NB3N501
3.3V / 5.0V 13 MHz to
160 MHz PLL Clock
Multiplier
Description
The NB3N501 is a clock multiplier that will generate one of nine
selectable output multiples of an input frequency via two 3−level
select inputs (S0, S1). It accepts a standard fundamental mode crystal
or an external reference clock signal. Phase−Locked−Loop (PLL)
design techniques are used to produce a low jitter, TTL level clock
output up to 160 MHz with a 50% duty cycle. An Output Enable (OE)
pin is provided, and when asserted low, the clock output goes into
tri−state (high impedance). The NB3N501 is commonly used in
electronic systems as a cost efficient replacement for crystal
oscillators
