PI6C48533-01LE Equivalent & Substitute Parts

Part Overview

The PI6C48533-01LE is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Diodes Incorporated, designed for 2:4 clock distribution at 800 MHz. This component operates with differential inputs and outputs in LVPECL format, housed in a 20-TSSOP surface mount package. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI6C48533-01LE is determined by the following critical parameters:

• Functional Topology: 2:4 input-to-output ratio with differential signal handling
• Package Compatibility: 20-TSSOP surface mount form factor (0.173", 4.40mm Width)
• Signal Interface: LVPECL output format with multi-format input support (CML, HCSL, LVDS, LVHSTL, LVPECL, SSTL)
• Supply Voltage Range: 3V minimum operating voltage
• Temperature Operating Range: Extended industrial range (-40°C ~ 85°C)
• Regulatory Compliance: ROHS3 compliance

The substitute parts identified are Renesas Electronics Corporation clock buffer ICs (8533AG-01LF, 8533AG-01LFT, 8533AGI-01LFT) that maintain identical package geometry, functional topology, and signal interface specifications. These parts operate at 650 MHz maximum frequency, which is within the operational envelope for applications designed for the 800 MHz PI6C48533-01LE.

Parameter Comparison

Engineering Selection Recommendations

8533AGI-01LFT is the primary substitute for the PI6C48533-01LE. This part maintains the extended industrial operating temperature range (-40°C ~ 85°C) matching the original specification, ensuring compatibility with designs requiring full temperature performance. The 8533AGI-01LFT is in active production status with 4200 units in stock, providing long-term availability and supply chain stability.

8533AG-01LFT serves as an alternative substitute with identical frequency and voltage specifications. This part is available in Cut Tape and Digi-Reel packaging with higher inventory (11100 units). The operating temperature range is limited to 0°C ~ 70°C, restricting use to commercial temperature applications.

8533AG-01LF is available in Tube packaging with 1427 units in stock. Like the 8533AG-01LFT, this variant operates within the 0°C ~ 70°C temperature range and is suitable for commercial-grade applications only.

All three substitutes are ROHS3 compliant and maintain identical package geometry and functional topology. Selection should be based on application temperature requirements and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can the 8533AG-01LF or 8533AG-01LFT be used in applications requiring -40°C ~ 85°C operation?

A: No. The 8533AG-01LF and 8533AG-01LFT are rated for 0°C ~ 70°C operation only. Applications requiring extended industrial temperature range must use the 8533AGI-01LFT.

Q: Is the 650 MHz maximum frequency of the substitute parts compatible with designs using the 800 MHz PI6C48533-01LE?

A: The substitute parts operate at 650 MHz maximum frequency. Compatibility depends on the actual clock frequencies used in the application. If the design operates at or below 650 MHz, substitution is valid. Applications requiring operation above 650 MHz cannot use these substitutes.

Q: Are the package dimensions identical between the PI6C48533-01LE and substitute parts?

A: Yes. All parts use the 20-TSSOP (0.173", 4.40mm Width) surface mount package with identical pin configuration and PCB footprint.

Q: What is the difference between the packaging options for the Renesas substitutes?

A: 8533AG-01LF is supplied in Tube packaging. 8533AG-01LFT and 8533AGI-01LFT are supplied in Cut Tape (CT) and Digi-Reel® packaging. Packaging selection does not affect electrical performance or compatibility.

Q: Do all substitute parts support the same input signal formats as the original PI6C48533-01LE?

A: Yes. All substitute parts accept CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL input formats and output LVPECL signals, maintaining full signal interface compatibility.

Q: Are there supply voltage differences between the original and substitute parts?

A: The PI6C48533-01LE operates at 3V ~ 3.6V. The Renesas substitutes operate at 3.135V ~ 3.465V. The substitute voltage range is narrower but overlaps with the original specification, requiring verification that the application power supply falls within both ranges.
