Replacement verdict
Compatible functional replacement candidate
The 5PB1104CMGI/W is a viable functional replacement candidate for the 5PB1102CMGI in applications requiring additional output channels, provided that the higher supply current and added output are acceptable within the target design. Both devices share the same core technology, supply voltage range, and package footprint, but differ in channel count and current consumption, so validation in the end application is recommended.

Key electrical and mechanical differences between the two devices
| Parameter | 5PB1102CMGI | 5PB1104CMGI/W | Why it matters |
|---|---|---|---|
| Number of Outputs | 2 | 4 | Determines how many clock loads can be driven from a single device; a functional substitute must provide at least the same fan-out. |
| Input Type | Differential (LVPECL/LVDS/HCSL/CML compatible) | Differential (LVPECL/LVDS/HCSL/CML compatible) | The input interface must match the upstream clock source for the buffer to accept the signal correctly. |
| Output Type | LVCMOS | LVCMOS | Output logic family must be compatible with the downstream devices being clocked. |
| Supply Voltage | 3.3 V | 3.3 V | The operating supply must match the system rail to avoid level-shifting or damage. |
| Package | 16-TSSOP | 16-TSSOP | Footprint and pinout compatibility are essential for drop-in replacement on an existing PCB. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment for reliable operation. |
| Maximum Output Frequency | 200 MHz | 200 MHz | The buffer must support the clock frequency required by the system without degrading signal integrity. |
| Output-to-Output Skew | Low skew (typical <50 ps) | Low skew (typical <50 ps) | Minimizing skew between outputs is critical for synchronous timing across multiple loads. |

Frequently asked questions
What are the 5PB1102CMGI and 5PB1104CMGI/W devices?
The 5PB1102CMGI and 5PB1104CMGI/W are Renesas (formerly IDT) 5PB11xx series LVCMOS clock fanout buffers. They distribute one input clock to multiple outputs with low additive jitter, targeting networking, computing, and industrial timing applications.
How do the 5PB1102CMGI and 5PB1104CMGI/W differ in output count?
The 5PB1102CMGI provides 2 LVCMOS outputs, while the 5PB1104CMGI/W provides 4 LVCMOS outputs. Both are single-input fanout buffers in the same 5PB11xx family.
Are the 5PB1102CMGI and 5PB1104CMGI/W pin-to-pin compatible?
No. Because the 5PB1104CMGI/W has additional outputs, its pin count and pinout differ from the 5PB1102CMGI. A direct drop-in replacement is not possible without verifying package, pin functions, and PCB layout against the respective datasheets.
What package do the 5PB1102CMGI and 5PB1104CMGI/W use?
Both devices are offered in a 16-pin QFN package, as indicated by the "CMGI" suffix in the ordering code. Designers should confirm the exact package drawing and thermal pad requirements in the Renesas datasheet before layout.
What supply voltage do the 5PB1102CMGI and 5PB1104CMGI/W require?
These 5PB11xx LVCMOS fanout buffers operate from a 3.3 V nominal supply, with the operating range specified in the Renesas datasheet. Always verify the recommended operating conditions and decoupling requirements before design.
Can the 5PB1102CMGI and 5PB1104CMGI/W be used interchangeably in an existing design?
Not directly. The difference in output count changes the pinout and available fanout. Interchangeability requires confirming output count needs, pin mapping, PCB footprint, and signal integrity against both datasheets.
What is the "W" suffix in 5PB1104CMGI/W?
The "W" suffix denotes a specific ordering variant or packing option defined by Renesas for the 5PB1104CMGI. The electrical and functional characteristics remain those of the 5PB1104CMGI; confirm the exact suffix meaning in the Renesas ordering information table.
What applications are the 5PB1102CMGI and 5PB1104CMGI/W suited for?
They are used for clock distribution in applications such as servers, storage, networking equipment, and industrial systems where low additive jitter and multiple LVCMOS clock outputs are required. Selection between them depends on the required number of clock loads.
