NB7L572: Input Mux - 4:1 Differential, 2.5 V / 3.3 V, Clock / Data Fanout Buffer - 1:2 LVPECL

Description: The NB7L572 is a high performance differential 4:1...
  • The NB7L572 is a high performance differential 4:1 Clock/Data input multiplexer and a 1:2 LVPECL Clock/Data fanout buffer. The INx/INxb inputs include internal 50-ohm termination resistors and will accept differential LVPECL, CML or LVDS logic levels. The NB7L572 incorporates a pair of Select pins that will choose one of four differential inputs and will produce two identical LVPECL output copies of Clock or Data operating up to 7GHz or 10Gb/s, respectively. As such, NB7L572 is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The NB7L572 INx/INxb inputs, outputs and core logic are powered by a 2.5 V +/-5% or 3.3V +/-10% power supply. The two differential LVPECL outputs will swing 750mV when externally terminated with a 50-ohm resistor to VCC - 2V, and are optimized for low skew and minimal jitter. The NB7L572 is offered in a low profile 5mm x5mm 32-pin QFN Pb-free package. Application notes, models, and support documentation are available at www.onsemi.com. The NB7L572 is a member of the GigaComm family of high performance clock products.
