ZL79258 Octal External Ringing Subscriber Line Audio- processing Circuit, Next Generation Carrier Chipset (NGCC) Document ID :136868 Version 6 April 2016 POTS Features Ideal for high density, medium and large line Ordering Information count applications 1 ZL792588GDG2 196-pin BGA Tray Wideband 16 kHz sampling mode capability 1. The 196-Pin BGA is a green package that meets RoHS API-compatible with VE790 Series designs Directive 2002/95/EC of the European Council to minimize the environmental impact of electrical equipment. High performance digital signal processor provides programmable control of all major line card functions Description A-law/-law and linear codec/filter The ZL79258 Next Generation Octal External Ringing Transmit and receive gain, Two-wire AC Subscriber Line Audio-processing Circuit (SLAC) impedance, Transhybrid balance, Equalization device is used in both the FXS or POTS application and in the Metallic Loop Test or MeLT application. DC loop feeding In the POTS application, in combination with the External battery-backed or earth-backed Le79271 SLIC device or Le79272 dual SLIC, the SLAC ringing implements a high density eight-channel universal Internal ringing generation telephone line interface with wideband capability for internal or external ringing applications. This enables Loop supervision and ring-trip detection the design of a low cost, high performance, fully Metering generation and shaping (12 kHz and software programmable line interface with worldwide 16 kHz) applicability. All AC, DC, and signaling parameters are programmable via a microprocessor interface. Enhanced line control DTMF and Modem Tone Detection In the MeLT application, in combination with the ZL75816 Driver Test Access Switch (DTAS), Tone generation (DTMF, FSK, and arbitrary implements a complement MeLT test head for up-to tone) 128 channels. Test Tool Box as part of integrated FXS test There are different firmware loads for the SLAC for the routines POTS or MeLT application that are available from Standard PCM and MPI digital interfaces Microsemi. General purpose I/O pins, can be used as relay drivers or for control of the Microsemi Driver Test Access Switch Device (DTAS) in a MeLT Applications application POTS MeLT Features DSLAM Driver and Multiplexor Control for up to 128 DLC, CO Channels PBX/KTS Current Sense and Voltage Driver to implement Microsemis Metallic Line Test Algorithms MeLT Generation of Wetting Current on dry-DSL or ADSL or VDSL DSLAM g.fast lines VDSL2 or G.Fast DPU Test Tool Box for data capture and manipulation 1 Microsemi Corporation Confidential and Proprietary CONFIDENTIALZL79258 Data Sheet Block Diagram - POTS 2 Current Sense Ch1 VDD33 8 Voltage Feed Ch1 4 A /B 1 1 VDD18 SLIC LD1 4 Voltage Sense Ch1 AVDDxx 2 6 DGND Current Sense Ch2 8 8 Voltage Feed Ch2 AGND A2/B2 SLIC LD2 8 IO 0, IO 1 Voltage Sense Ch2 2 TSCA,TSCB Current Sense Ch3 8 DRA,DRB Voltage Feed Ch3 A3/B3 SLIC LD3 DXA,DXB Voltage Sense Ch3 2 FS Current Sense Ch4 8 PCLK Voltage Feed Ch4 A /B 4 4 SLIC LD4 CS Voltage Sense Ch4 2 RST NGSLAC Current Sense Ch5 8 INT Voltage Feed Ch5 A /B 5 5 SLIC LD5 DCLK Voltage Sense Ch5 DIN 2 DOUT Current Sense Ch6 8 Voltage Feed Ch6 A /B 6 6 IREF SLIC LD6 SLB BATL Voltage Sense Ch6 2 SHB BATH Current Sense Ch7 8 SPB BATP Voltage Feed Ch7 A7/B7 SLIC LD7 Voltage Sense Ch7 2 Current Sense Ch8 8 Voltage Feed Ch8 A8/B8 SLIC LD8 Voltage Sense Ch8 2 P0-P2, SEL XSB XSC Block Diagram - MeLT 2 LD1 VDD33 4 VDD18 A /B 1-16 1-16 CAL1 -from GPIO DTAS 4 EN 1:2 from GPIO AVDDxx 6 Current Sense Ch1-32 6 Voltage Feed Ch1-32 DGND 8 2 AGND Voltage Sense Ch 1-32 EN 1:2 from GPIO A /B 17-32 17-32 DTAS A0-A2 -from GPIO TSCA,TSCB 1 DRA,DRB DXA,DXB NGSLAC FS LD2 PCLK A /B 33-48 33-48 DTAS CAL2 -from GPIO EN 1:2 from GPIO CS 6 Current Sense Ch 33-64 Voltage Feed Ch 33-64 RST 2 INT Voltage Sense Ch 33-64 DCLK EN 1:2 from GPIO A /B DIN 49-64 49-64 DTAS A0-A22 -from GPIO DOUT IREF SLB BATP LD3 SHB BATH SPB CAL from GPIO +12V 3 A65-80/B65-80 DTAS EN 1:2 from GPIO 6 Current Sense Ch 65-96 Voltage Feed Ch 65-96 2 Voltage Sense Ch 65-96 EN 1:2 from GPIO A81-96/B81-96 A0-A2 from GPIO DTAS 3 P0-P2, SEL 2 Microsemi Corporation - CMPG CONFIDENTIAL
