12.97562

Overview

The Geyer Electronic America, Inc. model 12.97562 is a temperature-compensated crystal oscillator (TCXO) designed for surface-mount applications. It operates at a fundamental frequency of 24 MHz with an HCMOS output type and supports tri-state functionality for output enable control. The device requires a supply voltage ranging from 2.7V to 3.6V, typically centered at 3.3V. It features a compact 4-SMD, no-lead package measuring 3.20mm in length and 2.50mm in width, with a maximum height of 0.80mm. The unit is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates temperature compensation circuitry to maintain frequency stability across varying thermal environments
• Provides standard HCMOS logic levels for direct interfacing with digital systems
• Includes tri-state output capability allowing the signal line to be disabled when not in use

Applications

• Wireless communication modules requiring stable clock sources
• Portable electronic devices with limited power budgets
• Industrial control systems operating in variable temperature conditions

Procurement Notes

Verify that the specific order quantity matches the required packaging format, such as tape and reel or cut tape, as availability may vary by distributor channel. Confirm that the supply voltage requirements align with the system design before finalizing procurement. Ensure that the lead times provided by authorized distributors are accounted for in the production schedule to avoid delays.

Selection Notes

Select this component when a stable 24 MHz reference is needed in a small footprint without external tuning components. The TCXO architecture is preferred over standard crystals when environmental temperature fluctuations could compromise timing accuracy. Ensure the host circuit can accommodate the HCMOS output swing and that the 3.3V supply rail is clean enough to meet phase noise specifications.

Part Context

This oscillator belongs to the family of frequency control products manufactured by Geyer Electronic America, Inc., a specialist in quartz crystals and resonators. The company provides timing solutions for global markets, emphasizing reliability in consumer and industrial electronics. This specific part represents a move toward integrated oscillators that replace discrete crystal circuits.

Replacement Considerations

Direct replacements must match the 24 MHz frequency, 3.3V supply, and 4-SMD package dimensions. Verify that substitute parts offer comparable temperature stability and HCMOS output characteristics. Cross-reference pinouts to ensure compatibility with existing board layouts.
