SI3206

Si3241/Si3206/Si3203 Quad ProSLIC® Programmable CMOS SLIC/Codec Description ProSLIC® - Software programmable parameters: - Ringing frequency, amplitude, cadence, and waveshape The Quad is a series of low-voltage CMOS devices that integrate both SLIC and codec functionality into a single IC to provide a complete four-channel analog telephone interface in accordance with all relevant Telcordia, ITU, and ETSI specifications. The Si3241 includes internal ringing generation to eliminate centralized ringers and ringing relays. On-chip subscriber loop and audio testing allows remote diagnostics and fault detection with no external test equipment or relays. The Quad ProSLIC devices operate from a single 3.3 V supply and interface to standard PCM/SPI or GCI bus digital interfaces. The Si3206/3 linefeed interface IC performs all high-voltage functions and operates from a 3.3 V supply as well as three battery supplies up to –135/–110 V. The Quad ProSLIC devices are available in a 100-pin thin quad flat package (TQFP), and the Si3206/3 is available in a thermallyenhanced 48-pin thin quad flat package (TQFP) or 40-pin quad flat no-lead (QFN) package. - Features - Performs all BORSCHT functions - Ideal for applications up to 20 kft (6 km) - Internal adaptive balanced ringing to –135 VPK (Si3206) and –110 VPK (Si3203) - Internal unbalanced ringing - Power offloading - Low power consumption - 2.5 Vrms pulse metering (12/16 kHz) - Two-wire ac impedance - Transhybrid balance - DC current loop feed (10–50 mA) - Loop closure and ring trip thresholds - Ground key detect threshold - Power alarms Automatic switching of up to three battery supplies On-hook transmission Loop or ground start operation Smooth polarity reversal DTMF decoder Dual tone generators Caller ID generator A-Law/µ-Law companding, linear PCM PCM and SPI bus digital interfaces with programmable interrupts GCI/IOM-2 mode support 3.3 V operation GR-909/844 loop diagnostics Audio diagnostics with loopback Pb-free/RoHS compliant packages Digital loop carrier (DLC) line cards Central office (CO) line cards Integrated voice and data (IVD) line cards Private Branch Exchange (PBX) systems Key telephone systems Optical networking terminals (ONT) VoIP Gateways Applications SLIC CODEC ADC DAC CODEC ADC DAC Si3206 or Si3203 Si3206 or Si3203 RING Linefeed Monitor Programmable AC Impedance and Hybrid Channel 1 DTMF & Tone Gen Si3206 or Si3203 Si3206 or Si3203 TIP Linefeed Control PCM/GCI SPI CODEC ADC DAC CODEC ADC DAC SLIC Linefeed Control Linefeed Monitor TIP Channel 3 RING Caller ID SLIC Linefeed Control Linefeed Monitor TIP Channel 2 RING Ringing Generator Line Diagnostics SLIC Linefeed Control Linefeed Monitor TIP Channel 4 RING DSP ProSLIC Copyright © 2007 by Silicon Laboratories 7.17.07 Si3241/Si3206/Si3203 Quad ProSLIC® Programmable CMOS SLIC/Codec Selected Electrical Specifications Parameter Ambient Temperature Supply Voltage, Si324x Supply Voltage, Si3206/3 High Battery Voltage, Si3206/3 Low Battery Voltage Maximum Loop Resistance (loop + load) DC Differential Output Resistance Idle Channel Noise PSRR from VDD Longitudinal to Metallic/PCM Balance (forward or reverse) Metallic/PCM to Longitudinal Balance Longitudinal Impedance Longitudinal Current per Pin DC Current 2-Wire Return Loss Transhybrid Balance Thermal Resistance, (eTQFP-100) Continuous Power Dissipation, (eTQFP-100) Thermal Resistance (QFN-40) Continuous Power Dissipation (QFN-40) θJA PD θJA PD TA = 85 °C TA = 85 °C Symbol TA VDD VDD VBATH VBATL RLOOP RDO ILOOP=18 mA, VBAT = –48 V ILOOP < ILIM C-Message weighted RX and TX, dc to 3.4 kHz 200 Hz to 1 kHz 1 kHz to 3.4 kHz 200 Hz to 3.4 kHz 200 Hz to 3.4 kHz at TIP or RING Active off-hook 200 Hz to 3.4 kHz VTR = 0 V 200 Hz to 3.4 kHz 300 Hz to 3.4 kHz Test Condition F-Grade G-Grade Min 0 –40 3.13 3.13 –9 –9 — 160 — 40 58 53 40 — — — 26 26 — — — — Typical 25 25 3.3 3.3 — — — — 8 — 63 58 — 50 — — 30 30 25 1.6 32 1.7 Max 70 85 3.47 3.47 –135/–110 VBATH 2000 640 10 — — — — — 30 50 — — — — — — Unit °C °C V V V V Ω Ω dBrnC dB dB dB dB Ω mApk mA dB dB °C/W W °C/W W Package Information D D1 E1 E 100 PIN 1 DESIGNATOR A A1 A2 b D D1 e E E1 Min — 0.05 0.95 0.17 — — — — — MM Typ — — — 0.22 16.00 14.00 0.50 16.00 14.00 Max 1.20 0.15 1.05 0.27 — — — — — 100-Pin ETQFP 1 e A A2 Bottom Side Exposed Pad 5.0 x 5.0 mm L b A1 MM Min A A1 b D D2 e E E2 L L1 aaa bbb ccc ddd Typ Max 0.80 0.90 1.00 0.00 0.02 0.05 0.18 0.25 0.30 6.00 BSC 4.10 4.30 4.40 0.50 BSC 6.00 BSC 4.10 4.30 4.40 0.30 0.40 0.50 0.03 0.05 0.08 — — — — — — — — 0.10 0.10 0.08 0.10 40-Pin QFN ProSLIC Copyright © 2007 by Silicon Laboratories Silicon Laboratories and Silicon Labs are trademarks of Silicon Laboratories Inc.
