7CZ-32.768KBA-T

Oscillators Overview

The TXC Corporation 7CZ-32.768KBA-T is a standard clock oscillator operating at a nominal frequency of 32.768 kHz. It utilizes a quartz or ceramic resonator element housed in a compact 5.0x3.2 mm surface-mount package with four leads and no lead design. The device operates on a single 3.3V supply voltage and outputs a CMOS signal compatible with standard logic families. Frequency stability is maintained within +/-25 ppm across the specified industrial temperature range of -10°C to +70°C. This component is designed for precise timing applications requiring low profile and reliable performance.

Oscillators Feature Summary

• Generates a stable 32.768 kHz clock signal using quartz or ceramic technology
• Outputs CMOS-compatible digital signals for direct interface with logic circuits
• Operates efficiently on a single 3.3V power supply rail
• Maintains frequency accuracy within +/-25 ppm over the industrial temperature range

Oscillators Applications

• Real-time clock (RTC) modules in consumer electronics
• Microcontroller system clock sources
• Industrial control board timing references
• Low-power embedded device synchronization

Oscillators Procurement Notes

Verify the specific output load requirements and supply voltage tolerance against the target circuit design before procurement. Confirm that the 3.3V operating range aligns with the system power architecture. Ensure the 5.0x3.2 mm footprint matches the PCB layout constraints. Check for any specific automotive or high-reliability certifications if the application demands them, as standard industrial grades may not suffice for extreme environments.

Oscillators Selection Notes

Select this component when a small form factor is critical for the design. It is suitable for applications requiring a fixed 32.768 kHz reference without the need for external tuning components. Consider the +/-25 ppm stability limit; if higher precision is required, alternative models with tighter tolerances should be evaluated. The CMOS output simplifies integration with standard digital interfaces compared to analog sine wave oscillators.
