The decoding part supports a full audio specification and
can operate at two different disc speeds, from
single-speed (n = 1) to 4 times speed (n = 4). The factor ‘n’
is called the overspeed factor. A simplified data flow
through the decoder part is illustrated in Fig.7.

7.1.2
The SAA7324 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, 2 or 4).
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.
