Renesas Electronics 87949AYILF Clock Generator IC Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 87949AYILF is a Clock Generator IC designed for 160MHz operation in a 52-LQFP surface mount package. This component functions as a single-circuit clock generator with multiple input signal compatibility (CML, LVCMOS, LVPECL, LVTTL, SSTL) and LVCMOS output capability. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 87949AYILF is determined by strict alignment across the following critical parameters:

Electrical Specifications:

• Maximum frequency operation at 160MHz
• Input signal compatibility with CML, LVCMOS, LVPECL, LVTTL, and SSTL standards
• LVCMOS output configuration
• Single-circuit architecture with 3:15 input-to-output ratio
• Supply voltage range of 3V to 3.6V
• Operating temperature range of -40°C to 85°C

Mechanical & Packaging Requirements:

• 52-LQFP package format (52-TQFP 10x10mm physical dimensions)
• Surface mount mounting type
• MSL rating of 3 (168 Hours)

Compliance & Regulatory:

• REACH Unaffected status
• ECCN classification EAR99

Direct equivalents must match all specified parameters without deviation. The obsolete status of this component necessitates careful verification of alternative sources and inventory availability.

Engineering Selection Recommendations

The 87949AYILF is classified as an obsolete component. Selection of equivalent parts must prioritize:

Product Status Considerations: Obsolete status indicates discontinued manufacturing and limited availability through standard distribution channels. Component sourcing requires verification through authorized distributors or secondary market suppliers maintaining existing inventory.

Compliance & Regulatory Alignment: All substitute components must maintain REACH Unaffected status and EAR99 ECCN classification to ensure regulatory compliance across manufacturing and distribution jurisdictions.

Packaging & Environmental Requirements: The 52-LQFP package format and MSL 3 rating establish specific handling and storage requirements. Substitute components must meet identical moisture sensitivity specifications to maintain assembly process compatibility and long-term reliability.

Electrical Performance Verification: Direct equivalents must demonstrate identical performance across all specified input/output signal types, frequency operation, and supply voltage parameters. The 3:15 input-to-output ratio and single-circuit configuration are non-negotiable functional requirements.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct equivalent to the 87949AYILF? A: A direct equivalent must match all electrical specifications (160MHz maximum frequency, CML/LVCMOS/LVPECL/LVTTL/SSTL input compatibility, LVCMOS output), mechanical packaging (52-LQFP), supply voltage range (3V–3.6V), operating temperature range (-40°C to 85°C), and regulatory compliance (REACH Unaffected, EAR99 ECCN).

Q: Why is the 87949AYILF classified as obsolete? A: Obsolete classification indicates the manufacturer has discontinued production. This status necessitates sourcing from existing inventory held by distributors or secondary market suppliers.

Q: Can I use a different package type as a substitute? A: No. The 52-LQFP package format is a critical specification. Different package types alter physical dimensions, pin configurations, and assembly compatibility, making them unsuitable as direct substitutes.

Q: What is the significance of the MSL 3 rating? A: MSL 3 (Moisture Sensitivity Level 3) specifies that the component requires controlled storage conditions with a maximum floor life of 168 hours after exposure to ambient conditions. Substitute components must maintain this same MSL rating to ensure assembly process compatibility and component reliability.

Q: Are there alternative manufacturers producing equivalent clock generators? A: Substitution criteria are based strictly on the provided electrical and mechanical parameters. Only components matching all specified parameters from any manufacturer qualify as direct equivalents. Verification of alternative manufacturer availability requires consultation of current component databases and distributor inventory.

Q: How do I verify compatibility of a potential substitute? A: Cross-reference all parameters listed in the Key Parameters table against the substitute component's datasheet. Ensure exact matches for frequency, input/output signal types, supply voltage, temperature range, package format, and regulatory compliance status.
