Full Rate Hardware-Based Controllerless ADSL Chipset Features General Description
Apollo controllerless, full rate ADSL modem solution consisting integrated analog front (I80134), transceiver Aframer (I90135), PCI/Utopia interface chip (I90188) Microsoft NDIS miniport driver. Apollo ADSL Chipset solution designed internal modem cards optimized PCs. Apollo Chipset eliminates expensive microcontroller normally required ADSL modem. leveraging fraction PC's host processor's power, Apollo Chipset able achieve full ADSL rate specified ANSI T1.413 issue ITU-T G.992.1 (G.dmt) much lower cost than competitive ADSL chipsets. Apollo also provides host-based V.90 modem option standard AC'97-link. selection between ADSL V.90 done simply changing configuration software.
