12.94343

Overview

The Geyer Electronic America, Inc. part number 12.94343 is a 32 MHz crystal oscillator (XO) designed for standard digital applications. It utilizes CMOS and TTL compatible output logic levels to ensure broad interoperability with various microcontrollers and logic circuits. The device operates at a supply voltage of 3.3V and features an enable/disable control pin for power management optimization. It is housed in a compact 4-SMD, No Lead surface-mount package, facilitating automated assembly and space-constrained designs. The unit maintains a frequency stability of 50 ppm and functions reliably within an operating temperature range of -20°C to +70°C.

Feature Summary

• CMOS and TTL compatible output logic for versatile integration
• Integrated enable/disable functionality for power efficiency
• Compact 4-SMD no-lead surface mount form factor

Applications

• General-purpose digital timing circuits
• Microcontroller clock sources
• Consumer electronics requiring stable 32 MHz reference
• Industrial control systems operating in standard temperature ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging variations. Ensure that the required frequency stability and temperature range align with your system specifications before finalizing procurement. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a standard 32 MHz clock source with CMOS/TTL outputs is required in a small surface-mount package. Consider the 50 ppm stability specification relative to your system's jitter requirements. Evaluate the 3.3V supply constraint against your board's power distribution network. The enable pin feature should be utilized if dynamic power saving modes are part of the design strategy.
