7CZ-32.768KATF-T

Oscillators Overview

The 7CZ-32.768KATF-T is a standard clock oscillator manufactured by TXC Corporation, utilizing a quartz crystal resonator. It operates at a frequency of 32.768 kHz with CMOS output format. The device supports a supply voltage of 1.8V and offers a frequency stability of ±25 ppm across an operating temperature range of -40°C to +85°C. It features a compact surface-mount package measuring 5.0 mm in length, 3.2 mm in width, and a maximum height of 1.40 mm.

Oscillators Feature Summary

• Integrates a quartz crystal resonator for precise timing generation within a single surface-mount package.
• Provides a CMOS digital output signal suitable for direct interfacing with microcontrollers and logic circuits.
• Designed for low-power applications with a specified supply voltage of 1.8V.

Oscillators Applications

• Real-time clock (RTC) modules in portable electronics
• Microcontroller system clocks
• Low-frequency timing references in embedded systems

Oscillators Procurement Notes

Verify the specific suffix 'ATF' against official TXC documentation to confirm pinout configuration and electrical parameters, as suffixes often denote variations in tolerance or packaging. Ensure compatibility with the target board's 1.8V power rail and load capacitance requirements before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a low-profile, quartz-based oscillator is required for 32.768 kHz applications. The 1.8V supply requirement makes it suitable for battery-powered devices. Compare physical dimensions and thermal characteristics against alternative models in the 7CZ series to ensure mechanical fit and performance consistency.

Oscillators Part Context

This part belongs to the 7CZ series of standard oscillators from TXC Corporation. The series includes various variants differentiated by supply voltage, package size, and frequency stability. The 7CZ-32.768KATF-T specifically represents the 1.8V variant in the 5.0x3.2 mm form factor, distinct from higher voltage versions like the 3.3V 7CZ-32.768KBA-T.

Oscillators Replacement Considerations

The 7CZ-32.768KBD-T is listed as a discontinued part with the 7CZ-32.768KBA-T recommended as a manufacturer-recommended substitute. However, the KBA-T operates at 3.3V, requiring voltage level verification if used as a replacement for the 1.8V KATF-T model.
