ICS650R-11I Clock/Frequency Synthesizer Equivalent & Substitute Parts

Part Overview

The ICS650R-11I is a Clock/Frequency Synthesizer IC manufactured by Renesas Electronics Corporation, designed for 80MHz operation in a 20-SSOP surface mount package. This component generates synchronized clock signals using a Phase-Locked Loop (PLL) architecture with crystal input and CMOS output.

The ICS650R-11I carries an Obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity. Active substitute parts maintain identical electrical and mechanical specifications while offering current manufacturing availability and updated compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS650R-11I is determined by strict equivalence across the following critical parameters:

• Functional Architecture: PLL-based clock synthesis with identical input/output configuration
• Frequency Specification: Maximum 80MHz operation
• Electrical Interface: CMOS output driven by crystal input
• Voltage Requirements: 3V to 3.6V supply compatibility
• Temperature Range: -40°C to 85°C operational envelope
• Package Specification: 20-SSOP form factor with 0.154" width (3.90mm)
• Circuit Count: Single synthesizer circuit

The 650R-11ILF meets all substitution criteria as a direct functional equivalent manufactured by the same supplier with identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 650R-11ILF serves as the direct substitute for the obsolete ICS650R-11I. Both components share identical electrical specifications, package geometry, and functional performance characteristics. The primary distinction lies in product lifecycle status and regulatory compliance.

The ICS650R-11I is classified as Obsolete, indicating discontinued manufacturing and limited procurement availability. The 650R-11ILF maintains Active product status with current manufacturing support and improved compliance posture. The 650R-11ILF achieves ROHS3 compliance, whereas the ICS650R-11I is RoHS non-compliant. Both components maintain equivalent REACH and ECCN classifications.

For new designs or system updates requiring clock synthesis at 80MHz with 3V to 3.6V supply operation, the 650R-11ILF is the appropriate selection. For legacy system maintenance where the ICS650R-11I is currently deployed, the 650R-11ILF provides direct functional replacement without circuit redesign or PCB modification.

Frequently Asked Questions (FAQ)

Q: Can the 650R-11ILF replace the ICS650R-11I in existing designs?

A: Yes. The 650R-11ILF is electrically and mechanically identical to the ICS650R-11I. No circuit modifications, firmware changes, or PCB layout adjustments are required. Pin configuration, signal timing, and voltage requirements are equivalent.

Q: What is the significance of the product status difference?

A: The ICS650R-11I is Obsolete, meaning Renesas has discontinued production. The 650R-11ILF is Active, indicating current manufacturing availability and ongoing supplier support. For procurement planning, the 650R-11ILF ensures long-term component availability.

Q: Are there compliance differences between these parts?

A: The 650R-11ILF is ROHS3 compliant, while the ICS650R-11I is RoHS non-compliant. Both maintain identical REACH and ECCN classifications. If your application requires RoHS compliance, the 650R-11ILF is the appropriate selection.

Q: Do package dimensions differ between these parts?

A: No. Both components use the 20-SSOP package with 0.154" width (3.90mm). PCB footprints, solder pad layouts, and mounting requirements are identical.

Q: What is the input:output ratio specification?

A: Both parts operate with a 1:5 input-to-output frequency ratio. A crystal input frequency is multiplied by 5 to produce the 80MHz maximum output frequency.

Q: Are there any frequency or voltage operating differences?

A: No. Both components support identical maximum frequency (80MHz), supply voltage range (3V to 3.6V), and operating temperature envelope (-40°C to 85°C).
