2.0 Description
The FS6217-01 is a CMOS clock generator IC designed
to minimize cost and component count in digital video/
audio systems.
The FS6217-01 can generate four system clocks from a
single 27MHz reference frequency.
This device eliminates external components and provides
the low phase jitter performance needed for high-
performance digital-to-analog converters (DAC) and
analog-to-digital converters (ADC).
The FS6217-01 is ideal for MPEG-2 applications which
use a 27MHz master clock such as: DVD players, DVD
add-on cards for multimedia PCs, digital HDTV systems,
and set-top boxes.
