Parameter Comparison

Engineering Selection Recommendations

All three parts—ASE-24.576MHZ-L-R-T, ASE-24.576MHZ-E-T, and ASE-24.576MHZ-L-C-T—are Active status products from Abracon LLC with ROHS3 compliance and MSL 1 rating. Selection between these parts depends on application-specific requirements for frequency stability and operating temperature range.

The ASE-24.576MHZ-L-R-T provides ±25ppm frequency stability across the full -40°C ~ 85°C temperature range, suitable for applications requiring tighter frequency tolerance and extended temperature operation.

The ASE-24.576MHZ-L-C-T offers ±50ppm frequency stability across the full -40°C ~ 85°C temperature range, providing a balance between stability and cost.

The ASE-24.576MHZ-E-T provides ±100ppm frequency stability with a reduced operating temperature range of -20°C ~ 70°C, suitable for applications with less stringent frequency tolerance requirements and standard industrial temperature operation.

Frequently Asked Questions (FAQ)

Q: Can ASE-24.576MHZ-E-T replace ASE-24.576MHZ-L-R-T in all applications?

A: ASE-24.576MHZ-E-T maintains identical electrical and mechanical specifications except for frequency stability (±100ppm vs. ±25ppm) and operating temperature range (-20°C ~ 70°C vs. -40°C ~ 85°C). Substitution is valid only if the application tolerates ±100ppm frequency deviation and operates within -20°C ~ 70°C.

Q: What is the difference between ASE-24.576MHZ-L-C-T and ASE-24.576MHZ-L-R-T?

A: Both parts share identical mechanical packaging and operating temperature range (-40°C ~ 85°C). The primary difference is frequency stability: ASE-24.576MHZ-L-C-T specifies ±50ppm while ASE-24.576MHZ-L-R-T specifies ±25ppm. Selection depends on application frequency tolerance requirements.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 4-SMD, No Lead package with identical dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm) and height (0.047" / 1.20mm), ensuring mechanical and electrical pin compatibility.

Q: Do these oscillators require external components?

A: The provided specifications do not include information regarding external component requirements. Refer to the manufacturer datasheet for circuit implementation details.

Q: What is the significance of Enable/Disable functionality?

A: Enable/Disable functionality allows the oscillator output to be controlled via an external signal, enabling power management in the application circuit. All three parts support this function with identical 10µA maximum supply current in disable mode.
