4-channel ADPCM transcoder for

digital cordless telephone base stations

BU8710AKS

This is an ADPCM transcoder which conforms to the G.721 standards listed in the 1988 edition of the CCITT recommen-

dations. Simultaneous processing of four encoder and decoder channels is possible, enabling superb affinity with the

quadruple TDMA which is a standard for PHS (personal handy phone) systems. In turn, this enables voice processing

units for individual base stations in the public telephone network to be configured on single chips.

FApplications

PHS base stations

FFeatures

1) Can be connected to µ-law and A-law PCM codec

through a serial interface. (Both long frames and

short frames can be accommodated.)

6) Aninternalbackgroundnoisegenerationfunctionis

provided, which can be controlled separately for in-

dividual channels. (Applicable only to decoders.)

7) The G.711 (µ-law or A-law) output level can be atte-

nuated freely on individual channels.

2) Various functions can be controlled through a CPU

interface.

3) Aninternalpowersavemodecanbecontrolledsepa-

ratelyforindividualchannels. (Separateencoderand

decoder control are possible.) In addition, external

pin control enables power consumption to be re-

duced for the chip as a whole.

8) An internal 64kbps data through mode is provided,

which can be controlled separately for individual

channels.

9) Internal 32kbps and 64kbps data loop back modes

are provided, which can be controlled separately

for individual channels.

4) An internal muting function can be controlled sepa-

rately forindividualchannels. (Separateencoderand

decoder control are possible.)

10) An internal clock generator circuit is provided.

11) SQFP 80 pin package is used.

5) An internal function silence detection is provided,

which can be controlled separately for individual

channels. (Applicable only to encoders.)
