RTC时钟同步缓冲驱动器延迟芯片

The NB7V33M is a differential divide-by-4 clock divider with asynchronous reset. The differential clock inputs include internal 50 Ω termination resistors and accept LVPECL, CML, and LVDS logic levels. The NB7V33M generates a divide-by-4 output copy of the input clock, running at speeds up to 10GHz with minimal jitter. The reset pin is active on a rising edge. When powered on, the internal flip-flops will go into a random state. Reset allows multiple NB7V33Ms in the system to synchronize. The 16mA differential CML output provides a matched internal 50Ω termination that provides an output swing of 400mV when the external receiver is terminated into 50Ω to VCC. The NB7V33M is a 4-way version of the NB7V32M (2-way) in a thin 3mm x 3mm 16-pin QFN package. The NB7V33M belongs to the GigaComm family of high-performance clock products.
