ICS9112AG-27 Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The ICS9112AG-27 is a clock fanout buffer (distribution) IC manufactured by Renesas Electronics Corporation, designed for 1:4 clock distribution at frequencies up to 140 MHz. This part operates with a supply voltage range of 3V to 3.6V and is housed in an 8-TSSOP surface mount package. The ICS9112AG-27 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS9112AG-27 is determined by the following critical parameters:

• 1:4 Fanout Ratio: All substitute parts must provide identical 1:4 clock distribution capability
• 8-TSSOP Package: Physical and electrical compatibility requires the same package footprint
• Frequency Capability: Substitute parts must support the maximum frequency requirement of the application (140 MHz minimum)
• Supply Voltage Range: Operating voltage must encompass or exceed the 3V to 3.6V range
• Operating Temperature Range: Must support -40°C to 85°C minimum
• Surface Mount Configuration: All substitutes use surface mount technology

Substitute parts are grouped into two categories based on frequency capability:

Category A - Direct Frequency Match (140 MHz): PI6CV2304LE and PI6CV2304LEX provide identical 140 MHz maximum frequency with matching voltage and temperature specifications.

Category B - Enhanced Frequency Capability: CDCV304TPWREP (200 MHz) and PI6CV304LEX (160 MHz) exceed the original frequency specification, providing higher performance margins while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally compatible with the ICS9112AG-27 based on core electrical and mechanical parameters. Selection should prioritize the following factors:

Product Status: All substitute parts carry Active status, ensuring long-term availability and manufacturing support compared to the obsolete ICS9112AG-27.

Regulatory Compliance: CDCV304TPWREP, PI6CV2304LE, PI6CV2304LEX, and PI6CV304LEX are all ROHS3 compliant, meeting current environmental and regulatory requirements. The original ICS9112AG-27 is RoHS non-compliant.

Frequency Headroom: For applications operating at or near 140 MHz, PI6CV2304LE and PI6CV2304LEX provide exact frequency matching. CDCV304TPWREP and PI6CV304LEX offer additional frequency margin (200 MHz and 160 MHz respectively) for designs requiring performance overhead.

Temperature Range: CDCV304TPWREP extends the upper operating temperature to 105°C, compared to 85°C for all other parts. This is relevant only if the application requires operation above 85°C.

Supply Voltage: CDCV304TPWREP supports a lower minimum supply voltage (2.3V) compared to the 3V minimum of other parts. This provides additional flexibility for low-voltage applications.

Packaging and Availability: All substitutes are available in 8-TSSOP surface mount packages with current inventory levels ranging from 1,567 to 4,520 units.

Frequently Asked Questions (FAQ)

Q: Can I use CDCV304TPWREP as a direct replacement for ICS9112AG-27?

A: Yes. CDCV304TPWREP is electrically and mechanically compatible. It provides the same 1:4 fanout ratio in an identical 8-TSSOP package. The higher 200 MHz frequency specification exceeds the original 140 MHz requirement, and the extended temperature range to 105°C provides additional operational margin.

Q: What is the difference between PI6CV2304LE and PI6CV2304LEX?

A: Both parts are manufactured by Diodes Incorporated with identical electrical specifications (1:4 ratio, 140 MHz, 3V to 3.6V supply, 8-TSSOP package). The primary difference is packaging format: PI6CV2304LE is supplied in Tube packaging, while PI6CV2304LEX is supplied in Cut Tape (CT) & Digi-Reel format.

Q: Why does PI6CV304LEX have a higher frequency rating (160 MHz) than the original part?

A: PI6CV304LEX is a higher-performance variant within the Diodes Incorporated product line. The 160 MHz specification provides additional frequency headroom while maintaining full backward compatibility with applications designed for 140 MHz operation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts (CDCV304TPWREP, PI6CV2304LE, PI6CV2304LEX, and PI6CV304LEX) are ROHS3 compliant. The original ICS9112AG-27 is RoHS non-compliant.

Q: Will the substitute parts fit the same PCB footprint as the ICS9112AG-27?

A: Yes. All substitute parts use the 8-TSSOP (0.173", 4.40mm Width) package, which provides identical footprint compatibility for direct board-level substitution.

Q: Which substitute part should I choose for a new design?

A: For new designs, any of the four active substitute parts are suitable. CDCV304TPWREP is recommended if extended temperature operation (to 105°C) or lower supply voltage (2.3V minimum) is required. PI6CV2304LE or PI6CV2304LEX are recommended for exact frequency matching at 140 MHz. PI6CV304LEX is recommended if additional frequency margin (160 MHz) is beneficial for system performance.
