12.90306

Overview

The Geyer Electronic America, Inc. model 12.90306 is a standard crystal oscillator (XO) featuring HCMOS output signals. It operates within a supply voltage range of 1.8V to 3.6V and supports tri-state output enable functionality. The component utilizes a fundamental mode crystal resonator with a frequency stability of ±50ppm. It is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 0.80mm. Designed for surface-mount installation, the device functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Generates stable HCMOS clock signals using a fundamental mode crystal resonator
• Supports tri-state output control for power management flexibility
• Operates on low voltage supplies ranging from 1.8V to 3.6V
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Embedded system clock generation
• Microcontroller timing sources
• Digital signal processing circuits
• Communication interface modules

Procurement Notes

Verify the specific ordering suffix required by your distributor, as packaging options such as Cut Tape (CT) or Reel may vary. Confirm that the selected variant matches the required voltage and output specifications. Ensure compliance with RoHS status requirements if applicable to your manufacturing process. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a low-voltage HCMOS output is required for digital logic interfacing. The ±50ppm frequency stability is suitable for general-purpose timing applications rather than high-precision synchronization needs. Consider the 4-SMD package dimensions for board space constraints. Verify that the operating temperature range meets the environmental conditions of the target application. Ensure the supply voltage aligns with the 1.8V to 3.6V operational window.
