ISM97-1251AH-50.000MHZ

Oscillators Overview

The ISM97-1251AH-50.000MHZ is a CMOS standard crystal oscillator manufactured by ILSI, operating at a nominal frequency of 50 MHz. It features a 1.8 V supply voltage and supports an enable/disable function for power management. The device utilizes a 4-SMD, no-lead surface-mount package with dimensions of 3.20 mm x 2.50 mm x 1.20 mm maximum height. It exhibits a frequency stability of ±25 ppm and operates within a temperature range of -40°C to 85°C. Maximum supply current is 20 mA during operation, reducing to 10 µA in the disabled state.

Oscillators Feature Summary

• CMOS output logic levels compatible with standard digital interfaces
• Integrated enable and disable control functionality for power optimization
• Lead-free processing compliance supporting RoHS standards

Oscillators Applications

• General purpose system clock generation
• Embedded digital circuit timing references
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific suffix 'AH' against the manufacturer's official datasheet to confirm pinout configuration and tolerance specifications. Ensure the selected variant matches the required 1.8 V supply voltage and 50 MHz frequency target. Confirm that the 4-SMD no-lead package footprint aligns with the PCB layout design rules. Cross-reference the RoHS status and lead-free processing requirements with project environmental compliance standards before finalizing procurement.

Oscillators Selection Notes

Select this component when a compact surface-mount oscillator with low standby current is required. The 3.2mm x 2.5mm package size suits space-constrained designs. The ±25 ppm frequency stability is adequate for general timing applications but may require tighter tolerances for high-speed serial interfaces. Consider the 1.8 V supply constraint if the system operates at different voltage levels. The enable feature allows for dynamic power management strategies in battery-operated equipment.

Oscillators Part Context

This part belongs to the ILSI ISM97 series of standard crystal oscillators. The series provides various frequency options in a small form factor suitable for modern electronics. The ISM97 line focuses on CMOS outputs and low-power operation. This specific model represents a 50 MHz variant within the broader product family designed for cost-effective timing solutions.

Oscillators Replacement Considerations

Direct substitutes include other ISM97 series variants with matching 50 MHz frequency and 1.8 V supply, such as ISM97-1251AH-50.000MHZ. Verify package compatibility and electrical parameters before substitution.
