• Operates efficiently at low voltage with minimal current consumption
• Provides stable frequency performance across extended industrial temperature ranges

Oscillators Applications

• Real-time clock circuits in portable electronic devices
• Microcontroller system timing references
• Low-power embedded monitoring systems

Oscillators Procurement Notes

Verify the specific supply voltage requirement against the target circuit design, as this model operates at 1.8V rather than the common 3.3V variant. Confirm that the PCB footprint matches the 4-SMD, No Lead dimensions provided in the datasheet. Ensure the selected component meets the required ±50ppm stability tolerance for the intended application environment. Check for availability status as manufacturing cycles may vary.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is mandatory for the system power rail. Choose this model over higher voltage alternatives if space constraints require the small 5.0x3.2mm form factor. Consider the ±50ppm stability specification to ensure compatibility with the host controller's clock input requirements. Verify that the CMOS output type aligns with the receiving logic gate specifications.

Oscillators Part Context

This part belongs to the 7CZ series of standard clock oscillators manufactured by TXC Corporation. The series provides various voltage options, including 3.3V and 1.8V variants, to suit different power architectures. The 7CZ line is designed for applications requiring reliable timekeeping and system synchronization in compact consumer electronics and industrial equipment.

Oscillators Replacement Considerations

The manufacturer recommends the 7CZ-32.768KBA-T as a replacement. Note that the recommended alternative typically operates at 3.3V, which differs from the 1.8V supply of the 7CZ-32.768KDE-T. Verify voltage compatibility before substitution.
