1.0 Features

2.0 Description

The FS6217-01 is a CMOS clock generator IC designed

to minimize cost and component count in digital video/

audio systems.

•

27MHz master clock input

•

Generated audio system clocks

SCKO1 : 33.8688MHz (fixed)

SCKO2 : 256 x F_s

The FS6217-01 can generate four system clocks from a

single 27MHz reference frequency.

SCKO3 : 384 x F_s

SCKO4 : 768 x F_s

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).

•

Zero ppm synthesis error on all output clocks

Low cycle-to-cycle and cumulative clock jitter

Multiple sampling frequencies:

Fs = 32, 44.1, 48, 64, 88.2, and 96KHz

(@ 256x, 384x, and 768x F_s)

Fs = 128, 176.4, and 192KHz

(@ 256x and 384x F_s)

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.
