Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct voltage and tolerance specifications. Confirm that the 4-SMD no-lead footprint matches the target PCB layout dimensions. Check for RoHS compliance status if required by project regulations. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Oscillators Selection Notes

Select this component when a small form factor oscillator is required for 40 MHz applications. The 1.8V supply voltage makes it suitable for modern low-power digital systems. Consider the ±50 ppm stability requirement against the system's jitter tolerance. The enable/disable pin allows for power management strategies in battery-operated devices.

Oscillators Part Context

This part belongs to the TXC standard clock oscillator series, which provides reliable timing solutions for various electronic applications. The 7C series is characterized by its small footprint and CMOS output, making it a common choice for space-constrained designs. It complements larger through-hole or leaded packages by offering a modern surface-mount alternative.

Oscillators Replacement Considerations

Direct substitutes include other 40 MHz CMOS oscillators from TXC with identical pinouts and electrical characteristics. Verify that any replacement maintains the same 1.8V supply requirement and ±50 ppm stability. Cross-reference the mechanical dimensions to ensure compatibility with existing footprints.
