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 Ω termination resistors and accept differential LVPECL, CML, or LVDS logic levels. The NB7L572 employs a pair of select pins, one of which is selected from four differential inputs and will generate two identical differential LVPECL output copies of the clock or data signal, operating at speeds up to 7GHz and 10Gb/s respectively. Therefore, the 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% supply. The two differential LVPECL outputs swing 750mV when externally terminated with a 50Ω resistor to VCC - 2V and are optimized for low skew and minimal jitter. The NB7L572 is packaged in a thin 5mm x5mm 32-pin QFN lead-free package. The NB7L572 belongs to the GigaComm family of high-performance clock products.
