ACZ-32.768KBE-T

Oscillators Overview

The ACZ-32.768KBE-T is a standard CMOS crystal oscillator manufactured by TXC Corporation, designed for precision timing applications. It operates at a nominal frequency of 32.768 kHz with a frequency stability of ±50 ppm. The device requires a 3.3V supply voltage and features an Enable/Disable control function for power management optimization. Housed in a compact 4-SMD, No Lead surface-mount package, it supports industrial temperature ranges suitable for embedded systems requiring reliable low-frequency clock signals.

Oscillators Feature Summary

• Integrates an Enable/Disable pin to allow dynamic power control and standby mode operation
• Utilizes CMOS output logic for direct interfacing with digital logic circuits
• Provides stable 32.768 kHz timing reference for real-time clock synchronization

Oscillators Applications

• Real-Time Clock (RTC) modules in consumer electronics
• Embedded microcontroller system clocks
• Low-power IoT sensor nodes

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 3.3V supply rail meets the current consumption specifications during active and disabled states. Ensure PCB layout adheres to the recommended footprint dimensions for the 4-SMD No Lead package to maintain signal integrity and mechanical reliability.

Oscillators Selection Notes

Select this component when a fixed 32.768 kHz frequency is required with minimal design complexity compared to discrete crystals. The integrated enable feature offers superior power efficiency over passive solutions in battery-operated devices. Consider the ±50 ppm stability tolerance against application drift requirements. This oscillator simplifies BOM count by combining the resonator and driver circuit into a single surface-mount unit.

Oscillators Part Context

This part belongs to the ACZ series of standard clock oscillators from TXC Corporation. It serves as a drop-in replacement for designs previously using discrete quartz crystals and external oscillator circuits. The series targets cost-sensitive applications where space constraints and power consumption are critical factors in product design.

Oscillators Replacement Considerations

Cross-reference with other TXC 32.768 kHz oscillators such as AWZ or ACZ variants for pin-compatible upgrades. Verify that substitute parts match the 3.3V supply voltage and CMOS output logic levels. Check if alternative models offer tighter frequency stability or extended temperature ranges if the original specification is insufficient.
