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.
