Replacement verdict
Compatible functional replacement candidate
The 5PB1104CMGI8 is a viable functional replacement candidate for the 5PB1102CMGI in applications requiring an additional output channel, provided that the differing output count and package footprint are validated against the target design. Both devices share the same fanout buffer function, supply voltage range, and operating temperature range, but they are not pin-to-pin or footprint compatible, so layout and channel-count requirements must be confirmed before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | 5PB1102CMGI | 5PB1104CMGI8 | Why it matters |
|---|---|---|---|
| Number of Outputs | 2 | 4 | Determines how many clock loads can be driven from a single device; a direct functional difference affecting fan-out capability. |
| Input Type | Differential (LVDS/LVPECL/HCSL/CML compatible) | Differential (LVDS/LVPECL/HCSL/CML compatible) | Defines the signal format the buffer accepts; matching input types ensures drop-in compatibility with the upstream clock source. |
| Output Type | LVCMOS | LVCMOS | Specifies the output signal standard; identical output types allow the same downstream loads to be driven. |
| Supply Voltage | 3.3 V | 3.3 V | Must match the system power rail; identical supply voltage supports direct substitution without power redesign. |
| Maximum Output Frequency | 200 MHz | 200 MHz | Sets the upper limit of clock rates the device can distribute; equal ratings mean equivalent speed capability. |
| Package / Mounting | 16-TSSOP (surface mount) | 16-TSSOP (surface mount) | Footprint and assembly compatibility; identical packages allow the same PCB land pattern to be reused. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental conditions the part supports; matching ranges ensure suitability for the same application environments. |
| Output-to-Output Skew | Typical 50 ps | Typical 50 ps (per output pair) | Affects timing alignment between outputs; with more outputs, skew accumulation across the wider fan-out can impact synchronous timing budgets. |

Frequently asked questions
What are the 5PB1102CMGI and 5PB1104CMGI8 devices?
The 5PB1102CMGI and 5PB1104CMGI8 are Renesas (formerly IDT) 5PB11xx series LVCMOS clock fanout buffers. The 5PB1102CMGI is a 1-to-2 fanout buffer, while the 5PB1104CMGI8 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 between the 5PB1102CMGI and 5PB1104CMGI8?
The primary difference is the number of outputs. The 5PB1102CMGI provides two LVCMOS outputs, whereas the 5PB1104CMGI8 provides four LVCMOS outputs. Both share the same supply voltage range, package type, and general clock distribution function, but the 5PB1104CMGI8 supports more destination loads.
Are the 5PB1102CMGI and 5PB1104CMGI8 pin-compatible?
No. Although both are in a 16-pin QFN package, the 5PB1102CMGI uses fewer output pins than the 5PB1104CMGI8. The additional outputs on the 5PB1104CMGI8 occupy pins that are not driven in the same way on the 5PB1102CMGI. A direct drop-in replacement is not possible without verifying the pinout and PCB layout against the respective datasheets.
What supply voltage range do the 5PB1102CMGI and 5PB1104CMGI8 support?
Both devices operate from a supply voltage range of 1.8 V to 3.3 V, with a nominal 2.5 V or 3.3 V operation commonly used in clock distribution applications. Always confirm the exact recommended operating conditions in the Renesas datasheet for the specific device.
What is the maximum output frequency of the 5PB1102CMGI and 5PB1104CMGI8?
Both the 5PB1102CMGI and 5PB1104CMGI8 are specified for output frequencies up to 200 MHz. This makes them suitable for distributing LVCMOS clocks in applications such as networking, computing, and industrial systems.
Can the 5PB1104CMGI8 be used to replace the 5PB1102CMGI in an existing design?
Not as a direct drop-in replacement. The 5PB1104CMGI8 has four outputs instead of two, so the PCB layout, load conditions, and pin connections must be reviewed. If the design only requires two outputs, the 5PB1102CMGI remains the correct choice. If additional fanout is needed, the 5PB1104CMGI8 may be used after validating pinout, signal integrity, and power dissipation.
What package type do the 5PB1102CMGI and 5PB1104CMGI8 use?
Both devices are offered in a 16-pin QFN (quad flat no-lead) package. The package dimensions and thermal characteristics are consistent within the 5PB11xx family, but the pin assignments differ between the 2-output and 4-output versions.
Are the 5PB1102CMGI and 5PB1104CMGI8 RoHS compliant?
Yes. Both the 5PB1102CMGI and 5PB1104CMGI8 are RoHS-compliant and halogen-free, as stated in the Renesas environmental documentation. Verify the latest compliance status through the official Renesas product pages or authorized distributors such as DigiKey or Mouser.
