12.90329

Overview

The Geyer Electronic America, Inc. model 12.90329 is a surface-mount HCMOS crystal oscillator operating at a fundamental frequency of 32 MHz. It features a frequency stability of ±50 ppm and a load capacitance of 15 pF. The device operates on a single 3.3 V supply with a maximum current consumption of 11 mA. It utilizes a 4-SMD, no-lead package measuring 3.20 mm by 2.50 mm with a maximum height of 0.80 mm. The unit supports an enable/disable function and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Generates a stable 32 MHz clock signal using internal crystal resonance.
• Provides HCMOS logic output levels for digital circuit compatibility.
• Includes an enable/disable control pin for power management.

Applications

• Microcontroller system clock generation
• Digital communication interface timing
• Embedded processor synchronization

Procurement Notes

Verify the specific ordering suffix required for your production volume, such as tape-and-reel or cut-tape options, when placing orders. Confirm that the 3.20mm x 2.50mm footprint matches your PCB layout constraints. Ensure the 3.3V supply voltage aligns with your system design before procurement.

Selection Notes

Select this component when a precise 32 MHz reference is required for HCMOS-compatible digital logic. Consider the ±50 ppm stability requirement against your system's jitter tolerance. Verify that the 3.3V operating voltage and 11 mA current draw fit within your available power budget and thermal limits.

Part Context

This part belongs to the KXO-V94T series of ceramic resonators and oscillators manufactured by Geyer Electronic America, Inc. The series focuses on compact surface-mount solutions for frequency control applications. It serves as a direct replacement for legacy through-hole crystals in modern miniaturized electronic designs requiring standardized digital outputs.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Cross-reference with other 32 MHz HCMOS oscillators in the 3225 package only if electrical parameters match exactly.
