The ABS device can operate from external battery supplies, or from supplies generated by the on-chip switching regulator controllers. This device reduces system level cost, space and power. Designers benefit by having a simple, cost effective, low-power and dense, interface design without sacrificing features or functionality. The programmable, feature rich VoicePort device provides a highly functional line interface which meets the requirements of short and medium loop (up to 1500 Ohms total at 1 REN) applications. Features include: high voltage switching regulator, self-test, line test capabilities, integrated ringing (up to 110 Vpk), worldwide software programmability with wideband capability, flexible signal generator with tone cadencing and caller ID generation. These VoicePort device features are crucial for designing cost-effective, fullfeatured Voice over Broadband solutions. Features • Highest level of integration • Smallest footprint • Pin-compatible options • Lowest cost of ownership Benefits • Reduces system BOM and discrete component count • Saves board space • Provides design flexibility to develop one design and populate the voice socket with the right features for a given market—100 V or 120 V, internal balanced (sinusoidal or trapezoidal) • Provides the most cost-effective BOM for 2-channel applications • Offers design flexibility to develop one application for worldwide markets • Highly programmable • Integrated ring cadencing and system state control • Reduces real-time software overhead • Common application programming interface • Significantly reduces development time with VoicePath API-II software • Comprehensive line sensing • Enables high performance GR-909 diagnostics and subscriber loop test and self test support with VeriVoice Test Suite software • Integrated switching regulator • Enables lowest component count and highest efficiency in all states of operation Le88266/286 VoicePort Devices SoC MPI & PCM Highway Pin-compatible options for 100V/120 V ABS Switching Regulator Controller A/D & D/A Tip & Ring Driver Linear/G.711 Internal Balanced & Unbalanced Ringing Voice Signal Processor, Supervision, and Test Functions A/D & D/A 2-Channel FXS 2 Zarlink Semiconductor Inc.
