ISM97-1251AH-8.000MHZ

Oscillators Overview

The ISM97-1251AH-8.000MHZ is a standard CMOS crystal oscillator manufactured by ILSI, operating at a frequency of 8 MHz. It features a single supply voltage of 1.8V and supports enable/disable functionality with a maximum supply current of 20mA during operation and 10µA in the disabled state. The device utilizes a 4-SMD, no-lead surface-mount package measuring 3.20mm x 2.50mm x 1.20mm. It offers a frequency stability of ±25ppm and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• CMOS output signal generation for digital logic interfacing
• Integrated enable and disable control pin for power management
• Compact surface-mount design suitable for space-constrained PCB layouts

Oscillators Applications

• Embedded system clock sources
• Microcontroller timing references
• Portable electronic devices requiring low-power oscillation

Oscillators Procurement Notes

Verify that the specific part number matches the required 8 MHz frequency and 1.8V supply voltage specifications. Confirm that the 4-SMD no-lead package dimensions align with the target footprint. Ensure compatibility with the intended operating temperature range of -40°C to +85°C. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V CMOS oscillator is required for precise timing applications. Consider the ±25ppm frequency stability requirement against system tolerance needs. Evaluate the physical size constraints to ensure the 3.20mm x 2.50mm package fits the design. Verify that the enable/disable feature provides necessary power savings for battery-operated systems.

Oscillators Part Context

This oscillator belongs to the ISM97 series from ILSI, designed as a compact solution for standard clock generation. The series typically includes various frequencies and voltage options, maintaining consistent package dimensions across variants. It serves as a direct replacement for other small-form-factor XO components in consumer and industrial electronics where space and power efficiency are critical design factors.

Oscillators Replacement Considerations

Direct substitutes may include other 8 MHz, 1.8V CMOS oscillators in a 4-SMD no-lead package from different manufacturers. Verify pinout compatibility and electrical parameters such as current consumption and stability before substitution. Cross-reference with ILSI's broader ISM97 lineup for alternative frequencies or voltages if system requirements change.
