\\Cs for Telephone Panasonic Cordless Telephone Speech Network IC Wi Overview — The AN6166NK is a speech network IC for the base set of a cordless telephone. It incorporates a line interface oy 530 $ (speech network) , a compander circuit, and an automat- ig p3? $ ic hold-reset circuit. With a minimal number of external iq Bie components, it can perform all the functions of the base ig Bs 4 set of a cordless telephone. Pie p2 s lid: Bis : i Features Pe Bt 5 «The compressor/expander circuit incorporates pream- isa Teton i 100.25 plifiers to make level and frequency adjustments easier. 474025°33 025 «Incorporates a MUTE function to make the compander circuit independent of the speech network. 4518 «The speech network consumes minimal current, oper- 3-15 62028 ates on low voltage, and supports telephone branching. + Incorporates an MF amplifier, an automatic-pad circuit, SDIP package wit 30 pins (SDIFORO-#-040) and an automatic hold-reset circuit, making the required number of external components minimal. i Block Diagram Vee Em Eo Ecca> Eoer Eour Eker MUTEM/Mr Mi Ta Tro Ln Lr Gu @) a ane O—-)-®)-@)—) Ty ON) a [=] be] |B ) LD>—> n Ct i Prey | LI ie OOO -O-O-O ODO) 0) GNDC Ch Cro Ceca Coer Cin Con Cour Coc Vecr PAD HCc HCo Vic We Crm 932852 0013070 FT Panasonic 779
