12.95191

Overview

The Geyer Electronic America, Inc. model 12.95191 is a surface-mount HCMOS crystal oscillator operating at a fundamental frequency of 25 MHz. It features a standard output configuration with tri-state enable functionality and operates within a supply voltage range of -0.5V to 7V. The device consumes a maximum supply current of 11mA during active operation and reduces to 50µA in disabled mode. 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 unit supports an operating temperature range from -40°C to 85°C and maintains a frequency stability of ±50ppm.

Feature Summary

• Generates a stable 25 MHz clock signal using internal crystal resonance for precise timing applications
• Provides tri-state output control allowing the signal line to be electrically disconnected when not in use
• Supports wide supply voltage input ranging from -0.5V to 7V for flexible power integration
• Delivers high-speed HCMOS logic levels suitable for direct interfacing with digital circuits

Applications

• Clock generation for microprocessors and microcontrollers requiring precise synchronization
• Timing reference sources for communication interfaces and data transmission systems
• Embedded systems design where low power consumption and small form factor are critical
• Industrial control equipment operating in extended temperature environments

Procurement Notes

Verify that the specific order matches the manufacturer part number 12.95191 to ensure correct frequency and package dimensions. Confirm that the receiving facility can handle surface-mount components without leaded alternatives. Check that the application circuit supports the specified voltage range and current requirements. Ensure storage conditions comply with moisture sensitivity level classifications to prevent damage before reflow soldering.

Selection Notes

Choose this component when a fixed 25 MHz frequency is required with minimal external circuitry. Select this model over tunable variants if frequency agility is unnecessary and cost efficiency is prioritized. Consider the tri-state feature if bus sharing or power management during idle periods is a system requirement. Verify that the 4-SMD footprint fits within the available PCB area constraints.

Part Context

This oscillator belongs to the KXO-V96 series manufactured by Geyer Electronic America, Inc., which specializes in frequency control products. The series includes various frequencies and packages designed for surface-mount technology. These devices are intended to replace discrete crystal and driver combinations, offering a compact solution for timing needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, HCMOS output type, and 4-SMD package dimensions. Verify that any alternative component supports the same -0.5V to 7V supply range and tri-state functionality. Ensure thermal characteristics align with the -40°C to 85°C operating range for equivalent environmental performance.
