12.90344

Overview

The Geyer Electronic America, Inc. model 12.90344 is a ceramic surface-mount oscillator operating at a fundamental frequency of 4 MHz. It utilizes HCMOS output logic and supports an enable/disable control function via a tri-state interface. The device operates within a supply voltage range of -0.5V to 7V and draws a maximum supply current of 11mA during active operation. It features a frequency stability of ±50ppm and functions reliably across a temperature range of -40°C to 85°C. The component is housed in a compact 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm.

Feature Summary

• Provides stable 4 MHz clock signals using HCMOS output technology for digital circuit synchronization.
• Includes an enable/disable pin allowing dynamic power management through tri-state control.
• Designed for robust performance in industrial environments with wide temperature tolerance.

Applications

• Microcontroller clock source generation
• Digital signal processing timing references
• Communication interface synchronization

Procurement Notes

Verify the specific ordering suffix required for your packaging needs, such as tape and reel or cut tape options, when placing orders. Confirm that the selected variant matches the exact frequency and package requirements for your design. Ensure compliance with the manufacturer's specifications regarding supply voltage and thermal limits during integration.

Selection Notes

Select this component when a precise 4 MHz reference is required for HCMOS-compatible digital systems. Consider the enable/disable feature if power conservation is critical during idle states. Evaluate the small form factor against available board space constraints. Verify that the ±50ppm stability meets the timing accuracy requirements of the target application.
