ICS552AR-01 Equivalent & Substitute Parts

Part Overview

The ICS552AR-01 is a Clock Generator and Fanout Distribution IC manufactured by Renesas Electronics Corporation, designed for 200MHz operation in a 20-SSOP surface mount package. This component features a Phase-Locked Loop (PLL) with 1:8 input-to-output ratio, accepting clock or crystal inputs and delivering CMOS outputs across a 3V to 5.5V supply range. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS552AR-01 is determined by strict equivalence across the following critical parameters:

• Maximum frequency operation: 200MHz
• PLL functionality: Required
• Input configuration: Clock or Crystal input capability
• Output standard: CMOS
• Input-to-output ratio: 1:8
• Supply voltage range: 3V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Package type: 20-SSOP (0.154", 3.90mm Width)
• Multiplier capability: Yes
• Differential signaling: No (both input and output)

The substitute part 552AR-01LF meets all specified electrical and mechanical parameters, differing only in packaging format (Tube versus unspecified for the main part) and base product designation. Both components are manufactured by Renesas Electronics Corporation and share identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ICS552AR-01 and 552AR-01LF are classified as obsolete products. Selection between these components should be based on packaging and inventory availability rather than functional differences, as all electrical and mechanical specifications are identical.

The 552AR-01LF is supplied in Tube packaging, which may influence handling, storage, and integration into automated assembly processes. The ICS552AR-01 packaging format is not specified in the provided data.

Both components carry RoHS non-compliant status and are REACH Unaffected. Compliance requirements for your application must be evaluated independently of substitution eligibility.

Current inventory levels are 1120 units for ICS552AR-01 and 769 units for 552AR-01LF, which may influence procurement decisions for long-term system support.

Frequently Asked Questions (FAQ)

Q: Can 552AR-01LF be used as a direct replacement for ICS552AR-01?

A: Yes. All electrical parameters, output specifications, supply voltage range, operating temperature range, and package dimensions are identical. The components differ only in packaging format (Tube for 552AR-01LF).

Q: Are there any pin compatibility concerns?

A: No. Both components use the 20-SSOP (0.154", 3.90mm Width) package with identical pinout and electrical characteristics.

Q: What is the significance of the 1:8 input-to-output ratio?

A: This ratio indicates the clock generator produces eight output signals for each input clock cycle, with frequency multiplication enabled through the integrated PLL.

Q: Does the supply voltage range affect substitution?

A: No. Both parts operate across the identical 3V to 5.5V supply range, ensuring compatibility in systems designed for either component.

Q: Why is product status listed as obsolete?

A: Obsolete status indicates these components are no longer in active production by Renesas Electronics Corporation. Existing inventory from authorized distributors represents the available supply for new designs or system maintenance.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture exposure controls, representing the least restrictive moisture sensitivity classification.
