7CZ-32.768KDA-T

Oscillators Overview

The 7CZ-32.768KDA-T is a standard clock oscillator manufactured by TXC Corporation, designed for precise timing applications. It operates at a nominal frequency of 32.768 kHz using a quartz or ceramic resonator element. The device features a CMOS output type and requires a supply voltage of 1.8V. It includes an enable/disable control function for power management. The unit is housed in a compact 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm. Frequency stability is rated at +/-25ppm within the operating temperature range of -10°C to +70°C.

Oscillators Feature Summary

• CMOS output signal generation for digital logic interfacing
• Integrated enable/disable functionality for power optimization
• Compact surface-mount package design for space-constrained layouts

Oscillators Applications

• Real-time clock circuits in portable electronics
• Low-power embedded system timing references
• Battery-operated devices requiring precise timekeeping

Oscillators Procurement Notes

Verify component authenticity through authorized distributors. Confirm that the specific suffix matches the required voltage and tolerance specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Check for recent production change notices regarding material updates. Validate supply chain sources to avoid counterfeit components.

Oscillators Selection Notes

Select this model when a 1.8V supply voltage is mandatory for the target application. Consider the +/-25ppm stability requirement against environmental temperature variations. Evaluate the need for active enable/disable controls versus always-on oscillators. Compare physical dimensions against available board space constraints. Assess power consumption levels relative to battery life requirements.

Oscillators Part Context

This component belongs to the 7CZ series of standard clock oscillators from TXC Corporation. The series offers various voltage options and stability grades. The 7CZ-32.768KDA-T specifically targets low-voltage applications compared to other variants like the 7CZ-32.768KBA-T which supports 3.3V. It serves as a critical timing source for microcontrollers and communication interfaces.

Oscillators Replacement Considerations

The 7CZ-32.768KBD-T is listed as obsolete with the 7CZ-32.768KBA-T recommended as a substitute. However, the KBA-T variant operates at 3.3V, not 1.8V. Verify if the system can tolerate the higher voltage or if a different 1.8V alternative is required.
