ICS570BT Equivalent & Substitute Parts

Part Overview

The ICS570BT is a Fanout Distribution, Spread Spectrum Clock Generator, Zero Delay Buffer IC manufactured by Renesas Electronics Corporation. This device operates at a maximum frequency of 170MHz and is housed in an 8-SOIC package. The ICS570BT is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and procurement needs. The part belongs to the ClockBlocks™ series and provides clock distribution functionality with integrated PLL capabilities.

Key Parameters

Substitute Part Grouping Explanation

The 570BLFT qualifies as a direct substitute for the ICS570BT based on the following critical parameters:

• Identical manufacturer (Renesas Electronics Corporation)
• Identical functional classification (Fanout Distribution, Spread Spectrum Clock Generator, Zero Delay Buffer)
• Identical maximum frequency specification (170MHz)
• Identical supply voltage range (3.15V ~ 3.45V)
• Identical operating temperature range (0°C ~ 70°C)
• Identical package type (8-SOIC with 0.154" / 3.90mm width)
• Identical input:output ratio (1:2)
• Identical output type (CMOS)
• Identical PLL functionality

The 570BLFT represents the active production equivalent within the same product family, differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 570BLFT is the appropriate selection for new designs and procurement activities. The ICS570BT is obsolete and no longer in active production. The 570BLFT maintains full electrical and mechanical compatibility while offering the advantage of active product status and ROHS3 compliance. Both parts share identical functional specifications, frequency ratings, voltage requirements, and package geometry, enabling direct substitution at the circuit level. The transition from ICS570BT to 570BLFT does not require design modifications or re-qualification of circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 570BLFT replace the ICS570BT in existing designs?

A: Yes. The 570BLFT is electrically and mechanically identical to the ICS570BT. All functional parameters, frequency specifications, voltage ratings, and package dimensions are equivalent. Direct substitution is possible without circuit redesign.

Q: What is the primary difference between these parts?

A: The ICS570BT is obsolete, while the 570BLFT is an active production part. The 570BLFT also carries ROHS3 compliance, whereas the ICS570BT is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints and mounting requirements are identical.

Q: What is the supply voltage requirement?

A: Both parts require a supply voltage in the range of 3.15V to 3.45V. Operating temperature range is 0°C to 70°C for both devices.

Q: Is the 570BLFT available in different packaging options?

A: The 570BLFT is available in Cut Tape (CT) and Digi-Reel® packaging formats. The ICS570BT packaging format was not specified in the available data.

Q: Are there any compliance differences?

A: The 570BLFT is ROHS3 compliant, while the ICS570BT is RoHS non-compliant. Both parts are REACH Unaffected and carry the same ECCN and HTSUS classifications.
