SC2272 Functions description (Compatible:PT2272)

SC2272 decode signal from Din pin. If the code from SC2262 valid same as

SC2272 set and received two times,the data pins will be “1”or “0” same as

SC2262 data pins and will drive the confirm pin Vt to “1”. The SC2272 code same

as SC2262 means:

1 the address pin state of SC2272 same as SC2262 .

2 the oscillator frequency of SC2272 coordinate SC2262

SC2272 Code Description (Compatible:PT2272)

1 There are 12 A/D BIT and 1 SYNC BIT in one frame
