12.92146

Overview

The Geyer Electronic America, Inc. model 12.92146 is a standard crystal oscillator (XO) operating at a frequency of 22.1184 MHz. It features a frequency stability of ±100ppm and utilizes a crystal as the base resonator. The device supports HCMOS output levels with a supply voltage range of -0.5V to 7V. It is housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a maximum height of 0.80mm. The component operates within a temperature range of -40°C to 85°C and has a maximum supply current of 11mA.

Feature Summary

• Generates a precise 22.1184 MHz signal using a crystal base resonator for stable timing applications.
• Provides HCMOS logic output levels compatible with standard digital circuit interfaces.
• Operates reliably across an extended industrial temperature range from -40°C to 85°C.

Applications

• Clock generation for microcontrollers and digital processors
• Timing reference for communication interface circuits
• Synchronization sources for embedded system architectures

Procurement Notes

Verify the specific ordering suffix required for your preferred tape-and-reel configuration, such as cut tape or standard reel options available through authorized distributors. Confirm that the ±100ppm frequency stability meets your system's timing tolerance requirements before finalizing the purchase order. Ensure the 4-SMD footprint matches your PCB layout constraints.

Selection Notes

Select this component when a fixed 22.1184 MHz clock source is required with moderate stability needs. The wide supply voltage range allows flexibility in power design, while the compact SMD package suits space-constrained boards. Consider the ±100ppm tolerance against stricter jitter or accuracy demands that might necessitate higher-grade oscillators.

Part Context

This oscillator belongs to the standard XO category manufactured by Geyer Electronic America, Inc., a specialist in frequency control products. It complements their broader portfolio of quartz crystals and ceramic resonators. The 12.92146 part number identifies a specific frequency variant within their surface-mount oscillator lineup designed for general-purpose digital timing.

Replacement Considerations

Direct substitutes must match the 22.1184 MHz frequency, 4-SMD no-lead package dimensions, and HCMOS output type. Verify equivalent supply voltage ranges and temperature ratings to ensure functional compatibility without redesigning the host circuitry.
