S318025T-27.000-R

Oscillators Overview

The S318025T-27.000-R is a crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a nominal frequency of 27.0000 MHz. It utilizes HCMOS output logic and features a 1.8V supply voltage with an enable/disable control function. The device is housed in a compact 4-SMD, No Lead surface-mount package, specifically sized as 3.2mm x 5.0mm x 1.3mm. It offers a frequency stability of ±25ppm and operates within a temperature range of -40°C to +85°C. Maximum current consumption is specified at 6mA.

Oscillators Feature Summary

• Integrates HCMOS output for standard digital interface compatibility
• Includes hardware enable and disable control functionality
• Provides stable frequency generation with ±25ppm accuracy
• Designed for low-power operation with 1.8V supply requirement

Oscillators Applications

• Microprocessor-based system clocking
• Telecommunications equipment timing
• Data storage and delivery systems
• Computer product synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions of 3.2mm x 5.0mm. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Validate the enable pin logic level compatibility with the controlling microcontroller or GPIO.

Oscillators Selection Notes

Select this component when a precise 27 MHz reference is required for digital logic interfaces. The HCMOS output ensures direct driving capability for most CMOS-compatible inputs without additional buffering. Consider the ±25ppm stability sufficient for general-purpose timing applications rather than high-precision RF synthesis. The 1.8V supply makes it suitable for battery-operated or low-voltage portable devices. Evaluate the thermal performance within the -40°C to +85°C range for the intended operating environment.

Oscillators Part Context

Aker Technology Corp specializes in frequency control solutions, including crystals and oscillators, established since 1990. The S318025T series represents their ultra-miniature CMOS oscillator line, designed for space-constrained applications. This model falls under the standard XO category, distinct from TCXOs or VCXOs which offer tighter stability or tuning capabilities. The product supports automotive, industrial, and consumer electronics markets requiring reliable timing references.

Oscillators Replacement Considerations

Cross-reference with other 27MHz HCMOS SMD oscillators from Aker or competitors ensuring identical 1.8V supply and ±25ppm stability. Verify pinout compatibility for the 4-SMD No Lead package to avoid PCB redesign. Confirm that substitute parts support the same enable/disable control mechanism if utilized in the design.
