LFOCXO063816BULK

Overview

The LFOCXO063816BULK is a high-performance Oven-Controlled Crystal Oscillator (OCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 12.8 MHz with an initial frequency stability of 20 ppb and aging rates between 3 ppb to 8 ppb. The device utilizes HCMOS output format and requires a single 3.3 V supply voltage. Designed for surface-mount technology, it functions within an extended industrial temperature range from -40°C to +85°C. The component features a compact SMD/SMT termination style suitable for automated assembly processes.

Feature Summary

• Delivers ultra-high frequency stability with 20 ppb initial tolerance
• Features low aging rate ranging from 3 ppb to 8 ppb
• Operates on a standard 3.3 V power supply
• Supports wide industrial temperature operation from -40°C to +85°C

Applications

• Precision timing systems requiring minimal drift
• Telecommunications infrastructure equipment
• Test and measurement instrumentation
• Navigation and positioning systems

Procurement Notes

Verify the specific ordering suffix and packaging configuration against official IQD documentation before procurement. Confirm that the required frequency stability and aging specifications align with system requirements. Ensure compatibility with the 3.3 V supply voltage and HCMOS interface levels. Check for any RoHS compliance details or environmental restrictions relevant to the target market. Validate the surface-mount footprint dimensions for PCB layout accuracy.

Selection Notes

Select this OCXO when superior long-term stability and low phase noise are critical compared to standard TCXOs or SPXOs. The 12.8 MHz frequency is commonly used in digital signal processing and telecommunications applications. Consider the thermal management requirements inherent to oven-controlled designs despite the low power consumption. Evaluate the trade-off between the high performance and the physical size constraints of the SMD package.

Part Context

This component belongs to the LFOCXO series of Oven-Controlled Crystal Oscillators from IQD Frequency Products. The series is designed for applications demanding exceptional frequency accuracy over time and temperature variations. IQD provides these oscillators as part of their comprehensive portfolio of frequency control solutions, catering to industries where signal integrity is paramount.

Replacement Considerations

The product status is listed as discontinued. Engineers must identify alternative OCXOs with matching 12.8 MHz frequency, 3.3 V operation, and similar stability metrics. Verify pinout compatibility and mechanical footprint dimensions to ensure seamless integration into existing hardware designs without significant redesign efforts.
