S11805T-12.000-X-R

Oscillators Overview

The S11805T-12.000-X-R is a surface-mount crystal oscillator manufactured by Aker Technology Corp, designed for high-frequency signal generation in compact electronic systems. This specific model operates at a nominal frequency of 12 MHz with a standard output tolerance of ±50 ppm. It utilizes HCMOS logic levels and supports a supply voltage range centered around 1.8V, ensuring compatibility with low-power digital circuits. The device features an enable/disable control function, allowing for power management optimization. Packaged in a 4-pin Ultra Mini-CSMD form factor, it is supplied in tape-and-reel format to facilitate automated assembly processes.

Oscillators Feature Summary

• HCMOS output logic level for direct interface with digital components
• Integrated enable and disable control pin for power efficiency
• Compact 4-pin surface-mount package design
• Standard frequency stability specification

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Communication modules needing precise clock signals
• Microcontroller-based embedded systems
• Industrial control boards with space constraints

Oscillators Procurement Notes

Verify the exact operating temperature range and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the HCMOS output swing is compatible with the input thresholds of downstream logic devices. Check for any specific handling instructions related to the tape-and-reel packaging during storage and reflow soldering processes.

Oscillators Selection Notes

Select this component when a 12 MHz clock source is required in a minimal footprint. Consider the ±50 ppm tolerance if higher precision is needed, alternative models may be necessary. The enable/disable feature makes it suitable for battery-operated devices where power conservation is critical. Ensure the PCB layout accommodates the specific pad configuration of the 4-pin CSMD package to guarantee reliable solder joints.

Oscillators Part Context

This part belongs to the S11805T series of ultra-miniature crystal oscillators from Aker Technology. The series is characterized by its small physical dimensions and low current consumption, targeting applications where board space is limited. Other variants in the series offer different frequencies such as 16 MHz, 20 MHz, 25 MHz, and 30 MHz, maintaining similar electrical characteristics and package styles.

Oscillators Replacement Considerations

Direct replacements must match the 12 MHz frequency, 1.8V supply, HCMOS output, and 4-pin CSMD package. Verify that substitute parts support the same enable/disable functionality and meet the ±50 ppm frequency tolerance. Cross-reference pinouts to ensure compatibility without redesigning the PCB layout.
