Replacement verdict
Compatible functional replacement candidate
The 5PB1102CMGI8 and 5PB1104CMG1 are both single-output LVCMOS clock fanout buffers from the same 5PB11xx family, sharing identical supply voltage, output type, and operating temperature characteristics. The 5PB1104CMG1 offers a higher maximum output frequency and a wider guaranteed operating temperature range, making it a viable functional replacement candidate for the 5PB1102CMGI8 in most applications, provided the higher frequency capability and thermal margin are acceptable.

Key electrical and mechanical differences between the two devices
| Parameter | 5PB1102CMGI8 | 5PB1104CMG1 | Why it matters |
|---|---|---|---|
| Number of Outputs | 2 | 4 | Determines how many clock loads the buffer can drive; a 2-output device cannot directly replace a 4-output device in multi-load designs. |
| Function | Fanout buffer / clock buffer | Fanout buffer / clock buffer | Both serve the same core function, which is the primary requirement for functional substitutability. |
| Input Type | Differential (LVDS/LVPECL/HCSL/CML compatible) | Differential (LVDS/LVPECL/HCSL/CML compatible) | Matching input compatibility ensures the buffer can accept the same upstream clock source without level shifting. |
| Output Type | LVCMOS | LVCMOS | Identical output signaling allows the same downstream loads to be driven without interface changes. |
| Supply Voltage | 2.5 V / 3.3 V | 2.5 V / 3.3 V | Same supply range means the parts can operate in the same power rail environment. |
| Package | 8-TSSOP / 8-MSOP | 8-TSSOP / 8-MSOP | Identical package and pinout simplify board-level drop-in replacement considerations. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature grades ensure both parts are suitable for the same industrial application environments. |
| Maximum Output Frequency | Up to 200 MHz | Up to 200 MHz | Frequency capability must meet the system clock requirement; both support the same maximum frequency. |

Frequently asked questions
What are the 5PB1102CMGI8 and 5PB1104CMG1?
The 5PB1102CMGI8 and 5PB1104CMG1 are Renesas (formerly IDT) 5PB11xx series LVCMOS clock fanout buffers. The 5PB1102CMGI8 is a 1-to-2 fanout buffer, while the 5PB1104CMG1 is a 1-to-4 fanout buffer. Both operate from a 1.8 V to 3.3 V supply and are offered in a 16-pin QFN package.
What is the difference in output count between the 5PB1102CMGI8 and 5PB1104CMG1?
The 5PB1102CMGI8 provides two LVCMOS outputs, whereas the 5PB1104CMG1 provides four LVCMOS outputs. This is the primary functional difference between the two devices.
Are the 5PB1102CMGI8 and 5PB1104CMG1 pin-compatible?
No. Although both devices are housed in a 16-pin QFN package, the 5PB1102CMGI8 uses fewer output pins than the 5PB1104CMG1. The additional outputs on the 5PB1104CMG1 occupy pins that are not functionally equivalent on the 5PB1102CMGI8. A direct drop-in replacement is not possible without verifying the pinout against the respective Renesas datasheets.
What supply voltage range do the 5PB1102CMGI8 and 5PB1104CMG1 support?
Both devices operate from a supply voltage range of 1.8 V to 3.3 V, as specified in the Renesas 5PB11xx series datasheet. The actual operating voltage must be confirmed against the latest revision of the manufacturer datasheet for the specific part number.
What is the maximum operating frequency of the 5PB1102CMGI8 and 5PB1104CMG1?
Both the 5PB1102CMGI8 and 5PB1104CMG1 are specified for a maximum output frequency of 200 MHz. This parameter is common across the 5PB11xx LVCMOS fanout buffer family and should be verified against the current Renesas datasheet.
Can the 5PB1102CMGI8 be used as a substitute for the 5PB1104CMG1 in an existing design?
No, not directly. The 5PB1104CMG1 provides four outputs while the 5PB1102CMGI8 provides only two. Substitution would require redesigning the clock distribution to account for the missing outputs, and the PCB land pattern and pin functions must be validated against both datasheets. A direct drop-in replacement is not supported.
What package type do the 5PB1102CMGI8 and 5PB1104CMG1 use?
Both devices are offered in a 16-pin QFN (quad flat no-lead) package. The package code "MG" in the part number indicates the QFN package option. Package dimensions and thermal characteristics should be confirmed from the Renesas datasheet for each specific part number.
What is the operating temperature range for the 5PB1102CMGI8 and 5PB1104CMG1?
Both the 5PB1102CMGI8 and 5PB1104CMG1 are specified for the industrial temperature range of -40°C to +85°C. This is indicated by the "I" in the part number suffix. Always verify the temperature grade against the latest Renesas datasheet.
