12.90302

Overview

The Geyer Electronic America, Inc. model 12.90302 is a ceramic surface-mount oscillator operating at 8 MHz with ±50 ppm frequency stability. It utilizes HCMOS output and supports a supply voltage range of 1.8V to 3.3V. The device features tri-state output enable functionality and operates within a temperature range of -40°C to 85°C. Packaged in a compact 4-SMD, no-lead form factor measuring 3.20mm x 2.50mm x 0.80mm, it draws a maximum supply current of 11mA during active operation.

Feature Summary

• Generates stable 8 MHz clock signals using HCMOS logic levels for digital interfacing
• Incorporates tri-state control capability to disable outputs when not required
• Designed for reliable performance across industrial temperature ranges

Applications

• Clock source generation for microprocessors and microcontrollers
• Timing reference for communication interface circuits
• Synchronization components in embedded system designs

Procurement Notes

Verify the specific frequency and voltage requirements against the official datasheet before procurement. Confirm that the 1.8V to 3.3V supply range aligns with the target circuit design. Ensure the 4-SMD package dimensions fit the designated footprint on the printed circuit board. Check for any specific handling instructions regarding electrostatic discharge protection during storage and assembly processes.

Selection Notes

Select this component when an 8 MHz timing signal is required with low power consumption constraints. The HCMOS output ensures compatibility with standard digital logic families. Consider the physical size limitations as the 3.20mm x 2.50mm package is suitable for space-constrained applications. Verify that the ±50 ppm stability meets the system's timing accuracy requirements.
