ICS570BIT Equivalent & Substitute Parts

Part Overview

The ICS570BIT is a Fanout Distribution, Spread Spectrum Clock Generator, Zero Delay Buffer IC manufactured by Renesas Electronics Corporation. This 8-SOIC surface mount device operates at frequencies up to 170MHz and is designed for clock distribution applications requiring a 1:2 input-to-output ratio with integrated PLL functionality. The ICS570BIT is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the ICS570BIT is determined by strict equivalence across the following critical parameters:

Functional type: Fanout Distribution, Spread Spectrum Clock Generator, Zero Delay Buffer
Maximum frequency: 170MHz
Input-to-output ratio: 1:2
Supply voltage range: 3.15V ~ 3.45V
Operating temperature range: -40°C ~ 85°C
Package type: 8-SOIC (0.154", 3.90mm Width)
Output signal type: CMOS
PLL presence: Yes
Divider/Multiplier capability: Yes/Yes

The substitute part 570BILFT meets all these electrical and mechanical parameters, differing only in packaging format (Tape & Reel versus individual unit packaging) and product status (Active versus Obsolete).

Engineering Selection Recommendations

The 570BILFT is a direct parametric equivalent to the ICS570BIT across all electrical and mechanical specifications. The primary distinction is product lifecycle status: the ICS570BIT is obsolete while the 570BILFT is active. Additionally, the 570BILFT carries ROHS3 compliance certification, whereas the ICS570BIT is RoHS non-compliant. For new designs or systems requiring long-term component availability, the 570BILFT is the appropriate selection. Both parts share identical functional characteristics, supply voltage requirements, frequency capabilities, and physical package dimensions, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 570BILFT replace the ICS570BIT in existing designs?

A: Yes. The 570BILFT is electrically and mechanically equivalent to the ICS570BIT. Both devices operate at identical supply voltages (3.15V ~ 3.45V), maximum frequency (170MHz), input-to-output ratio (1:2), and are housed in the same 8-SOIC package. Direct substitution is supported without circuit modification.

Q: What is the difference between ICS570BIT and 570BILFT packaging?

A: The ICS570BIT is supplied as individual units, while the 570BILFT is supplied in Tape & Reel (TR) format. Both use the same 8-SOIC (0.154", 3.90mm Width) package. The packaging format difference does not affect electrical performance or physical compatibility on the PCB.

Q: Why is the ICS570BIT listed as obsolete?

A: The ICS570BIT has reached end-of-life status with Renesas Electronics Corporation. The 570BILFT remains in active production and is the recommended part for new applications and ongoing system support.

Q: Does the 570BILFT meet RoHS requirements?

A: Yes. The 570BILFT is ROHS3 compliant. The ICS570BIT is RoHS non-compliant. For applications requiring RoHS compliance, the 570BILFT is the appropriate selection.

Q: Are the PLL and clock distribution characteristics identical between these parts?

A: Yes. Both the ICS570BIT and 570BILFT feature integrated PLL functionality, support clock input with CMOS output, include divider and multiplier capabilities, and maintain a 1:2 input-to-output ratio. Functional performance in clock distribution applications is identical.
