External Clock Mode
The SYNC input allows the MAX9702 to be synchro-
nized to an external clock, or another Maxim Class D
amplifier, creating a fully synchronous system, minimiz-
ing clock intermodulation, and allocating spectral com-
ponents of the switching harmonics to insensitive
frequency bands. Applying a TTL clock signal between
1MHz and 2MHz to SYNC synchronizes the MAX9702.
The period of the SYNC clock can be randomized,
allowing the MAX9702 to be synchronized to another
Maxim Class D amplifier operating in SSM mode.
SYNC_OUT allows several Maxim Class D amplifiers to
be cascaded. The synchronized output minimizes inter-
ference due to clock intermodulation caused by the
switching spread between single devices using
SYNC_OUT. The modulation scheme remains the same
when using SYNC_OUT, and audio reproduction is not
affected (see Figure 4).
