Overview
The NB7L14MNG is a differential 1:4 LVPECL fanout buffer produced by onsemi. This component is designed to produce four identical LVPECL output copies of Clock or Data signals, operating up to 7 GHz or 10.7 Gb/s, respectively. It is ideal for various high-speed applications such as SONET, GigE, Fiber Channel, Backplane, and other Clock or Data distribution scenarios. The device features internal 50-ohm termination resistors and supports multiple logic standards including LVPECL, CML, LVDS, LVCMOS, and LVTTL. The NB7L14MNG is part of the GigaComm™ family of high-performance clock products and is functionally compatible with existing 2.5 V and 3.3 V devices.
