12.94438

Overview

The Geyer Electronic America, Inc. part number 12.94438 is a 12 MHz crystal oscillator (XO) operating in standard mode. It utilizes CMOS and TTL logic families for signal output compatibility. The device functions at a supply voltage of 3.3V and incorporates a tri-state capability, allowing for an output enable function to control signal transmission.

Feature Summary

• Generates a stable 12 MHz frequency signal using quartz crystal technology.
• Supports both CMOS and TTL logic interface standards for broad digital integration.
• Features a tri-state output configuration with an enable pin for bus management.

Applications

• Digital clock generation in microprocessor systems
• Synchronization circuits requiring precise timing references
• Communication interfaces utilizing standard logic levels

Procurement Notes

Verify the specific datasheet edition for the 12.94438 component to confirm current electrical tolerances and pinout configurations. Ensure that the system design accommodates the 3.3V supply requirement and that the tri-state output enable functionality aligns with the target logic family requirements before finalizing procurement.

Selection Notes

Select this oscillator when a fixed 12 MHz frequency is required with standard CMOS or TTL compatibility. The tri-state feature is essential for applications where multiple devices share a common bus line, allowing the oscillator to be disabled when not actively driving the circuit to prevent signal contention.

Part Context

Geyer Electronic America, Inc. represents GEYER frequency-control products in the U.S., distributing quartz crystals, HCMOS oscillators, and ceramic resonators.
