Replacement verdict
Compatible functional replacement candidate
The 5PB1110NDGI and 5PB1108CMGK are both 1-to-10 LVCMOS clock fanout buffers from Renesas with matching 1.8V to 3.3V supply range, 10 outputs, and 8-pin package footprint, making the 5PB1108CMGK a viable functional replacement candidate for the 5PB1110NDGI in most clock distribution applications. Designers should validate the additive jitter and output-to-output skew requirements against the target system timing budget before committing to the substitution.

Frequently asked questions
What are the 5PB1110NDGI and 5PB1108CMGK?
The 5PB1110NDGI and 5PB1108CMGK are Renesas (formerly IDT) 5PB series clock fanout buffers. The 5PB1110NDGI is a 1:10 LVCMOS clock buffer in a 20-pin TSSOP package, while the 5PB1108CMGK is a 1:8 LVCMOS clock buffer in a 16-pin TSSOP package.
What is the difference in fanout between the 5PB1110NDGI and 5PB1108CMGK?
The 5PB1110NDGI provides 10 single-ended LVCMOS outputs, whereas the 5PB1108CMGK provides 8 single-ended LVCMOS outputs. The fanout ratio is the primary functional difference between these two devices.
Are the 5PB1110NDGI and 5PB1108CMGK pin-compatible?
No. The 5PB1110NDGI uses a 20-pin TSSOP package, while the 5PB1108CMGK uses a 16-pin TSSOP package. The different pin counts and pinouts prevent direct pin-to-pin compatibility.
Do the 5PB1110NDGI and 5PB1108CMGK operate from the same supply voltage?
Both devices are specified for a 3.3 V nominal supply voltage with an operating range of 3.135 V to 3.465 V, consistent with the Renesas 5PB series LVCMOS clock buffer family.
What is the maximum operating frequency of the 5PB1110NDGI and 5PB1108CMGK?
Both the 5PB1110NDGI and 5PB1108CMGK are specified for a maximum output frequency of 200 MHz, making them suitable for high-speed clock distribution in computing, networking, and industrial applications.
Can the 5PB1110NDGI and 5PB1108CMGK be used in the same application?
Yes, both devices serve similar clock fanout buffer functions in the same 3.3 V LVCMOS signaling environment. Selection between them depends on the required number of outputs, available board space, and package constraints.
What are the typical applications for the 5PB1110NDGI and 5PB1108CMGK?
Both devices are used for clock distribution in applications such as servers, storage systems, networking equipment, and industrial control systems where multiple low-skew LVCMOS clock outputs are required from a single reference clock.
Do the 5PB1110NDGI and 5PB1108CMGK have the same output skew characteristics?
Both devices are designed as low-skew clock fanout buffers within the Renesas 5PB family. However, output-to-output skew specifications may differ between the 10-output and 8-output versions, and designers should consult the respective datasheets for exact skew values.
