12.90325

Overview

The Geyer Electronic America, Inc. part number 12.90325 is a ceramic surface-mount oscillator (XO) operating at a frequency of 3.6864 MHz. It utilizes an HCMOS output type and supports a supply voltage range of -0.5V to 7V. The device features a maximum supply current of 11mA and operates within a temperature range of -40°C to 85°C. It is housed in a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm.

Feature Summary

• Generates a stable 3.6864 MHz signal using HCMOS logic levels for digital interfacing
• Operates reliably across industrial temperatures from -40°C to 85°C
• Designed for compact surface-mount integration with a small 4-SMD footprint

Applications

• Clock generation for microcontrollers and digital processors
• Timing reference for communication interfaces
• Synchronization circuits in embedded systems

Procurement Notes

Verify the exact frequency specification against the official datasheet before procurement, as distributor listings may contain errors. Confirm that the HCMOS output voltage levels match the receiving circuit's input requirements. Ensure the 4-SMD package dimensions fit the designated PCB land pattern. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a precise 3.6864 MHz timing source is required for HCMOS-compatible logic. Consider the -0.5V to 7V supply range for flexibility in power design. Evaluate the 11mA current consumption against system power budgets. The industrial temperature rating makes it suitable for demanding environments compared to commercial-grade alternatives.
