Описание продукта
The NB7V585M is a differential 1-to-6 CML clock/data distribution chip featuring a 2:1 Clock/Data input multiplexer with an input select pin. The INx/INxb inputs incorporate internal 50-ohm termination resistors and will accept LVPECL, CML, or LVDS logic levels. The NB7V585M produces six identical output copies of clock or data operating up to 7GHz or 10.7Gb/s, respectively. As such, NB7V585M is ideal for SONET, GigE, Fiber Channel, Backplane and other clock/data distribution applications. The 16mA differential CML output structure provides matching internal 50-ohm source terminations, 400mV output swings when externally terminated with a 50-ohm resistor to VCC and is optimized for low skew and minimal jitter. The NB7V585M is powered with either 1.8V or 2.5V supply and is offered in a low profile 5x5mm 32-pin QFN package.
