Description
The NB3N501 is a clock multiplier that will generate one of nine selectable output multiples of an input frequency via two 3âlevel select inputs (S0, S1). It accepts a standard fundamental mode crystal or an external reference clock signal. PhaseâLockedâLoop (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 triâstate (high impedance). The NB3N501 is commonly used in electronic systems as a cost efficient replacement for crystal oscillators
