GEMINAX ADSL Transceiver Chipset
The GEMINAX ADSL transceiver chipset supports
ADSL data transmission according to ITU-T stan-
dards G.dmt and G.lite. With industries lowest board
space requirements and a power consumption of
less than 1 W/ch, the new GEMINAX ADSL
transceiver chipset fulfills all requirements for
highly integrated DSLAM applications.
