DESCRIPTION

ST70137 is STMicroelectronics UNICORN chipset ADSL DMT transceiver for controllerless ADSL CPE modem.

UNICORNTMallows to develop easily and quickly low cost ADSL CPE modem for PC environment.

UNICORNTMis made of two devices, ST70137 and ST70136 or ST70134 (CPE ADSL Analog Front End). ST70137 provides PCI and USB interface. PCI is used to build ADSL CPE modem bundled in the PC, USB interface is used to build external bus powered ADSL modem.

ST70137 is compliant with ITU 992.1 Annexe A and B, with ITU 992.2 and with ANSI T1.413.

UNICORNTMchipset is delivered with a complete PC software suite for Microsoft Windows 98, Windows 2000 and Windows NT. NDIS5.0 PCI driver and USB driver with ADSL modem control and ATM device driver are provided assuring full ATM support. Configuration and diagnostic tools are also provided.

UNICORNTMchipset and PC software ensure interoperability with the most deployed DSLAM.

■ CLOCK & RESET INTERFACE

■ 1.8V AND 3.3V POWER SUPPLY

■ TTL LOGIC LEVELS COMPATIBLE

(DEPENDING ON PADS)

■ POWER MANAGEMENT

■ LOW POWER CONSUMPTION : 0.4W

■ TQFP 144

ST70137 SOFTWARE FEATURES
