FUNCTIONAL DESCRIPTION
7.1
Decoder part
7.1.1
P
RINCIPAL OPERATIONAL MODES OF THE DECODER
The decoding part supports a full audio specification and
can operate at two different disc speeds, from
single-speed (n = 1) to 2 times speed (n = 2). The factor
‘n’ is called the overspeed factor. A simplified data flow
through the decoder part is illustrated in Fig.7.
7.1.2
D
ECODING SPEED AND CRYSTAL FREQUENCY
The SAA7327 is a two speed decoding device, with an
internal Phase-Locked Loop (PLL) clock multiplier.
Depending on the crystal frequency used and the internal
clock settings (selectable via decoder register B), the
playback speeds shown in Table 1 are possible, where ‘n’
is the overspeed factor (1 or 2).
An internal clock multiplier is present, controlled by
SELPLL, and should only be used if a 8.4672 or
16.9344 MHz crystal, ceramic resonator or external clock
is present.

DISC MODE
For Electronic Shock Absorption (ESA) applications, the
SAA7327 can be put into lock-to-disc mode. This allows
Constant Angular Velocity (CAV) disc playback with
