NB4N1158DTR2G

Overview

The NB4N1158DTR2G is a high-performance serial link replicator manufactured by onsemi, designed for Fibre Channel, Gigabit Ethernet, HDTV, and SATA applications. It operates at data rates up to 1.5 Gb/s with differential LVPECL inputs and outputs. The device features three differential inputs (IN, IN0, IN1) and three differential outputs (OUT, OUT0, OUT1), controlled by multiplexer and output enable pins. Powered by a 3.14 V to 3.47 V supply, it dissipates a maximum of 330 mW. Packaged in a 28-lead TSSOP (DT suffix), it supports an operating temperature range of -40°C to +85°C.

Feature Summary

Serial loop replication and loopback control for Fibre Channel, GbE, HDTV, and SATA links
Compliant with T11 Fibre Channel standards at 1.0625 Gb/s and IEEE 802.3z Gigabit Ethernet at 1.25 Gb/s
Three differential LVPECL inputs and three differential LVPECL outputs with external termination requirements
Multiplexer selection allows routing between specific input sources to designated outputs

Applications

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

Procurement Notes

Verify the DT suffix indicates the Tape and Reel shipping format containing 2500 units per reel. Confirm the component is Pb-Free compliant as specified by the 'G' ordering suffix. Ensure the procurement matches the exact model number NB4N1158DTR2G to guarantee the correct package type and quantity.

Selection Notes

Select this component when designing systems requiring serial link replication up to 1.5 Gb/s. Ensure the design accommodates external DC load/termination resistors (typically 50 Ω to VDD - 2.0 V) for the LVPECL outputs. Verify that the power supply voltage remains within the 3.14 V to 3.47 V range for proper operation.

Part Context

This part belongs to the NB4N1158 series of link replicators from onsemi. The DTR2G designation specifically identifies the Tape and Reel packaging variant, distinguishing it from the rail-packaged NB4N1158DTG. Both variants share identical electrical characteristics and pinouts.
