Legerity Introduces Highly Integrated VoIP Solution with Broadcom9 March 2005
Legerity, Inc., the "V" in VoIP(TM), today announced at Spring VON 2005 the expansion of the VE950 Family with the addition of the pin compatible Le9500A, Le9500B and Le9500C devices. The Le9500 devices are high voltage Subscriber Line Interface Circuits (SLICs) that are optimized for short-loop, power sensitive applications. Together, a Broadcom VoIP codec/DSP and a Le9500 device provide a high performance, low cost VoIP solution.

The Le9500 SLIC devices operate from a 3.3V and a single high voltage supply -- up to 100V. The devices are offered in 75, 85 and 95V operating battery voltages to meet the most stringent ringing requirements. Both differential ringing and differential inputs make the Le9500 devices ideal for direct interface to data over cable service interface specification (DOCSIS) compliant products such as cable modem gateways, multimedia adaptors, and residential gateways like the Broadcom BCM3341, BCM3351, BCM3352, BCM1101 and equivalent products.
"Legerity continues to lead the industry in the development and innovation of products for the VoIP IC market. Manufacturers who choose Broadcom for their reference platform can now easily complete a design with the most cost effective and highest performing VoIP-optimized SLIC on the market," said Mike Stibila, vice president of marketing and applications for Legerity. "Moreover, because of Legerity's innovative design capabilities, designers can use one reference design to generate multiple products from low to high voltage."
While the Le9500 devices support higher battery voltages for longer loops and higher REN applications, they also dissipate very little power -- only 31mW in the scan state and 43mW in the active state. Because the Le9500 devices are pin compatible, they offer customers an integrated high voltage solution that includes differential ringing and a codec interface, on board ringing generation, ultra low on-hook power and high battery flexibility.
The Le9500A, Le9500B and Le9500C devices are available for production orders today. These VE950 products are targeted toward consumer premise equipment (CPE) such as voice enabled cable modems, DSL modems, gateways, and media terminal adapters (MTA). In addition, these devices are ideal for FTTx, WLL, PBX, and other SME applications. The Le9500A is targeted at $1.95 per device in high volume. More information on the new devices can be found at www.legerity.com.
