Frequently asked questions
What are the 5PB1102CMGI8 and 5PB1104CMGI/W?
The 5PB1102CMGI8 and 5PB1104CMGI/W are Renesas (formerly IDT) 5PB11xx series LVCMOS clock fanout buffers. Both are 1-to-2 and 1-to-4 fanout buffers respectively, designed for high-performance clock distribution in applications such as networking, computing, and industrial systems.
What is the difference in fanout capability between the 5PB1102CMGI8 and 5PB1104CMGI/W?
The 5PB1102CMGI8 is a 1-to-2 fanout buffer, providing two outputs from a single input. The 5PB1104CMGI/W is a 1-to-4 fanout buffer, providing four outputs from a single input. The number of outputs is the primary functional difference between these two devices.
Are the 5PB1102CMGI8 and 5PB1104CMGI/W pin-compatible?
No. The 5PB1102CMGI8 and 5PB1104CMGI/W are not pin-compatible. The 5PB1102CMGI8 is offered in an 8-pin package, while the 5PB1104CMGI/W is offered in a 16-pin package. The different pin counts and pin assignments prevent direct PCB footprint compatibility.
What supply voltage do the 5PB1102CMGI8 and 5PB1104CMGI/W operate at?
Both the 5PB1102CMGI8 and 5PB1104CMGI/W operate from a 3.3V nominal supply voltage. They are specified for 3.3V LVCMOS/LVTTL compatible inputs and outputs. Always verify the exact operating voltage range in the latest Renesas datasheet before design.
What is the maximum operating frequency of the 5PB1102CMGI8 and 5PB1104CMGI/W?
Both the 5PB1102CMGI8 and 5PB1104CMGI/W support a maximum input frequency of 200 MHz. This makes them suitable for distributing clock signals in a wide range of digital systems. Confirm the frequency specification in the official Renesas datasheet for the specific revision.
Can the 5PB1102CMGI8 be used as a drop-in replacement for the 5PB1104CMGI/W?
No. The 5PB1102CMGI8 cannot be used as a drop-in replacement for the 5PB1104CMGI/W. They differ in output count (2 vs 4), package size (8-pin vs 16-pin), and PCB footprint. A redesign of the clock distribution network and board layout would be required.
What are the typical applications for the 5PB1102CMGI8 and 5PB1104CMGI/W?
Typical applications include clock distribution in servers, storage systems, networking equipment, and industrial controllers. The 5PB1102CMGI8 is used where two clock outputs are sufficient, while the 5PB1104CMGI/W is used when four outputs are needed from a single clock source.
Do the 5PB1102CMGI8 and 5PB1104CMGI/W have the same output type?
Yes. Both the 5PB1102CMGI8 and 5PB1104CMGI/W provide LVCMOS output levels. They are designed to drive standard LVCMOS/LVTTL clock inputs. The output type is consistent across the 5PB11xx family, but always verify the specific datasheet for output voltage swing and drive strength.
