FUNCTIONAL DESCRIPTION
7.1
Decoder part
7.1.1
P
RINCIPAL OPERATIONAL MODES OF THE DECODER
The decoding part supports a full audio specification at
single-speed (n = 1). A simplified data flow through the
decoder part is illustrated in Fig.7.
7.1.2
D
ECODING SPEED AND CRYSTAL FREQUENCY
The SAA7325 is a single-speed decoding device, with an
internal Phase-Locked Loop (PLL) clock multiplier allowing
a choice of different crystals and oscillators to be used
(see Section 7.2). The range of crystal and oscillator
frequencies possible is controlled via decoder register B
and shown in Table 1. The MSB of decoder register B
must be set to logic 0.
The internal clock multiplier is controlled by SELPLL, and
should only be used if a 8.4672 or 16.9344 MHz crystal,
ceramic resonator or external clock is present.
