PI6C48535-11LE Equivalent & Substitute Parts

Part Overview

The PI6C48535-11LE is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Diodes Incorporated, designed for 2:4 clock distribution at 500 MHz. This device features differential input and output capabilities with LVCMOS, LVTTL, and Crystal input support, outputting LVPECL signals. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts maintain the same 20-TSSOP package form factor and core 2:4 multiplexer functionality while offering enhanced specifications or extended availability from active manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI6C48535-11LE is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 20-TSSOP (0.173", 4.40mm Width) surface mount package to ensure PCB layout compatibility without redesign.

Functional Architecture: All substitutes maintain the 2:4 multiplexer configuration with differential output capability (LVPECL output), preserving the core clock distribution function.

Input/Output Signal Standards: The main part accepts LVCMOS, LVTTL, and Crystal inputs with LVPECL output. Substitute parts either match these specifications exactly or provide extended input compatibility (CML, HCSL, LVDS, LVHSTL, LVPECL, SSTL) while maintaining LVPECL output.

Frequency Rating: Substitute parts are grouped by maximum frequency specification. Parts rated at 266 MHz or 650 MHz are functionally compatible with 500 MHz applications when frequency requirements do not exceed the substitute's rating.

Supply Voltage Range: Substitute parts operate within 3.135V ~ 3.465V, which overlaps with the main part's 3V ~ 3.6V range, ensuring power supply compatibility.

Temperature Range: Substitutes are available in two temperature grades: 0°C ~ 70°C (commercial) and -40°C ~ 85°C (industrial). Selection depends on application requirements.

Product Status & Availability: Active manufacturer parts from Renesas Electronics Corporation are preferred over the obsolete Diodes part for long-term supply assurance.

Parameter Comparison

Engineering Selection Recommendations

For High-Frequency Applications (500 MHz or above): The 8533AGI-01LF is the only substitute rated for 650 MHz operation, providing frequency headroom above the original 500 MHz specification. This part is active and available from Renesas Electronics, ensuring long-term supply continuity. Extended input compatibility (CML, HCSL, LVDS, LVHSTL, LVPECL, SSTL) provides flexibility for various clock source types.

For Industrial Temperature Range (-40°C ~ 85°C): The 8535AGI-31LF and 8535AGI-31LFT maintain the full industrial temperature specification of the original part. Both are active products with substantial inventory. The choice between these two depends on packaging requirements: tube packaging (8535AGI-31LF) or cut tape with Digi-Reel option (8535AGI-31LFT).

For Commercial Temperature Range (0°C ~ 70°C): The 8535AG-31LF and 8535AG-31LFT are suitable for applications not requiring extended low-temperature operation. These parts offer the same 266 MHz frequency rating and are available in tube or cut tape packaging.

For Packaging Flexibility: Cut tape and Digi-Reel packaging options (8535AG-31LFT, 8535AGI-31LFT) support automated assembly processes and high-volume production. Tube packaging (8535AG-31LF, 8535AGI-31LF) is suitable for manual assembly or lower-volume applications.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can the 8535AG-31LF or 8535AG-31LFT be used in applications requiring -40°C operation?

A: No. These parts are rated for 0°C ~ 70°C operating temperature only. For applications requiring -40°C minimum temperature, use 8535AGI-31LF or 8535AGI-31LFT, which are rated -40°C ~ 85°C.

Q: Is the 8533AGI-01LF a direct replacement for the PI6C48535-11LE?

A: The 8533AGI-01LF is functionally compatible in the same 20-TSSOP package with 2:4 multiplexer architecture and LVPECL output. However, it operates at 650 MHz (versus 500 MHz) and accepts a broader range of input standards. It is suitable for applications where the higher frequency rating and extended input compatibility are acceptable.

Q: What is the difference between tube and cut tape packaging?

A: Tube packaging (8535AG-31LF, 8535AGI-31LF) is used for manual assembly or lower-volume production. Cut tape with Digi-Reel packaging (8535AG-31LFT, 8535AGI-31LFT) is designed for automated pick-and-place assembly equipment and high-volume manufacturing.

Q: Are all substitute parts compatible with the original 3V ~ 3.6V supply voltage?

A: Substitute parts operate within 3.135V ~ 3.465V, which overlaps the original 3V ~ 3.6V range. The narrower voltage window of substitutes requires verification that your power supply design operates within 3.135V ~ 3.465V to ensure full compatibility.

Q: Why do the 8535 series parts have lower frequency ratings (266 MHz) compared to the original 500 MHz?

A: The 8535 series is a different product line optimized for lower-frequency clock distribution applications. The 8533AGI-01LF is the frequency-equivalent substitute at 650 MHz. Selection depends on your actual frequency requirements: if your application operates below 266 MHz, the 8535 series is suitable; if 500 MHz or higher is required, use the 8533AGI-01LF.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting the same environmental standards as the original PI6C48535-11LE.
