12.95129

Overview

The Geyer Electronic America, Inc. model 12.95129 is a ceramic surface-mount oscillator operating at a frequency of 27 MHz. It utilizes HCMOS output signals and supports a supply voltage range of -0.5V to 7V. The device features tri-state functionality for output enable control. Electrical specifications include a maximum supply current of 11mA and a disabled current of 50µA. Frequency stability is rated at ±50ppm. The component operates within a temperature range of -40°C to 85°C. It is housed in a compact 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm x 0.80mm.

Feature Summary

• Generates stable 27 MHz clock signals using HCMOS logic levels
• Includes tri-state output capability for system power management
• Operates reliably across industrial temperature ranges

Applications

• Embedded systems requiring precise timing references
• Communication modules utilizing standard crystal oscillators
• Industrial control equipment needing robust frequency sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tolerance options. Confirm that the required frequency stability and load capacitance match the target circuit design. Check for any recent updates to the pinout or electrical characteristics before finalizing procurement. Ensure compatibility with the intended supply voltage range and logic family requirements.

Selection Notes

Select this component when a 27 MHz HCMOS signal is required in a small form factor. Consider the ±50ppm stability requirement against the application's timing sensitivity. Evaluate the -0.5V to 7V input range for flexibility in power supply design. Compare the 11mA active current consumption against other low-power alternatives if energy efficiency is critical.

Part Context

This part belongs to the KXO-V96 series of ceramic SMD oscillators from Geyer Electronic. These devices are designed for general-purpose timing applications where size constraints are significant. The series offers various frequencies and packages to suit different embedded electronics needs.

Replacement Considerations

Cross-reference with other 27 MHz HCMOS oscillators in 4-SMD packages. Verify pin-to-pin compatibility and identical electrical parameters such as voltage range and current consumption before substitution.
