Replacement verdict
Compatible functional replacement candidate
The 5PB1110NDGI and 5PB1106CMGK8 are both single-output LVCMOS clock fanout buffers from the same 5PB11xx family, sharing a 1.8V to 3.3V supply range and similar additive jitter performance. The 5PB1110NDGI offers a higher maximum output frequency and a wider operating temperature range, while the 5PB1106CMGK8 provides a lower maximum frequency and a narrower temperature range. Both devices are functionally comparable for clock distribution applications, but the 5PB1110NDGI is the more capable option where higher frequency and extended temperature operation are required.

Key electrical and mechanical differences between the two devices
| Parameter | 5PB1110NDGI | 5PB1106CMGK8 | 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 | Determines how many clock loads can be driven; affects board-level 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 thermal performance. |
| Operating Temperature | -40°C to +85°C | -40°C to +85°C | Temperature range must cover the application's environmental conditions. |

Frequently asked questions
What are the 5PB1110NDGI and 5PB1106CMGK8?
The 5PB1110NDGI and 5PB1106CMGK8 are Renesas (formerly IDT) 5PB series clock fanout buffers. The 5PB1110NDGI is a 1-to-10 LVCMOS clock buffer in a 20-pin QSOP package, while the 5PB1106CMGK8 is a 1-to-6 LVCMOS clock buffer in a 16-pin VFQFN package.
What is the difference in fanout between the 5PB1110NDGI and 5PB1106CMGK8?
The 5PB1110NDGI provides 10 single-ended LVCMOS outputs, whereas the 5PB1106CMGK8 provides 6 single-ended LVCMOS outputs. The number of outputs is the primary functional difference between the two devices.
Do the 5PB1110NDGI and 5PB1106CMGK8 have the same package type?
No. The 5PB1110NDGI is supplied in a 20-pin QSOP package, and the 5PB1106CMGK8 is supplied in a 16-pin VFQFN package. The different package footprints and pin counts prevent a direct drop-in replacement without PCB redesign.
What supply voltage do the 5PB1110NDGI and 5PB1106CMGK8 operate at?
Both devices operate from a 3.3 V nominal supply, with an operating supply voltage range of 3.135 V to 3.465 V, as specified in the Renesas 5PB11xx datasheet.
What is the maximum operating frequency of the 5PB1110NDGI and 5PB1106CMGK8?
Both the 5PB1110NDGI and 5PB1106CMGK8 support a maximum output frequency of 200 MHz, per the Renesas 5PB11xx datasheet.
Can the 5PB1110NDGI and 5PB1106CMGK8 be used interchangeably in an existing design?
No. Although both are 3.3 V LVCMOS clock fanout buffers from the same 5PB11xx family, they differ in output count (10 vs 6) and package (20-pin QSOP vs 16-pin VFQFN). A direct substitution requires verifying pinout, footprint, output loading, and signal integrity against the target design.
What is the operating temperature range for the 5PB1110NDGI and 5PB1106CMGK8?
Both the 5PB1110NDGI and 5PB1106CMGK8 are specified for the industrial temperature range of -40 °C to +85 °C, as stated in the Renesas 5PB11xx datasheet.
Are the 5PB1110NDGI and 5PB1106CMGK8 RoHS compliant?
Yes. Both the 5PB1110NDGI and 5PB1106CMGK8 are RoHS-compliant devices, as indicated by Renesas in the 5PB11xx datasheet and product ordering information.
