I sure hope WSTL is still working with TXN. Silent Westell has had no announcements since August but TXN has announced a spectacular ADSL line driver. Smallest footprint and power consumption. I hope this will figure into a WSTL offering, though this DSP is most suitable for central office equipment which WSTL has recently shyed away from. Maybe this is what will be necessary to bring them back into the CO.

Texas Instruments New ADSL Line Driver Establishes Lowest Power
Consumption And Smallest Footprint in the Industry
Device is Industry's First to Use Class G Amplifier Architecture
DALLAS, Oct. 4 /PRNewswire/ -- Building on its system-level expertise and extensive real-world ADSL field trial experience, Texas Instruments (NYSE:TXN - news; TI) today announced a new asymmetrical digital subscriber line (ADSL) line driver that consumes approximately 30 percent less power than previous generations and comes in the industry's smallest footprint. This new device gives designers of central office ADSL line cards and digital subscriber loop access multiplexers (DSLAMs) the capability to develop higher density DSLAMs while reducing their power budgets. See ti.com.
This full-rate ADSL and G.lite capable ADSL line driver, designated the THS6032, is the first in the industry to incorporate a Class G amplifier architecture rather than a Class AB amplifier architecture that most ADSL line drivers use. Unlike Class AB amplifiers which have two power supplies, the Class G architecture uses four power supplies, typically + or - 5 Volts (V) and + or - 15V, to obtain its low power consumption. The THS6032 draws from the low-voltage supply and can reduce power consumption to 1.3 Watts on a full-rate 25-ohm ADSL line by automatically switching to the higher voltage power supply when needed. Due to TI's advanced process technology, the THS6032 keeps total harmonic distortion low even when the driver is switching between power supplies.
''TI's addition of the THS6032 line driver provides ADSL service providers a substantial advantage by enabling a significant reduction in per-line power consumption of central office DSLAMs,'' said Jim Zell, product line manager for Texas Instruments high speed amplifier products. ''Currently available in TI's small outline integrated circuit (SOIC) PowerPAD(TM) package, TI will also offer the device in its Microstar(TM) ball grid array (BGA) package in the first quarter 2000. By leveraging this ultra-small BGA package, the THS6032 is 80 percent smaller than competing devices, allowing designers to reduce the size of ADSL line cards and increase the line density of DSLAMs.''
Low-Impedance Shutdown
The THS6032 is capable of further reducing power consumption by shifting into a low-impedance shutdown mode. Unlike many ADSL line drivers, the low- impedance shutdown mode provides the proper back termination required to receive incoming signals while the device is shutdown. This will allow the reception of incoming communications, including 911 emergency calls, while the THS6032 is in shutdown mode.
Industry's Smallest Footprint
The THS6032 currently comes in TI's exclusive 20-pin SOIC PowerPAD package. The PowerPAD package provides enhanced thermal dissipation characteristics in a small surface-mount package and is compatible with automated assembly procedures.
During the first quarter of 2000, the THS6032 will be available in TI's Microstar BGA PowerPAD package that is one-fifth the size of current ADSL line drivers. Microstar is a chip-scale packaging (CSP) option that involves implanting the device die directly into the printed circuit board, eliminating the space requirements of wire leads.
TI's ADSL Chipset Offers Unparalleled Density for Central Office Applications
The THS6032 is also part of TI's DSP-based TNETD4000C multi-line chipset that supports up to four ADSL lines offering unparalleled density in the central office. The TNETD4000C leverages TI's industry-leading TMS320C6000 DSP core, which delivers the programmability equipment manufacturers need to deploy high-performance, cost-effective products in the rapidly changing, multi-service ADSL market. Other devices in the chipset are the TNETD4100 quad universal digital interface, the TNETD4200 ADSL transceiver, the TNETD4020 codec and the THS6062 line receiver.
TI also has a strong DSL patent portfolio that includes patents which are believed to be essential for meeting the American National Standards Institute (ANSI) T1.413 ADSL standard and International Telecommunications Union (ITU) G.992.2 G.lite and G.992.1 full-rate ADSL standards, and patents that enable the development of low-cost, high-performance DSL products.
Support
ADSL designers will be able to easily analyze the performance of the THS6032. TI offers evaluation modules (EVM) so designers can evaluate the THS6032 without the delays that come from developing a prototype board. TI also supplies full documentation, including data sheets and application notes.
Availability
The THS6032 is scheduled to be available in mid-October from Texas Instruments and its authorized distributors. Suggested resale pricing in quantities of 1,000 is $4.53. The THS6032 is planned to be available in the Microstar BGA package during the first quarter of 2000.
