Microsemi Corporation Confidential and Proprietary
miSLIC™ Series Solution Overview
The sixth-generation miSLIC line interface solution consists of a miSLIC device, VoicePath API-II (VP-API-II)
Software, and Profiles Data Structures. 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 customer’s 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 Le9643/Le9653 miSLIC device implements a universal telephone line interface with pin-selectable PCM and
SPI or ZSI serial digital interfaces. All AC, DC, and signaling parameters are fully programmable via the PCM and
SPI or reduced pin-count ZSI interfaces.
The switching regulator controller generates the high voltage needed for efficiently powering and ringing analog
telephones. The Le9643 supports two switching regulator architectures, both are capable of ringing 85-VPK; a
Buck-Boost fixed tracking switching regulator architecture which uses a fixed voltage for ringing signals, or an
Inverting-Boost switcher circuit which tracks the ringing voltage during ringing. The Le9653 supports two switching
regulator architectures, both are capable of ringing 140-VPK; a High Voltage Flyback or a High Voltage Inverting-
Boost switcher circuit both of which track the ringing voltage during ringing. The battery tracks the DC feed with
both architectures. The switching regulators provide high efficiency in all operating states and corresponding low
power consumption.
The Le9643/Le9653 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.
