Multiplier

Description

MARKING DIAGRAM

The NB3N511 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 200 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 NB3N511 is commonly used in

electronic systems as a cost efficient replacement for crystal

oscillators
