Replacement verdict
Compatible functional replacement candidate
The 5PB1110NDGI and 5PB1106CMGI8 are both single-channel LVCMOS clock fanout buffers from Renesas with matched 1:10 and 1:6 output configurations, 3.3 V supply, and -40 °C to +85 °C operation. The 5PB1110NDGI offers ten outputs versus six on the 5PB1106CMGI8, so the 5PB1106CMGI8 can serve as a functional substitute only when the reduced fanout is acceptable and the differing package footprint is accommodated on the PCB.

Key electrical and mechanical differences between the two devices
| Parameter | 5PB1110NDGI | 5PB1106CMGI8 | Why it matters |
|---|---|---|---|
| Manufacturer | Renesas Electronics | Renesas Electronics | Same manufacturer ensures consistent quality and support. |
| Function | Clock buffer / fanout buffer | Clock buffer / fanout buffer | Both serve as clock distribution buffers, but channel count and configuration differ. |
| Number of Outputs | 10 | 6 | Output count determines how many clock loads can be driven, affecting system fanout capability. |
| Input Type | Differential (LVPECL/LVDS/HCSL/CML) | Differential (LVPECL/LVDS/HCSL/CML) | Input compatibility must match the upstream clock source for proper signal integrity. |
| Output Type | LVCMOS | LVCMOS | Output logic level must match downstream device requirements. |
| Supply Voltage | 3.3 V | 3.3 V | Supply voltage must be compatible with the system power rail. |
| Package | VFQFPN-32 | VFQFPN-24 | Package footprint and pin count affect PCB layout and board space. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Temperature range must cover the application's environmental conditions. |
| Maximum Output Frequency | 200 MHz | 200 MHz | Frequency capability must support the clock rate required by the system. |
| Additive Jitter | Low (typical < 0.5 ps RMS) | Low (typical < 0.5 ps RMS) | Low jitter preserves clock signal integrity in high-speed applications. |

Frequently asked questions
What are the 5PB1110NDGI and 5PB1106CMGI8?
The 5PB1110NDGI and 5PB1106CMGI8 are Renesas (formerly IDT) 5PB series clock fanout buffers. The 5PB1110NDGI is a 1:10 LVCMOS clock buffer, while the 5PB1106CMGI8 is a 1:6 LVCMOS clock buffer. Both are designed for low-skew clock distribution in applications such as networking, computing, and industrial systems.
What is the difference in fanout between the 5PB1110NDGI and 5PB1106CMGI8?
The 5PB1110NDGI provides 10 single-ended LVCMOS outputs, whereas the 5PB1106CMGI8 provides 6 single-ended LVCMOS outputs. This difference in output count is the primary distinction between the two devices.
Do the 5PB1110NDGI and 5PB1106CMGI8 have the same package type?
No. The 5PB1110NDGI is offered in a 32-pin VFQFN package, while the 5PB1106CMGI8 is offered in a 24-pin VFQFN package. The different pin counts and package sizes affect PCB layout and thermal considerations.
Are the 5PB1110NDGI and 5PB1106CMGI8 pin-compatible?
No. Because the 5PB1110NDGI has 32 pins and the 5PB1106CMGI8 has 24 pins, they are not pin-compatible. A direct drop-in replacement is not possible without PCB redesign.
What supply voltage do the 5PB1110NDGI and 5PB1106CMGI8 require?
Both devices operate from a 3.3 V or 2.5 V supply, depending on the specific ordering option and configuration. Designers should consult the respective datasheets for the exact recommended operating supply voltage range and any required decoupling.
Can the 5PB1110NDGI and 5PB1106CMGI8 be used in the same application?
They can be used in similar applications requiring low-skew LVCMOS clock distribution, but the choice depends on the required number of outputs. The 5PB1110NDGI suits designs needing up to 10 clock loads, while the 5PB1106CMGI8 suits designs needing up to 6 clock loads.
What is the operating temperature range for the 5PB1110NDGI and 5PB1106CMGI8?
Both devices are specified for the industrial temperature range of -40°C to +85°C, making them suitable for industrial and networking equipment. Verify the exact temperature grade in the manufacturer datasheet for the specific part number ordering suffix.
Are the 5PB1110NDGI and 5PB1106CMGI8 RoHS compliant?
Yes. Both the 5PB1110NDGI and 5PB1106CMGI8 are RoHS-compliant and halogen-free, as stated in Renesas environmental documentation. Always confirm compliance status with the latest manufacturer or distributor material declarations.
