To simplify matters, the following synonyms are used: SLICOFI-2x: Synonym used for all codec versions SLICOFI-2/-2S/-2S2 SLIC: Synonym used for all SLIC versions SLIC-S/-S2, SLIC-E/-E2 and SLIC-P Chip Set Selection Guide 1 2000-11-09 DuSLIC DuSLIC Chip Set Overview Preliminary 1 DuSLIC Chip Set Overview DuSLIC is a chip set, comprising one dual channel SLICOFI-2x codec and two singlechannel SLIC chips. It is a highly flexible codec/SLIC solution for an analog line circuit and is widely programmable. Users can now access different markets with a single hardware design that meets all different standards worldwide. The interconnections between the single channel high-voltage SLIC and the dual channel SLICOFI-2x codec are a seamless fit. This guarantees maximum transmission performance with a minimum of necessary components. All line circuit functions are implemented on the DuSLIC chip set: * * * * * * * * BORSCHT functions Internal balanced/unbalanced ringing capability up to 85 Vrms Metering by Polarity Reversal and by 12/16 kHz sinusoidal bursts Dual-Tone Multifrequency (DTMF) detection and generation Caller ID generation Three-party Conferencing1) Universal Tone Detection (UTD) unit for fax-/modemtone detection Line Echo Cancellation unit (LEC) Integrated battery switches guarantee minimum power consumption during the off-hook, on-hook and ringing modes. Test and diagnosis functions have been integrated to simplify testing (ITDF). No external test equipment is needed for either subscriber line testing in the field or board testing during production or in the field. Chip Technology The codec devices SLICOFI-2, SLICOFI-2S and SLICOFI-2S2 are manufactured in an advanced 0.35 m 3.3 V CMOS process. The SLIC-E, SLIC-E2 and SLIC-P devices are manufactured in Infineon Technologies robust and well proven 170 V Smart Power technology. The SLIC-S and SLIC-S2 devices are manufactured in Infineon Technologies 90 V Smart Power technology. DuSLIC Architecture Unlike traditional designs, DuSLIC splits the SLIC function into high-voltage SLIC functions and low-voltage SLIC functions. The low-voltage functions are handled in the SLICOFI-2x device. The partitioning of the functions is shown in Figure 1. 1) Cascading DuSLIC channels allows even Multi-party Conferencing Chip Set Selection Guide 2 2000-11-09 DuSLIC DuSLIC Chip Set Overview Preliminary PCM SLIC C SLICOFI-2x IOM(R)-2 SLIC HV SLIC Functions LV SLIC Functions Codec Filter Functions Voltage feeding Transversal current sensing Longitudinal current sensing Overload protection Battery switching Ring amplification On-hook transmission Polarity reversal Programmable DC feeding Ring generation Supervision Teletax generation Teletax notch filter Ring trip detection Ground key detection Hook switch detection Filtering PCM compression/expansion Programmable gain Programmable frequency Impedance matching Hybrid balance DTMF generation DTMF detection FSK generation (Caller ID) Linear mode support (16-bit uncompressed voice data) IOM-2 and PCM/C interface Integrated Test and Diagnosis Functions (IDTF) Line Echo Cancelling (LEC) Universal Tone Detection (UTD) Three-party conferencing Message waiting lamp support ezm14034.wmf Figure 1 DuSLIC Chip Set Chip Set Selection Guide 3 2000-11-09 DuSLIC DuSLIC Chip Set Selection Preliminary 2 DuSLIC Chip Set Selection This chapter summarizes the features of the different DuSLIC chip sets and tries to provide selection criteria for your design.
