ISM95-3251AH-16.000MHZ

Oscillators Overview

The ISM95-3251AH-16.000MHZ is a standard crystal oscillator (XO) manufactured by ILSI, designed for surface-mount applications. It operates at a frequency of 16 MHz with a supply voltage of 3.3V and features CMOS output logic levels. The component supports enable/disable functionality and exhibits a frequency stability of ±25ppm across an operating temperature range of -40°C to +85°C. Maximum supply current is specified at 20mA during operation, while disabled current remains below 10µA. The device is housed in a compact 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a maximum height of 1.20mm.

Oscillators Feature Summary

• CMOS output logic compatible with standard digital interfaces
• Enable/Disable control function for power management
• Lead-free processing compliance for environmental standards

Oscillators Applications

• General purpose clock generation in embedded systems
• Data communication interface timing references

Oscillators Procurement Notes

Verify the specific suffix AH against the official ILSI datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the 3.3V supply rail aligns with the component's voltage specifications. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the package dimensions with the PCB footprint library to prevent assembly errors.

Oscillators Selection Notes

Select this model when a 16 MHz CMOS clock signal is required within a -40°C to +85°C industrial temperature range. The ±25ppm stability suits most general digital applications. Consider the 2.50mm x 2.00mm footprint for space-constrained designs. The enable/disable feature allows for dynamic power control in battery-operated devices.
