SI32911-A-FS

Si3217x and Si3291x ProSLIC® Single-Chip FXS Solution with FXO Option Description - The Si3217x is a family of pin-compatible single-channel ProSLIC products that implement a complete foreign exchange station (FXS) telephony interface solution in accordance with all relevant LSSGR, ITU and ETSI specifications. Select parts in the series also implement Silicon Laboratories' patented capacitive isolation technology to enable seamless connection to Si3291x series foreign exchange office (FXO) line-side devices. The Si3217x ProSLIC ICs operate from a 3.3 V supply and interface to standard PCM/SPI digital interfaces. The Si3217x integrated dc-dc controller automatically generates the optimal battery voltages required for each line-state. Si3217x ICs are available with voltage ratings of –110 V or –135 V to support a wide range of ringing voltages. The Si3217x is available in a 5x7 mm 42-pin QFN package. The Si3291x is available in a 16-pin SOIC package. Low power standby operation Tracking dc-dc controller Patented low-power ringing Wideband voice support DTMF detection Pulse metering 3.3 V operation Pb-free/RoHS-compliant packaging Si3291x Features - Greater than 5 kV isolation - Global programmability - Up to +6 dBm TX/RX level - Parallel handset detection - Type I and II caller ID support - Integrated ring detector - Programmable digital hybrid Applications - Customer Premise Equipment (CPE) - VoIP DSL Gateways and Routers - Wireless Local Loop (WLL) - Integrated Access Devices (IAD) - Analog Terminal Adapters (ATA) - Small Office/Home Office (SOHO) PBX Si3217x Features - Performs all BORSCHT functions - Ideal for short to medium loops - Global programmability - Simplified configuration and diagnostics - Supported by ProSLIC API Ordering Guide FXS P/N Description Max Vbat Temperature Si32176-B-FM FXS, wideband capable –110 V 0 to 70 °C Si32176-B-GM FXS, wideband capable –110 V –40 to 85 °C Si32177-B-FM FXS, wideband capable –135 V 0 to 70 °C Si32177-B-GM FXS, wideband capable –135 V –40 to 85 °C Si32178-B-FM FXS, DTMF detection, wideband capable with FXO support –110 V 0 to 70 °C Si32171-B-FM FXS, DTMF detection, pulse metering –110 V 0 to 70 °C Si32171-B-GM FXS, DTMF detection, pulse metering –110 V –-40 to 85 °C Region Ringer Thresholds On-hook Speeds RoHS Compliant Temperature FCC/CTR21 1 2 Yes 0 to 70 °C Si32919-A-FS Global 3 3 Yes 0 to 70 C PCM/ GCI Interface Caller ID CS SDI SDO SCLK INT RST PCLK DTMF & Tone Gen SPI Control Interface Ringing Generator DSP Line Diagnostics PLL DC-DC DC-DC Controller Controller Si3217x ProSLIC CODEC SLIC ADC ADC Linefeed Control DAC DAC Linefeed Monitor Optional FXO TIP RING C1A C1B C2A C2B Isolation Interface Control Isolation Interface Hybrid and dc Termination RX DCT VREG IGND Ring Detect Off-Hook CID QB QE FXS TIP FXO BOM DRX DTX Linefeed FSYNC Programmable Programmable AC ACImpedance Impedance and Hybrid FXO P/N Si32911-A-FS RING Si3291x Copyright © 2009 by Silicon Laboratories 4.14.09 Si3217x and Si3291x ProSLIC® Single-Chip FXS Solution with FXO Option Selected Electrical Specifications Parameter Ambient Temperature Symbol TA Test Condition Min Typical Max Unit F-Grade 0 25 70 °C G-Grade –40 25 85 °C Supply Voltage, Si3217x VDD 3.13 3.3 3.47 V Battery Voltage, Si3217x VBAT –15 — –136/–110 V Maximum Loop Resistance  (loop + load) DC Differential Output  Resistance RLOOP ILOOP=18 mA, VBAT = –48 V — — 2000  RDO ILOOP < ILIM 160 — 640  Idle Channel Noise C-Message weighted — 8 12 dBrnC RX and TX, dc to 3.4 kHz — 55 — dB 200 Hz to 1 kHz 58 60 — dB 1 kHz to 3.4 kHz 53 58 — dB 200 Hz to 3.4 kHz 40 — — dB 200 Hz to 3.4 kHz at TIP or RING — 50 —  Active off-hook 200 Hz to 3.4 kHz — 25 — mA VTR = 0 V — — 45 mA 2-Wire Return Loss 200 Hz to 3.4 kHz 26 30 — dB Transhybrid Balance 300 Hz to 3.4 kHz 26 30 — dB — 32 — °C/W PSRR from VDD Longitudinal to Metallic/PCM  Balance (forward or reverse) Metallic/PCM to Longitudinal Balance Longitudinal Impedance Longitudinal Current per Pin DC Feed Current See Table 5, Si3217x Data Sheet Thermal Resistance (QFN-42) θJA Thermal Resistance (SOIC-16) θJA — 85 — °C/W Continuous Power Dissipation (QFN-42) PD TA = 85 °C — 1.3 — W Continuous Power Dissipation (SOIC-16) PD TA = 85 °C — 0.47 — W Package Information 42-Pin QFN MM M in Typ M ax A 0.60 0.65 0.70 b 0.20 0.25 0.30 D D2 5.00 BS C 3.35 3.40 e E 16-Pin SOIC 7.00 BS C E2 5.35 5.40 5.45 E3 1.65 1.70 1.75 E4 3.15 3.20 3.25 L 0.35 0.40 0.45 L1 0.05 0.10 0.15 Min Max A — 1.75 A1 0.10 0.25 A2 1.25 — b 0.31 0.51 c 0.17 0.25 D 9.90 BSC E 6.00 BSC E1 3.90 BSC e 1.27 BSC L 0.40 L2 ProSLIC 3.45 0.50 BS C 1.27 0.25 BSC h 0.25 0.50 ø 0° 8° Copyright © 2009 by Silicon Laboratories Silicon Laboratories and Silicon Labs are trademarks of Silicon Laboratories Inc.
