5PB1110NDG28

Overview

The Renesas Electronics 5PB1110NDG28 is a high-performance clock buffer belonging to the 5PB1110 series. It functions as a 1:10 fanout buffer with LVCMOS input and output types, designed for distributing clock signals in digital systems. The device supports a maximum operating frequency of 200 MHz and features a maximum propagation delay of 2.5 ns. It operates within a supply voltage range of 1.71 V to 3.465 V and is rated for an industrial temperature range from -40°C to +85°C. The component is housed in a 20-VFQFPN package.

Feature Summary

• 1:10 Fanout Configuration: Distributes a single LVCMOS input signal to ten LVCMOS outputs.
• High Frequency Operation: Supports clock frequencies up to 200 MHz with low propagation delay.
• Wide Voltage Range: Operates on a single supply voltage between 1.71 V and 3.465 V.
• Industrial Temperature Rating: Guaranteed performance across a temperature range of -40°C to +85°C.

Applications

• Clock distribution networks in computing and data communications equipment.
• Signal buffering in networking infrastructure requiring multiple synchronized clock domains.
• Industrial control systems utilizing LVCMOS logic families.

Procurement Notes

Verify the specific suffix 'G28' against official Renesas documentation to confirm tape-and-reel packaging specifications, as standard listings often reference 'NDGI' (tray) or 'PGGI' (TSSOP). Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to ordering to ensure compatibility with surface-mount assembly processes.

Selection Notes

Select this component when a 1:10 LVCMOS fanout ratio is required for frequencies up to 200 MHz. Ensure the design accommodates the 1.71 V to 3.465 V supply range. Compare pin-out dimensions of the 20-VFQFPN package against PCB layout constraints. Consider the 5PB1110NDGI if tray packaging is preferred over the specific reel configuration implied by the suffix.

Part Context

The 5PB1110NDG28 is part of the Renesas 5PB11xx series of clock buffers. This family includes variants with different output counts (e.g., 5PB1104 for 1:4, 5PB1116 for 1:16) and package options. The NDG28 designation specifically identifies the 1:10 buffer variant in the VFQFPN-20 package format.

Replacement Considerations

The 5PB1110NDGI is a parameter-equivalent alternative available in a tray package. For TSSOP packaging requirements, the 5PB1110PGGI serves as a compatible substitute within the same electrical specification envelope.
