... Voice over Broadband applications. Its goal is to reduce system level costs, space, and power through higher levels of integration, and to reduce the total cost of ownership by offering better quality of service. The Le9502 RSLIC device provides a totally configurable solution to the BORSCHT functions for two lines. The resulting system is less complex, smaller, and denser, yet cost effective with minimal external components ...

... PRODUCT DESCRIPTION The VE950 series Le9502 RSLIC device uses reliable, dielectrically isolated, fully complementary bipolar technology to implement BORSCHT functions for short loop applications. Internal power dissipation is minimized by two independent line voltage tracking, buck-boost switching regulators. Two power supplies are required: 3.3 V and a positive supply (V level clock is required to drive the switching regulator ...
