DESCRIPTION The Legerity Le88010 VoicePortTM SLACTM device, in combination with an analog DAA, implements all the voice functions necessary to properly terminate and monitor the customer premises side of a PSTN line and provide linear or G.711 A- or u-Law encoded voice output over a standard PCM or GCI highway. The Le88010 device is ideal for use in voice enabled DSL modems that implement lifeline POTS and support PBX functionality. This device reduces system level cost, space, and power by achieving a high level of voice integration and adds programmability of transmission and signalling features. Designers benefit by having a simple, cost effective, low power and dense, interface design without sacrificing features or functionality. interfaces High speed, pin selectable PCM/MPI or GCI interface Microprocessor interface GCI interface option Programmability -- Two-wire AC impedance -- Input/Output mode selection for one relay driver and five general purpose digital I/O pins. -- Adapts to all ringing frequencies -- Disconnect, line polarity and line-in-use thresholds -- DTMF tone generators -- Dial pulse and DTMF cadence Special feature support -- -- -- -- -- DTMF tones Dial pulses Caller ID pass-through Numeric address signaling On hook transmission Integrated 150 mW 3-V or 5-V Relay Driver LE88010 VOICEPORTTM SLACTM DEVICE BLOCK DIAGRAM PLL PCLK/DCL FS/FSC DXA/DU VINP VINN DRA/DD Voice Signal Processing GCI Interface Supervision Processing PCM Interface and Time Slot Assigner VOUTP VOUTN TDC RDC ITR LTP DCLK/S0 DIN/S1 DTMF and Dial Pulse Generation Microprocessor Interface (MPI) DOUT CS/PG INT/S2 I/O1 - I/O6 6 Input / Output -- Supports lifeline POTS in DSL IAD applications The information in this document is Preliminary and may be changed in whole or in part without notice.
