficient for many general-purpose digital interfaces but may not suit high-precision RF applications. Consider the 16 MHz frequency for standard microcontroller clocks or communication buses. The wide supply voltage range simplifies power management across different system architectures.

Oscillators Part Context

This model belongs to the SiT8008B series, a family of low-power programmable oscillators designed for cost-sensitive and space-constrained applications. The series leverages silicon MEMS technology to replace traditional quartz crystals, offering improved reliability and design flexibility. The BI suffix typically denotes industrial temperature grade and specific performance characteristics within the broader product line.

Oscillators Replacement Considerations

Direct replacements must match the 16 MHz frequency, 4-SMD package, and LVCMOS/HCMOS output. Verify that substitute components support the same 1.8 V to 3.3 V supply range and -40°C to +85°C operating temperature. Cross-reference pinouts and electrical characteristics to ensure compatibility with existing PCB layouts and system timing requirements.
