Key electrical and mechanical differences between the two devices
| Parameter | 5PB1102CMGI | 5PB1102CMGK | Why it matters |
|---|---|---|---|
| Manufacturer | Renesas Electronics | Renesas Electronics | Same manufacturer ensures consistent design IP, documentation, and support ecosystem. |
| Function | Clock buffer / fanout buffer | Clock buffer / fanout buffer | Identical function is the primary requirement for functional substitutability. |
| Number of Outputs | 2 | 2 | Output count must match to preserve the clock tree fanout in the target design. |
| Supply Voltage | 1.8 V to 3.3 V | 1.8 V to 3.3 V | Compatible supply range allows drop-in use without power rail redesign. |
| Output Type | LVCMOS | LVCMOS | Matching output logic levels ensure interoperability with downstream receivers. |
| Maximum Frequency | 200 MHz | 200 MHz | Frequency capability must meet or exceed the system clock rate for reliable operation. |
| Package / Case | 8-TSSOP / 8-MSOP | 8-DFN / 8-VFQFN | Different package footprints require PCB layout changes and affect thermal and assembly considerations. |
| Mounting Type | Surface Mount | Surface Mount | Both are surface mount, but the differing package body affects solder pad geometry and reflow profile. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +105°C | Wider temperature range in the GK variant supports harsher environments and higher-margin thermal designs. |
| Packaging / Ordering Suffix | Tube / Tray | Tape & Reel | Different packaging affects automated assembly handling and minimum order quantities. |

Frequently asked questions
What are the 5PB1102CMGI and 5PB1102CMGK?
The 5PB1102CMGI and 5PB1102CMGK are Renesas 5PB1102 series 1-to-2 differential clock fanout buffers with selectable output signaling, intended for low-skew clock distribution in computing, networking, and industrial systems.
What is the difference between the 5PB1102CMGI and 5PB1102CMGK?
The primary difference is the ordering suffix and packing method. The 5PB1102CMGI is supplied in tube packaging, while the 5PB1102CMGK is supplied in tape-and-reel packaging. Both use the same 5PB1102 die and the same 16-pin package type.
Are the 5PB1102CMGI and 5PB1102CMGK electrically and functionally identical?
Yes. Because both part numbers refer to the same 5PB1102 device in the same package and temperature grade, they share the same electrical specifications, pinout, and functional behavior. The difference is limited to the manufacturer’s packaging and shipping format.
Can the 5PB1102CMGI and 5PB1102CMGK be used interchangeably in a design?
Yes, they are interchangeable in the PCB assembly process because they have the same package, pinout, and electrical characteristics. The choice between them is typically based on production handling requirements, such as tube versus tape-and-reel feeding.
What package type do the 5PB1102CMGI and 5PB1102CMGK use?
Both devices are offered in a 16-pin TSSOP package. Designers should confirm the package drawing and land pattern in the official Renesas datasheet before layout.
What is the operating temperature range for the 5PB1102CMGI and 5PB1102CMGK?
Both parts are specified for the industrial temperature range of -40°C to +85°C, as indicated by the “I” suffix in the ordering code.
Do the 5PB1102CMGI and 5PB1102CMGK support the same output signal types?
Yes. Both are 5PB1102 devices and support the same selectable output signaling options defined in the 5PB1102 datasheet. The packaging suffix does not change the output mode configuration.
Which part number should be ordered for automated reel-fed assembly?
The 5PB1102CMGK should be selected for tape-and-reel assembly. The 5PB1102CMGI is the tube-packaged version and is typically used for manual handling, prototyping, or low-volume production.
