NB4N7132 Link Replicator for Fibre Channel, Gigabit Ethernet, HDTV and SATA Up to 1.5 Gb/s http://onsemi.com Description The NB4N7132 is a high performance 3.3 V Serial Link Replicator which provides the function of serial loop replication and serial loopback control commonly required in Fibre Channel, GbE, HDTV and SATA applications. Other popular applications include Host Bus Adaptors for routing between internal and external connectors, and hot−pluggable links between redundant switch fabric cards. IN is sent to both OUT0 and OUT1; each output is enabled by OE0 and OE1 when HIGH. OUT0 can select either IN or IN1 via the MUX0 pin. Likewise, OUT1 can select between IN or IN0 via the MUX1 pin. Out can select between IN0 and IN1. In Link Replicator applications, such as the Line Card to Switch Card links, IN is transmitted to both OUT0 and OUT1 which either IN0 or IN1 is selected at OUT. In Host Adapter applications, IN goes to OUT0 (an internal connector) which returns data on IN0. IN0 is looped to OUT1 (an external connector) which returns data on IN1 and then back to the SerDes on OUT. The NB4N7132 is packaged in a 4.7 mm x 9.7 mm TSSOP−28.

Figure 5. NB4N7132 Application Interface Example IN+/IN− Input Functionality OEx Output Enable The differential inputs are internally biased to Y1.2 V. In a typical application, the differential inputs are capacitor−coupled and will swing symmetrically above and below 1.2 V, preserving a 50% duty cycle to the outputs. With this technique, the NB4N7132 will accept any differential input allowing for LVPECL, CML, LVDS, and HSTL input levels. The NB4N7132 incorporates output enable pins, OE0 and OE1, that work by powering down the output buffer and associated driving circuitry. Using this approach results in both differential outputs going HIGH, and a reduction in IDD current of approx. 29 mA for each disabled output pair. When OEx is LOW, outputs are disabled, OUTx+ and OUTx− are set HIGH. OUT+ / OUT− Outputs Power Supply Bypass information The OUT+ and OUT− outputs of the NB4N7132 are designed to drive differential transmission lines with nominally 50 or 75 characteristic impedance. These differential output buffers utilize positive emitter coupled logic (PECL) architecture, but they do not require DC output load resistors, and will operate properly with or without the resistors. A clean power supply will optimize the performance of the device. The NB4N7132 provides separate power supply pins for the digital circuitry (VDD) and LVPECL outputs (VDDPn). Placing a bypass capacitor of 0.01 F to 0.1 F on each VDD pin will help ensure a noise free VDD power supply. The purpose of this design technique is to try and isolate the high switching noise of the digital outputs from the relatively sensitive digital core logic.
