S33305T-25.000-X-R

Oscillators Overview

The S33305T-25.000-X-R is a surface-mount crystal oscillator manufactured by Aker Technology Corp, operating at a fixed frequency of 25 MHz. It utilizes HCMOS output logic levels and supports a supply voltage range from 1.8V to 3.3V. The device features a frequency stability of ±50 ppm and operates within a temperature range of -40°C to +85°C. Packaged in a compact 4-SMD, No Lead (DFN) footprint measuring 3.2mm x 2.5mm with a height of 1.1mm, it draws a maximum supply current of 7mA. The component is RoHS compliant and lead-free.

Oscillators Feature Summary

• Generates a stable 25 MHz clock signal using HCMOS output interface
• Operates on low voltage supplies ranging from 1.8V to 3.3V
• Provides high frequency stability of ±50 ppm across the industrial temperature range
• Designed for space-constrained applications with a small 4-pin DFN package

Oscillators Applications

• General-purpose digital system clocking
• Microcontroller and microprocessor timing sources
• Embedded communication interfaces requiring precise synchronization
• Consumer electronics and industrial control boards

Oscillators Procurement Notes

Verify that the specific part number suffix matches the required voltage and tolerance specifications. Confirm that the 4-SMD package dimensions align with the PCB footprint design. Ensure compliance with environmental regulations such as RoHS if required by the target market. Cross-reference the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Oscillators Selection Notes

Select this component when a 25 MHz clock source is required with HCMOS compatibility. Consider the 1.8V to 3.3V operating range for power-sensitive designs. The ±50 ppm stability suits standard digital applications where tight jitter constraints are not critical. Evaluate the 3.2mm x 2.5mm footprint against available board space compared to larger packages like the S7 series.

Oscillators Part Context

This model belongs to the S33305T series of surface-mount oscillators from Aker Technology Corp. It shares the same physical footprint and general electrical characteristics with other frequencies in the series, such as the 6MHz and 20MHz variants. The 'T' suffix typically indicates tape-and-reel packaging, while the base S33305 designation refers to the standard 3.2x2.5mm DFN form factor used across multiple frequency options.

Oscillators Replacement Considerations

Direct substitutes include other Aker Technology models within the S33305T series offering different frequencies but identical pinouts and voltages, such as S33305T-20.000-X-R or S33305T-6.000-X-R. Generic replacements must match the 4-SMD DFN package, 25MHz frequency, HCMOS output, and 1.8V-3.3V supply range.
