Key Parameters

Substitute Part Grouping Explanation

Substitution of the M675S02-AAT is determined by strict alignment of the following critical parameters:

• Frequency: 622.08 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Base Resonator: Crystal (exact match required)
• Oscillator Type: VCSO (SAW) (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

The CVS575-622.080 manufactured by Crystek Corporation meets all critical substitution criteria. Both parts share identical frequency, output standard, supply voltage, resonator type, oscillator architecture, package configuration, and mounting methodology. Variations in frequency stability, absolute pull range, operating temperature range, and supply current represent acceptable engineering trade-offs within the scope of component substitution.

Parameter Comparison

Engineering Selection Recommendations

The CVS575-622.080 is the qualified substitute for the obsolete M675S02-AAT. Selection of this substitute is supported by the following engineering factors:

Product Status: The CVS575-622.080 maintains active product status with Crystek Corporation, ensuring ongoing availability and manufacturing support. The M675S02-AAT is classified as obsolete, necessitating substitution for continued system support.

Compliance & Certifications: Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming regulatory equivalence. The CVS575-622.080 additionally carries ROHS3 compliance certification, meeting modern environmental standards.

Functional Equivalence: Both oscillators deliver identical frequency output (622.08 MHz), output standard (LVPECL), supply voltage (3.3V), and package configuration (6-SMD, No Lead). These parameters define the functional interface within the host system.

Physical Compatibility: Identical package dimensions and mounting type ensure direct mechanical substitution without PCB redesign. The CVS575-622.080 exhibits a slightly lower maximum seated height (0.098" versus 0.104"), which presents no compatibility constraint.

Performance Trade-offs: The CVS575-622.080 exhibits a narrower operating temperature range (-20°C to 70°C versus -40°C to 85°C) and reduced absolute pull range (±50ppm versus ±100ppm). These parameters must be evaluated against specific system requirements. The CVS575-622.080 demonstrates lower typical supply current (82mA versus 120mA maximum), providing potential power efficiency benefits.

Frequently Asked Questions (FAQ)

Q: Can the CVS575-622.080 directly replace the M675S02-AAT without PCB modifications?

A: Yes. Both parts share identical package configuration (6-SMD, No Lead), footprint dimensions (0.295" L x 0.200" W), and mounting type (Surface Mount). Direct substitution is mechanically and electrically feasible without PCB redesign.

Q: What are the key differences between these two oscillators?

A: The primary differences are product status (M675S02-AAT is obsolete; CVS575-622.080 is active), operating temperature range (M675S02-AAT: -40°C to 85°C; CVS575-622.080: -20°C to 70°C), frequency stability (M675S02-AAT: ±120ppm; CVS575-622.080: ±150ppm), absolute pull range (M675S02-AAT: ±100ppm; CVS575-622.080: ±50ppm), and supply current (M675S02-AAT: 120mA max; CVS575-622.080: 82mA typical).

Q: Is the CVS575-622.080 suitable for applications requiring the full -40°C to 85°C temperature range?

A: No. The CVS575-622.080 operates within -20°C to 70°C. Applications requiring operation below -20°C or above 70°C must evaluate alternative substitutes or retain the original M675S02-AAT if inventory permits.

Q: Does the narrower absolute pull range of the CVS575-622.080 affect system compatibility?

A: The CVS575-622.080 provides ±50ppm pull range versus ±100ppm for the M675S02-AAT. This reduction must be evaluated against specific frequency tuning requirements. Applications requiring pull ranges exceeding ±50ppm may require alternative components.

Q: What is the functional difference between the M675S02-AAT and CVS575-622.080 regarding enable/disable capability?

A: The CVS575-622.080 includes Enable/Disable function capability. The M675S02-AAT specification does not indicate this function. If the original design does not utilize enable/disable functionality, this difference presents no compatibility constraint.

Q: Are both parts REACH and RoHS compliant?

A: Both parts carry REACH Unaffected status. The CVS575-622.080 is ROHS3 compliant. The M675S02-AAT RoHS status is not specified in available documentation.
