NB4N7132DTR2G

Overview

The NB4N7132DTR2G is a high-performance serial link replicator designed for Fibre Channel, Gigabit Ethernet, HDTV, and SATA applications. Operating at data rates up to 1.5 Gb/s, it provides loop replication and loopback control functions. The device accepts LVPECL differential inputs and generates corresponding LVPECL outputs. It features independent output enable controls (OE0, OE1) and multiplexer selection pins (MUX0, MUX1) to route signals between internal and external connectors. Powered by a single 3.3 V supply, the unit operates within a temperature range of -40°C to +85°C and is housed in a 28-lead TSSOP package.

Feature Summary

• Supports data rates up to 1.5 Gb/s compliant with Fibre Channel (T11), Gigabit Ethernet (IEEE802.3z), HDTV (SMPTE-292M), and Serial ATA standards.
• Provides serial loop replication and loopback control with selectable input routing via MUX0 and MUX1 pins.
• Features independent output enable pins (OE0, OE1) that power down output buffers when disabled.
• Requires no external components for basic operation; inputs are internally biased to approximately 1.2 V.

Applications

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

Procurement Notes

Verify the ordering suffix 'R2G' corresponds to the Tape & Reel packaging configuration containing 2500 units per reel. Confirm the component is Pb-Free as indicated by the 'G' suffix. Ensure the procurement documentation matches the specific Datasheet Revision 1 published in July 2011 to align with electrical characteristics and pin descriptions.

Selection Notes

Select this component for designs requiring a single-channel serial link replicator operating at frequencies up to 1.5 Gb/s. The device supports LVPECL, CML, LVDS, and HSTL input levels due to its internal 1.2 V biasing. Ensure the PCB layout accommodates the 28-TSSOP package dimensions (9.60 mm x 6.40 mm) and provides adequate thermal dissipation, as maximum power dissipation is rated at 450 mW.

Part Context

This part belongs to the NB4N7132 series of link replicators manufactured by onsemi. The NB4N7132DTR2G variant specifically denotes the tape and reel packaging option. It serves as a signal distribution and loopback control element in high-speed serial communication architectures, replacing discrete logic solutions with an integrated circuit approach.

Replacement Considerations

Publicly confirmed substitute part numbers include the Micrel SY897132L and Texas Instruments SN65LVCP15. These alternatives also function as link replicators for similar high-speed serial interfaces such as Fibre Channel and Gigabit Ethernet.
