 BD870 |
Legerity's BatteryDirect Family of line drivers is truly an industry first. With proprietary high voltage, high bandwidth process technology, we developed a product that operates directly from the -48V telecom battery making our BD870 Series the most cost effective and easy-to-use parts for today's xDSL applications. |
| VE580 |
Legerity's VoiceEdge™ VE580 Series is comprised of our popular, general purpose, low cost quad and octal codecs that provide a simple analog interface to a variety of ringing and non-ringing SLIC devices. |
| VE750 |
The VoiceEdge™ VE750 Series of Line Card Access Switches (LCAS) is comprised of monolithic solid-state switches designed to provide both power ringing and test access on the analog line. |
| VE770 |
Legerity's VoiceEdge™ VE770 Series are high-performance, highly programmable, integrated chip sets that perform all the functions necessary to create a 2-wire, twisted pair telephone interface from any broadband digital source. |
| VE790 |
Legerity's VoiceEdge™ VE790 Series is a high-performance, highly programmable integrated voice chip set that performs all the functions necessary to create a 2-wire, twisted-pair telephone interface from any broadband digital source. The VE790 Series includes 2, 4, and 8CH programmable codecs along with short, medium and long loop length SLIC devices that together operate with minimal external components and include software to provide a complete system solution. Programmability and integrated line testing, when used with the optional Le79112, make the VE790 Series most flexible chip set available. |

Legerity's VoiceEdge™ Ve880 VoicePort™ series is the first industry offering which implements a single-channel or dual-channel telephone line interface in a single device by providing all the necessary voice interface functions from the high voltage subscriber line to the µP/DSP digital interface. VoicePort devices are feature-rich by offering the highest levels of integration by combining SLIC and codec functionality. The new VoicePort Series provides a high density single chip solution, worldwide compatibility and the lowest system costs for new VoIP designs. Designers benefit from the design flexibility, high performance, low power, high efficiency, small footprint, and a low cost system BOM of the VoicePort solutions. Legerity offers 1 FXS, 2 FXS, and 1.5 FXS as well as 1 FXO VoicePort solutions today.
Software
Legerity's VeriVoice™ Test Suite software provides line testing for select Ve880 devices. |
| VE890 |
Legerity's VoiceEdge™ VE890 product family series consists of highly integrated chipsets that are optimized for low-cost residential VoIP gateways such as voice enabled DSL modems, set-top boxes, and analog terminal adapters.
Coupled with Legerity's VoicePath™ API-II (VP API-II), designers are enabled to offer a single hardware design that is software programmable for worldwide markets. The VP API-II 'C' code is used to abstract Legerity devices from application code while providing functions for controlling, supervising, and testing a set of subscriber lines.
For the FXO channel, the VE8921 and VE8911 chipsets utilize patented low value PCB capacitors, resulting in best in class DAA performance in both common mode and RF immunity.
The following VE890 chipset configurations are presently available:
|
| VE950 |
The VoiceEdge™ VE950 Series offers high performance, voice over broadband SLIC devices with universal differential ringing and codec interfaces optimized for short-loop, power-sensitive applications. The VE950 products are designed to interface to gateway SOCs with integrated codecs. |
| VE960 |
The VE960 Series implements a single-channel universal telephone line interface. Low cost, full-featured VoIP PCI cards can be designed by coupling the VE960 device with a PCI to PCM Bridge device.
Legerity's VE960 based PhonePort™ PCI VoIP Reference Design "Le71HR0911G" is available for evaluation. |
| VE980 |
The VE980 series is the world's first integrated solution for voice applications using a HD Audio compliant digital interface. Using a VE980 device provides the most effective way to implement a VoIP-ready PC. The VE980 series implements a single-channel telephone line interface by providing all the necessary voice interface functions from the high voltage subscriber line as well as built-in HD digital interface. Designers benefit by having a simple, cost effective, low-power and dense interface design without sacrificing features or functionality. The VE980 features are crucial for designing cost-effective, full-featured PC VoIP solutions.
Legerity's VE980 based PhonePortTM HD VoIP Reference Design "Le71HR0931" is available for evaluation. |
