Oscillators Procurement Notes

Verify the specific suffix 'CG' against the manufacturer's current datasheet to confirm the exact stability class and output waveform specifications. Ensure the 2.5V supply voltage aligns with the target circuit design before procurement. Cross-reference the 4-pin SMD footprint dimensions with the PCB layout to guarantee mechanical compatibility.

Oscillators Selection Notes

Select this component when superior frequency stability compared to standard quartz oscillators is required. The TCXO architecture compensates for environmental temperature changes, making it suitable for industrial or outdoor environments. Compare the ±0.5 ppm stability against system jitter requirements to ensure adequate performance margins.

Oscillators Part Context

This model belongs to the TXC controlled oscillator family, specifically engineered for enhanced accuracy over standard crystal units. It utilizes internal compensation mechanisms to maintain the 38.4 MHz frequency despite thermal fluctuations, distinguishing it from basic ceramic or quartz alternatives.

Oscillators Replacement Considerations

Direct substitutes include the 7L-38.400MCS-T, which shares similar electrical characteristics and form factor. Verify pinout compatibility and output waveform matching when swapping between these controlled oscillator variants.
