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.
