Complete BORSCHT function for 2 channels in a single VoicePort device DESCRIPTION Battery Feed, Over-voltage support, integrated Ringing, line Supervision, Codec, Hybrid (2W/4W), Test The Microsemi dual channel Le88276 Tracking Battery Integrated Power Management VoicePort device implements a dual-channel telephone line Integrated high voltage switching regulator controllers interface by providing all the necessary voice interface Wide input voltage range (VSW =+4.75V to +35V) functions from the high voltage subscriber line to the P/DSP Switching power supply tracks line voltage digital interface. This device reduces system level cost, space, minimizing active & ringing state power dissipation and power. Designers benefit by having a simple, cost Low power Idle and On-hook transmission states effective, low-power and dense, interface design without Worldwide Programmability sacrificing features or functionality. The programmable, feature rich VoicePort device provides a highly functional line interface Two-wire AC impedance, Balance Impedance, Gain which meets the requirements of short and medium loop (up to DC feed voltage and current limit 1500 total) applications. Features include: high voltage Ringing frequency, voltage and current limit switching regulator, self-test, line test capabilities, integrated 12 kHz and 16 kHz Metering ringing (up to 140-Vpk), worldwide software programmability Programmable loop closure and ring trip thresholds with wideband capability, flexible signal generator with tone Ringing cadencing, caller ID generation and all BORSCHT functions. 5 REN These VoicePort device features are crucial for designing cost- Up to 140-Vpk internal balanced sinusoidal or effective, full-featured Voice over Broadband solutions. trapezoidal ringing with programmable DC offset Unbalanced ringing for PBX trunk compatibility VOICEPORT DEVICE BLOCK DIAGRAM Powerful signal generator VBAT 1 Universal Caller ID generation TIPD 1 High PCLK/DCL Up to 4 simultaneous tones PLL TIPT 1 Voltage RINGT FS/FSC 1 Line Driver Automatic cadencing feature RINGD 1 DXA/DU GCI Interface Voice DRA/DD TAC 1 VoicePath API-II Software available to implement (GCI) RAC Signal 1 RTV Processing 1 FXS functions LFC PCM Interface 1 Signaling RSN and Time Slot 1 Control Supports device calibration IHL 1 Assigner (PCM) TDC Supervision TSCA 1 Line configuration via VoicePath Profile Wizard RDC Processing 1 4 Input / Output I/O2 - I/O1 i i Signal VeriVoice Test Suite Subscriber Loop Test Generation DCLK/S0 Signal DIN/S1 Microprocessor Seamless integration with VP-API-II software Generation DOUT Interface CS/PG RDC Supervision (MPI) Utilizes integrated self test capabilities 2 INT/S2 TDC Processing 2 RST Line fault detection and reporting IHL 2 Signaling SWCMPY RSN 2 Control SWVSY Pin selectable PCM/MPI or GCI interface LFC 2 SWISY Switching RTV Voice SWOUTY 2 regulator G.711 -law, A-law, or 16 bit linear coding RAC Signal SWCMPZ 2 controllers TAC Processing SWVSZ 2 SWISZ Wideband 16 kHz sampling mode RINGD 2 High SWOUTZ RINGT 2 Voltage TIPT Analog Integrated 150 mW 3-V Relay Driver 2 Line Driver TIPD Reference 2 External catch diode required VBAT VREF IREF 2 Small footprint package - Exposed pad 80-pin LQFP 1 Microsemi Corporation Copyright 2014, Microsemi Corporation.
