2.0 Description

The FS6217-01 is a C MOS 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 elim inates ext ernal c om ponents and pro vides
the low phase jitter performance needed for high­performance 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, DV D
add-on cards for m ultimedia PCs, digita l HDTV systems ,
and set-top boxes.
