Synchronization
SC4810 features a special synchronization function
which is leading-edge triggered with a threshold set to
2.1V. Applications like multi-phase interleaving can be
achieved using the SYNC pin. When the SYNC pin is con-
nected to the RCT pin of the master SC4810, the out-
puts of the two SC4810’s will be out of phase. The fre-
quency of the master SC4810 clock signal should be at
least 30% faster than that of the slave SC4810 for the
guaranteed synchronization. SYNC pin should be
grounded if synchronization is unused. (The patent for
the synchronization scheme is pending).
The synchronous function is illustrated as in Fig. 10.
