NB4N507A

3.3V/5V, 50 MHz to 200 MHz

PECL Clock Synthesizer

Description

The NB4N507A is a precision clock synthesizer which generates a

very low jitter differential PECL output clock. It produces a clock

output based on an integer multiple of an input reference frequency.

The NB4N507A accepts a standard fundamental mode crystal,

using Phase−Locked−Loop (PLL) techniques, will produce output

clocks up to 200 MHz. In addition, the PLL circuitry will produce a

50% duty cycle square−wave clock output.

The NB4N507A can be programmed to generate a selection of input

reference frequency multiples. An exact 155.52 MHz output clock can

be generated from a 19.44 MHz crystal and the x8 multiplier selection.

The NB4N507A is intended for low output jitter clock generation.
