Oscillators Procurement Notes

Verify the specific manufacturing lot date code and RoHS compliance status prior to procurement, as environmental regulations may vary by region. Confirm that the 1.8 V supply requirement aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout design guidelines provided in the official datasheet to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this component when a stable 14.31818 MHz reference is required for low-voltage digital systems. The ±25 ppm stability suits applications sensitive to clock drift but not requiring oven-controlled precision. The 1.8 V supply voltage makes it suitable for modern portable and battery-operated devices. Consider the 5.0x3.2 mm package size for space-constrained designs where surface mounting is preferred over through-hole alternatives.

Oscillators Part Context

This oscillator belongs to the 7CL series of standard clock oscillators from TXC Corporation. The series is characterized by its use of quartz or ceramic resonator elements combined with CMOS output drivers. These components are designed for general-purpose timing applications where moderate stability and wide temperature operation are necessary. The 7CL series supports various frequencies and supply voltages to accommodate diverse electronic system requirements.

Oscillators Replacement Considerations

Direct substitutes include other 14.31818 MHz CMOS oscillators with identical 1.8 V supply and ±25 ppm stability specifications. Verify pin compatibility and package dimensions when cross-referencing with alternative manufacturers. Ensure that any replacement part maintains the same operating temperature range and output drive strength to guarantee system reliability.
