Frequently asked questions
What are the 5PB1102CMGI8 and 5PB1102CMGK?
Both are Renesas 5PB1102 series 1-to-2 differential clock fanout buffers. The 5PB1102CMGI8 is supplied in an 8-lead SOIC package and is designated as a tape-and-reel orderable part number, while the 5PB1102CMGK is supplied in an 8-lead VFQFPN package and is also a tape-and-reel orderable part number.
What is the difference between the 5PB1102CMGI8 and 5PB1102CMGK?
The primary difference is the package type. The 5PB1102CMGI8 uses an 8-lead SOIC package, whereas the 5PB1102CMGK uses an 8-lead VFQFPN package. Both devices share the same 1-to-2 differential fanout buffer function and belong to the same 5PB1102 product family.
Are the 5PB1102CMGI8 and 5PB1102CMGK electrically interchangeable?
They are functionally equivalent as 1-to-2 differential clock fanout buffers, but they are not drop-in replacements because the package footprints differ. The 8-lead SOIC and 8-lead VFQFPN packages have different PCB land patterns, thermal characteristics, and mechanical dimensions, so board-level redesign or layout adjustment is required when switching between them.
What supply voltage do the 5PB1102CMGI8 and 5PB1102CMGK operate at?
Both devices operate from a 3.3 V nominal supply, with an operating supply voltage range of 3.135 V to 3.465 V, as specified in the Renesas 5PB1102 datasheet.
What is the operating temperature range for the 5PB1102CMGI8 and 5PB1102CMGK?
Both the 5PB1102CMGI8 and 5PB1102CMGK are specified for the industrial temperature range of -40°C to +85°C, per the Renesas 5PB1102 datasheet.
What output type do the 5PB1102CMGI8 and 5PB1102CMGK provide?
Both devices provide differential outputs. The 5PB1102 is a 1-to-2 differential fanout buffer designed for clock distribution applications, and the output signaling type should be confirmed against the specific datasheet revision for the target design.
Can the 5PB1102CMGI8 and 5PB1102CMGK be used in the same application?
Yes, both can serve the same 1-to-2 differential clock fanout function in an application, provided the PCB layout is designed for the respective package. The 5PB1102CMGI8 requires an 8-lead SOIC footprint, while the 5PB1102CMGK requires an 8-lead VFQFPN footprint.
Which package is smaller, the 5PB1102CMGI8 or the 5PB1102CMGK?
The 5PB1102CMGK in the 8-lead VFQFPN package is smaller than the 5PB1102CMGI8 in the 8-lead SOIC package. The VFQFPN package offers a more compact footprint, which can be advantageous for space-constrained designs.
