Si3210/Si3211/Si3212 PROSLIC™ PROGRAMMABLE CMOS SLIC/CODEC WIT H RI NG ING /BAT TERY VOLTAGE GENERATIO N Features Performs all BORSCHT Functions Ideal for Short Loop Applications (5 REN at 2 kft, 3 REN at 4 kft) Low Voltage CMOS Package: 38-Pin TSSOP Compliant with Relevant LSSGR and CCITT Specifications Battery Voltage Generated Dynamically with On-Chip DC-DC Converter Controller (Si3210 only) 5 REN Ringing Generator Programmable Frequency, Amplitude, Waveshape, and Cadence Programmable AC Impedance A-Law/µ-Law, Linear PCM Companding On-Hook Transmission Applications Programmable Constant Current Feed (20–41 mA) Programmable Loop Closure and Ring Trip Thresholds with Debouncing Loop or Ground Start Operation and Polarity Battery Reversal Continuous Line Voltage and Current Monitoring DTMF Decoder Dual Tone Generator SPI and PCM Bus Digital Interfaces with Programmable Interrupt for Control and Data 3.3 V or 5 V Operation Multiple Loopback Modes for Testing Pulse Metering FSK Caller ID Generation Terminal Adaptors Cable Telephony PBX/Key Systems Description Wireless Local Loop Voice Over IP Integrated Access Devices The ProSLIC™ is a low-voltage CMOS device that integrates SLIC, codec, and battery generation functionality into a complete analog telephone interface. The device is ideal for short loop applications such as terminal adaptors, cable telephony, and wireless local loop. The ProSLIC is powered with a single 3.3 V or 5 V supply. The Si3210 generates battery voltages dynamically using a software programmable dc-dc converter from a 3.3 V to 35 V supply; negative high-voltage supplies are not needed. All high voltage functions are performed locally with a few low cost discrete components. The device is available in a 38-pin TSSOP and interfaces directly to standard SPI and PCM bus digital interfaces. Functional Block Diagram Ordering Information See page 118.
