Oscillators Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure component integrity. Confirm that the received units match the exact part number designation, as suffixes may indicate variations in packaging or testing standards. Ensure storage conditions comply with the specified MSL rating prior to soldering. Cross-reference the datasheet revision against the provided documentation to confirm all electrical characteristics remain unchanged. Validate that the supplier provides appropriate traceability documents for quality assurance purposes.

Oscillators Selection Notes

Select this component when a small form factor is required alongside robust performance in varying thermal conditions. The MEMS construction offers advantages in vibration resistance over ceramic alternatives. Consider the 3.3V supply requirement and CMOS output compatibility with the target digital logic family. The enable pin provides flexibility for system power sequencing. Evaluate the ±25ppm stability against the system's jitter tolerance requirements before finalizing the design choice.

Oscillators Part Context

This oscillator belongs to the TB series from TXC Corporation, which focuses on MEMS-based solutions for general-purpose timing applications. The series is designed to replace traditional quartz crystals in modern electronic devices where size and durability are critical. The TB-22.1184MBD-T specifically addresses the need for a 22.1184 MHz reference frequency, commonly used in telecommunications and serial data interfaces. It represents a shift towards silicon-based timing components for improved consistency.

Oscillators Replacement Considerations

Direct substitutes include other MEMS oscillators from TXC with identical frequency and package dimensions, such as variants within the TA or TD series if pinout compatibility allows. Cross-manufacturer replacements must match the 4-SMD no-lead footprint, 3.3V operation, and CMOS output type. Verify that alternative parts support the same enable/disable functionality and meet the -40°C to +85°C temperature range specification.
