12.94338

Overview

The Geyer Electronic America, Inc. part number 12.94338 is a ceramic surface-mount oscillator designed for precise frequency generation in electronic circuits. This component operates at a standard frequency of 1.8432 MHz and utilizes CMOS or TTL output logic levels to ensure compatibility with a wide range of digital systems. It features a 3.3V supply voltage requirement and includes an enable/disable control function for power management flexibility. The device is housed in a compact 4-SMD, no-lead package, facilitating automated assembly and integration into space-constrained printed circuit boards while maintaining reliable signal integrity.

Feature Summary

• Integrated enable/disable functionality for efficient power management
• CMOS/TTL compatible output logic for broad system interoperability
• Ultra-miniature 4-SMD no-lead package design for high-density mounting

Applications

• Digital clock signal generation for microcontrollers
• Timing reference for communication interfaces
• System reset and watchdog timer circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging options. Ensure that the selected variant matches the required operating temperature range and load capacitance specifications for your application. Cross-reference the part number with authorized distributor catalogs to confirm availability and authenticity before placing orders.

Selection Notes

Select this oscillator when a stable 1.8432 MHz reference is needed in a small form factor. Consider the 3.3V supply constraint and the need for software-controllable shutdown via the enable pin. Evaluate the CMOS/TTL output swing against the input requirements of the downstream logic family to ensure proper signal transmission without additional buffering.
