NB3N2302

NB3N2302 3.3V / 5V 5MHz to 133MHz Frequency Multiplier and Zero Delay Buffer Description The NB3N2302 is a versatile Zero Delay Buffer that operates from 5 MHz to 133 MHz with a 3.3 V or 5 V power supply. It accepts a reference input and drives a B1 and a B2 clock output. The NB3N2302 has an on−chip PLL which locks to the input reference clock presented on the REF_IN pin. The PLL feedback is required to be driven to the FBIN pin and can be obtained by connecting either the OUT1 or OUT2 pin to the FBIN pin. The Function Select inputs control the various multiplier output frequency combinations as shown in Table 1.
