NB4N7132DTG

Overview

The NB4N7132DTG is a high-performance 3.3 V serial link replicator designed for Fibre Channel, Gigabit Ethernet, HDTV, and SATA applications. It supports data rates up to 1.5 Gb/s with LVPECL differential inputs and outputs. The device features three independent input channels (IN, IN0, IN1) and three corresponding output channels (OUT, OUT0, OUT1), allowing flexible signal routing via MUX pins. Operating within a supply voltage range of 3.14 V to 3.47 V, it consumes a maximum power dissipation of 450 mW. Packaged in a 28-lead TSSOP, the component includes internal biasing and output enable controls.

Feature Summary

• Replicates serial links for Fibre Channel, Gigabit Ethernet, HDTV, and SATA at speeds up to 1.5 Gb/s
• Compliant with T11 Fibre Channel standards at 1.0625 Gb/s, IEEE802.3z Gigabit Ethernet at 1.25 Gb/s, and SMPTE-292M at 1.485 Gb/s
• Features three differential LVPECL inputs and three differential LVPECL outputs with selectable routing via MUX pins
• Includes output enable pins (OE0, OE1) to power down buffers and reduce current consumption

Applications

• Fibre Channel loop replication and serial loopback control
• Gigabit Ethernet and HDTV link replication
• Serial ATA (SATA) link replication
• Host Bus Adaptors for routing between internal and external connectors
• Hot-pluggable links between redundant switch fabric cards

Procurement Notes

Verify the ordering suffix DTG indicates a lead-free package in a 28-TSSOP rail shipping format. Confirm that the specific revision matches the July 2011 Rev. 1 datasheet requirements. Ensure compatibility with the specified 3.3 V logic levels and LVPECL interface standards before integration into the design.

Selection Notes

Select this component when designing systems requiring serial link replication for Fibre Channel or Gigabit Ethernet interfaces. Ensure the design accommodates the 3.14 V to 3.47 V operating voltage range and provides adequate thermal management for up to 450 mW power dissipation. Verify that the PCB layout supports the 28-TSSOP package dimensions and differential impedance requirements.

Part Context

The NB4N7132 belongs to onsemi's specialized timing and clock product line, specifically targeting high-speed serial communication protocols. It serves as a critical interconnect component in networking and storage infrastructure, enabling signal distribution and loopback functionality without requiring external components for basic operation.

Replacement Considerations

Publicly confirmed substitute part numbers include the Micrel SY897132L and Texas Instruments SN65LVCP15, which offer similar link replication capabilities for Fibre Channel and Gigabit Ethernet applications.
