ISM97-1251AH-64.000MHZ

Oscillators Overview

The ISM97-1251AH-64.000MHZ is a standard CMOS crystal oscillator manufactured by ILSI, operating at a nominal frequency of 64 MHz with a frequency stability of ±25 ppm. It functions on a single 1.8V supply voltage and features an enable/disable control pin for power management. The device supports a maximum supply current of 20 mA during operation and draws a maximum of 10 µA in the disabled state. Housed in a compact 4-SMD, no-lead surface-mount package measuring 3.20mm x 2.50mm x 1.20mm, it is designed for reliable performance across an industrial temperature range of -40°C to +85°C.

Oscillators Feature Summary

• CMOS output signal generation for digital logic interfacing
• Integrated enable/disable functionality for active power management
• Industrial-grade operational reliability within specified thermal limits

Oscillators Applications

• Embedded system clock sources
• Consumer electronics timing circuits
• Industrial control module synchronization

Oscillators Procurement Notes

Verify that the specific part number matches the required frequency tolerance and voltage specifications for your design. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the selected packaging format aligns with your automated assembly capabilities. Cross-reference the manufacturer's latest datasheet for any updates to mechanical dimensions or electrical characteristics before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 64 MHz reference is required for low-power CMOS applications. The 1.8V supply requirement makes it suitable for modern portable devices. Consider the ±25 ppm stability for general timing needs rather than high-precision communication links. The small SMD footprint aids in space-constrained board layouts. Verify that the enable pin can be effectively utilized to reduce standby power consumption in battery-operated systems.

Oscillators Part Context

This oscillator belongs to the ISM97 series from ILSI, which offers various frequencies in a standardized 3.2x2.5mm package. The series provides consistent electrical characteristics across different frequency options, simplifying inventory management for multi-frequency designs. It serves as a direct replacement for other industry-standard oscillators requiring similar form factors and CMOS outputs.

Oscillators Replacement Considerations

Direct substitutes include other ISM97 series variants with compatible frequencies if system architecture allows. Generic replacements must match the 4-SMD no-lead package dimensions and 1.8V CMOS output levels. Verify that alternative components support the same ±25 ppm stability and industrial temperature range to ensure functional equivalence.
