12.95

Overview

The Geyer Electronic America, Inc. model 12.95066 is a ceramic surface-mount oscillator (XO) operating at 27 MHz with HCMOS output. It features a frequency stability of ±50 ppm and operates within a supply voltage range of -0.5V to 7V. The device supports tri-state output enable functionality and draws a maximum supply current of 11 mA. It is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a maximum height of 0.80mm. The component functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Generates stable 27 MHz clock signals using internal crystal resonance
• Provides programmable tri-state output control for system power management
• Delivers standard HCMOS logic levels for direct digital interface compatibility

Applications

• Embedded microcontroller clock generation
• Industrial communication bus synchronization
• Consumer electronics timing circuits

Procurement Notes

Verify the complete part number suffix when ordering, as packaging options such as tape-and-reel or cut-tape may vary by distributor. Confirm that the specific revision matches the required electrical characteristics. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Cross-reference the datasheet version to validate performance parameters against current manufacturing standards before finalizing purchase orders.

Selection Notes

Select this component when a fixed-frequency 27 MHz source is required for digital logic interfacing. The HCMOS output level suits standard CMOS-based circuitry without additional buffering. Consider the wide supply voltage tolerance if the target system experiences voltage fluctuations. Evaluate the thermal range requirements to ensure operation within the specified -40°C to 85°C limits for the intended environment.

Part Context

This oscillator belongs to the KXO-V96 series from Geyer Electronic America, designed for general-purpose timing applications. It replaces discrete crystal and amplifier configurations with a single integrated solution. The series emphasizes reliability and compact form factors suitable for modern PCB layouts requiring precise frequency control without external tuning components.

Replacement Considerations

Direct substitutes must match the 27 MHz frequency, HCMOS output type, and 4-SMD package dimensions. Verify equivalent supply voltage ranges and current consumption profiles. Check for compatible frequency stability ratings and operating temperature specifications to ensure functional parity in existing designs.
