Oscillators Procurement Notes

Verify current availability status as this specific part number is listed as obsolete in official manufacturer records. Confirm compatibility with existing circuit designs before procurement, as end-of-life products may require immediate substitution planning. Ensure that any alternative sourcing channels provide genuine components with verified authenticity to prevent performance degradation in critical timing applications.

Oscillators Selection Notes

Select this component when a 19.44 MHz reference with voltage control capability is required. The CMOS output simplifies board layout by removing analog filtering requirements associated with sine wave outputs. Consider the obsolete status during initial design phases; if active production is mandatory, evaluate equivalent VCXOs from the same manufacturer series or compatible alternatives with matching pin configurations and electrical specifications.

Oscillators Part Context

This oscillator belongs to Taitien's VTEU series of voltage-controlled crystal oscillators. The series supports various frequencies and output types, catering to diverse timing needs in consumer electronics and industrial applications. Taitien has specialized in quartz frequency control components since 1976, offering a broad range including TCXOs, OCXOs, and atomic clocks for aerospace and commercial markets.

Oscillators Replacement Considerations

Official documentation lists this part as no longer manufactured. Designers should consult Taitien's current product portfolio for direct replacements within the VTEU series or similar VCXO families. Verify that substitute parts match the 19.44 MHz frequency, 3.3V supply, and CMOS output requirements to ensure seamless integration without redesigning surrounding circuitry.
