Replacement verdict
Compatible functional replacement candidate
The 5PB1104CMG1 is a viable functional replacement candidate for the 5PB1102CMGI, sharing the same 1:4 LVCMOS fanout buffer function, 3.3V supply, and 8-pin package family. Designers must validate the additional output channel, exact package body dimensions, and full operating temperature range before committing to a drop-in substitution.

Frequently asked questions
What are the 5PB1102CMGI and 5PB1104CMG1?
The 5PB1102CMGI and 5PB1104CMG1 are Renesas (formerly IDT) 5PB11xx series clock fanout buffers. The 5PB1102CMGI is a 1-to-2 LVCMOS clock buffer, and the 5PB1104CMG1 is a 1-to-4 LVCMOS clock buffer, both designed for low-skew clock distribution in computing, networking, and industrial applications.
What is the main difference between the 5PB1102CMGI and 5PB1104CMG1?
The primary difference is the number of output channels. The 5PB1102CMGI provides two LVCMOS outputs, while the 5PB1104CMG1 provides four LVCMOS outputs. Both devices share the same 5PB11xx family architecture, input structure, and low-skew design philosophy.
Are the 5PB1102CMGI and 5PB1104CMG1 pin-to-pin compatible?
No. Because the 5PB1102CMGI has two outputs and the 5PB1104CMG1 has four outputs, they have different pin counts and pinouts. The 5PB1102CMGI is typically offered in an 8-pin package, while the 5PB1104CMG1 is typically offered in a 16-pin package. They are not direct drop-in replacements for each other.
What supply voltage do the 5PB1102CMGI and 5PB1104CMG1 operate at?
Both devices operate from a 3.3 V or 2.5 V supply, depending on the specific ordering option and configuration. Designers should confirm the exact VDD range in the respective Renesas datasheet for the targeted part number before finalizing the power design.
What is the output type of the 5PB1102CMGI and 5PB1104CMG1?
Both devices provide LVCMOS-compatible clock outputs. They are intended for fanout of a single reference clock to multiple destinations while maintaining low output-to-output skew, which is critical in synchronous digital systems.
Can the 5PB1104CMG1 be used to replace the 5PB1102CMGI in an existing design?
Not as a direct drop-in replacement. Although both are 5PB11xx LVCMOS clock buffers, the 5PB1104CMG1 has additional outputs and a different package and pinout. A replacement requires PCB layout changes, verification of input and output loading, and confirmation that the additional outputs are either used or properly terminated.
What applications are the 5PB1102CMGI and 5PB1104CMG1 suitable for?
These clock buffers are suitable for applications requiring low-skew clock distribution, such as servers, storage systems, networking equipment, and industrial control boards. The 5PB1102CMGI is used where two clock loads must be driven, while the 5PB1104CMG1 supports designs requiring four clock loads from a single reference.
Do the 5PB1102CMGI and 5PB1104CMG1 support the same input signal types?
Both devices accept a single-ended reference clock input compatible with LVCMOS/LVTTL levels, consistent with the 5PB11xx family. The input structure and threshold levels are defined in the Renesas datasheet, and designers should verify input swing, frequency range, and termination requirements for each specific part number.
