There are 4 programmable hysteresis input buffer, shown in Figure 6-17, are determined by Low/
High nibbles of PHxx. The hysteresis control formulas are list below.
Alert tone hysteresis
HAT=13mv + 3mv*X
DTMF hysteresis
HDTMF=6mv + 3mv*X
FSK hysteresis
HFSK=13mv + 3mv*X
FSK detector hysteresis
HFSKD=13mv + 3mv*X
Application Circuit
The analog interface circuit of W925E/C625 shown in Figure 6-26 is a typical CPE system. The
gain control op-amp is set to unit gain to allow the electrical characteristics to be met in this
application circuit.
