NB7L14MNTXG

2.5 V/3.3 V 7 GHz/10 Gbps Differential 1:4 LVPECL Fanout Buffer Multi−Level Inputs with Internal Termination NB7L14 www.onsemi.com Description The NB7L14 is a differential 1:4 LVPECL fanout buffer. The NB7L14 produces four identical LVPECL output copies of Clock or Data operating up to 7 GHz or 10.7 Gb/s, respectively. As such, the NB7L14 is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock or Data distribution applications. The differential inputs incorporate internal 50 W termination resistors that are accessed through the VT Pin. This feature allows the NB7L14 to accept various logic standards, such as LVPECL, CML, LVDS, LVCMOS or LVTTL logic levels. The VREFAC reference output can be used to rebias capacitor−coupled differential or single−ended input signals. The 1:4 fanout design was optimized for low output skew applications. The NB7L14 is a member of the GigaComm™ family of high performance clock products. 1 QFN−16 MN SUFFIX CASE 485G • • Input Data Rate > 10.7 Gb/s Input Clock Frequency > 7 GHz 165 ps Typical Propagation Delay 45 ps Typical Rise and Fall Times
