TB31262F
TOSHIBA Bi- CMOS Integrated Circuit Silicon Monolithic
TB31262F
RF 1chip IC for 900 MHz Cordless Telephone
One package involve three systems about RF, IF, and AF.
Involving LNA, MIX, PA, VCO (TX,RX), PLL, IF-AMP, Detecter,
Compander,and 4 useful audio amplifiers. It is possible to reduce
many external parts. This IC is suitable for ISM 900 MHz
cordless telephone.

3. Data Latch Control
This block has 4 registers assigned by 2 or 3 bits CODE. DATA is read on the time of up edge of CLK. When
STB receivers high signal, DATA in shift register is sent into LATCH to control block which CODE
indicates and the operation starts.
INPUT TIMING FOR SERIAL DATA
When both CLK “H” and DATA “L”, STB “H” leads data active.
