The LE792388 Next Generation Octal Subscriber Line Audio-processing Circuit (SLAC), in combination with the single channel LE79271 or dual LE79272 SLIC, implements a DSL friendly, high density 8-channel universal telephone line interface with wideband capability. This enables the design of a low cost, high performance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable via a microprocessor interface. The LE792388 has an integrated test tool box which can be used standalone or for high density line cards you can offload a lot of the basic call control and test functions to the LE79124 or LE79128 VCP to help manage calls or resolve faults to the line or line circuit. A full API is available to run on a host processor to simplify software integration. **Low Density Chip Set:** Octal SLAC (codec) + Long Loop SLICs [Le792388 (codec)](https://www.microchip.com/wwwproducts/en/LE792388) + [Le79271 (SLIC)](https://www.microchip.com/wwwproducts/en/LE79271) / [Le79272 (Dual SLIC)](https://www.microchip.com/wwwproducts/en/LE79272) [ZL792588 (codec with External/ Internal Ringing)](https://www.microchip.com/wwwproducts/en/ZL792588) + [Le79271 (SLIC)](https://www.microchip.com/wwwproducts/en/LE79271) / [Le79272 (Dual SLIC)](https://www.microchip.com/wwwproducts/en/LE79272)

The Le87100 device is a single-channel differential amplifier designed to drive PLC high-power signals. The Le87100 device contains a pair of wide-band amplifiers designed with Microchip’s HV15 bipolar SOI process for high-power output with low-power consumption. Line driver gain is set externally to the device. The device can be powered from a single high-voltage supply or from dual supplies. The device can be programmed to one of three preset bias levels to optimize power and performance. In addition, the line driver features a power down state, which forces low-power and high-impedance mode for receive transmissions or for idle operations. The control pins respond to input levels that can be generated with a standard GPIO, but are tolerant of higher voltage logic levels. The Le87100 device is available in a 16-pin (4 mm x 4 mm) QFN package with an exposed pad for enhanced thermal conductivity.
