To support the miSLIC device, Microsemi offers comprehensive software and hardware collateral packages, including 2-layer printed circuit board reference designs. The VoicePath API-II (VP-API-II) software initializes the FXS port coefficient data containing application or country- specific AC and DC parameters, ringing and other signaling characteristics, and configures the switching power supply. VP-API-II resides on the customers VoIP processor or SoC and provides high-level control over the telephony functions. VP-API-II offers a seamless migration between products utilizing its common software architecture and interfaces with the Microsemi VeriVoice Professional Test Suite Software. A Microsoft Windows GUI (Graphical User Interface) application, VoicePath Profile Wizard (VP Profile Wizard), allows the user to select the operating parameters of the FXS channels and to automatically generate the sets of data structures, called Profiles, that are required by the VP-API-II for integration with the VoIP host software. The Le9622/Le9632 miSLIC device implements a universal telephone line interface with a PCM and SPI interface. This interface is voltage programmable to support 1.8V, 2.5V and 3.3V SoC Processors. All AC, DC, and signaling parameters are fully programmable via the PCM and SPI interfaces The switching regulator controller generates the high voltage needed for efficiently powering and ringing analog telephones. The Le9622 supports two switching regulator architectures. The lowest cost Shared Buck-Boost Automatic Battery Switch (BBABS) architecture uses a fixed voltage for ringing with up to 85V open circuit PK capability. The Multi-Line Inverting-Boost Automatic Battery Switch (ABS) also uses a fixed voltage, with up to 100V open circuit capability. The Le9632 also supports two switching regulator architectures. The High Voltage PK Flyback architecture tracks the ringing voltage during ringing, with up to 140-V capability. The High Voltage PK Inverting-Boost switcher which also tracks the ringing voltage during ringing with up to 125-V capability. The PK battery tracks the DC feed with both architectures. The switching regulators provide high efficiency in all operating states and corresponding low power consumption. The Le9622/Le9632 utilizes the VeriVoice Professional Test Suite Software to resolve line circuit faults and to provide line diagnostics. The integrated digital access to line information such as AC and DC line voltages and Metallic or Longitudinal currents is crucial for remote applications where dedicated test hardware is not cost effective. Additionally, the VeriVoice Manufacturing Software (VVMT) package provides test functions intended to facilitate factory testing, eliminating the need for expensive external test equipment.
