Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 564BAJC002091ABG is determined by strict alignment across the following critical parameters:

• Output Type: LVDS (Low-Voltage Differential Signaling)
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W x 0.052" H (7.00mm x 5.00mm x 1.33mm)
• Frequency Stability: ±20ppm
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Support: Compatibility with 100MHz, 125MHz, and/or 156.25MHz
• Supply Voltage Compatibility: Support for 1.8V, 2.5V, and/or 3.3V operation
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute part must maintain electrical and mechanical compatibility across all these parameters. Supply voltage range flexibility and maximum current consumption are secondary considerations, provided the primary parameters remain aligned.

Engineering Selection Recommendations

The 564BAJC002091ACG is the manufacturer-recommended substitute for the 564BAJC002091ABG. The substitute part maintains full electrical and mechanical compatibility while offering the following advantages:

• Active Product Status: The substitute is designated as Active, ensuring long-term availability and continued manufacturer support, whereas the main part is marked Not For New Designs.
• Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and handling requirements.
• Improved Current Efficiency: The substitute operates at a maximum supply current of 130mA compared to 157mA in the main part, representing a 17% reduction in power consumption.
• Extended Frequency Support: The substitute adds 200MHz as an available output frequency option, providing additional flexibility for future design iterations.
• Identical Physical Footprint: Both parts share identical package dimensions (7.00mm x 5.00mm x 1.33mm), enabling direct PCB layout compatibility without redesign.

For new designs and ongoing production requiring LVDS XO oscillators in the Si564 series, the 564BAJC002091ACG is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 564BAJC002091ACG be used as a direct replacement for the 564BAJC002091ABG in existing designs?

A: Yes. Both parts share identical LVDS output type, 8-SMD No Lead package, physical dimensions (7.00mm x 5.00mm x 1.33mm), frequency stability (±20ppm), operating temperature range (-40°C ~ 85°C), and support for 1.8V, 2.5V, and 3.3V supply voltages. The substitute requires no PCB layout modifications or circuit redesign.

Q: What is the difference in supply voltage specification between the two parts?

A: The main part specifies discrete voltage levels (1.8V, 2.5V, 3.3V), while the substitute specifies a continuous range (1.8V ~ 3.3V). Both support operation at 1.8V, 2.5V, and 3.3V. The range notation in the substitute indicates broader voltage tolerance across the specified band.

Q: Does the lower maximum current consumption of the substitute part affect performance?

A: No. The substitute's 130mA maximum current specification is lower than the main part's 157mA, indicating improved power efficiency. This reduction does not compromise functional performance and may reduce thermal load in the application circuit.

Q: Are there any frequency compatibility limitations when substituting?

A: The substitute supports all frequencies of the main part (100MHz, 125MHz, 156.25MHz) plus an additional 200MHz option. If your design uses 100MHz, 125MHz, or 156.25MHz, the substitute is fully compatible. The 200MHz option is available for applications requiring higher frequency operation.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates the main part is in end-of-life phase and is not recommended for new product development. The manufacturer-recommended substitute (564BAJC002091ACG) carries Active status, ensuring continued production, technical support, and long-term component availability.

Q: Are both parts RoHS compliant?

A: The main part is explicitly ROHS3 compliant. The substitute's RoHS status is not specified in the provided data. Verify RoHS compliance requirements with the manufacturer or component distributor before final selection for applications with specific regulatory requirements.
