Si3226/7 and Si3208/9 Dual ProSLIC® with DC-DC Controller Description - Software-programmable parameters: - Ringing frequency, amplitude, cadence, and wave- ProSLIC® The Dual is a family of low-voltage CMOS devices that integrate both SLIC and CODEC functionality into a single IC. In combination with a linefeed IC (LFIC), they provide a complete twochannel analog telephone interface in accordance with all relevant LSSGR, ITU, and ETSI specifications. The Dual ProSLIC devices (Si3226/7) operate from a single 3.3 V supply and interface to standard PCM/SPI or GCI bus digital interfaces. The LFICs (Si3208/9) perform all high-voltage functions and operate from a 3.3 V supply as well as highvoltage battery supplies. The Si3208 is rated for – 110 V, and the Si3209 is rated for –135 V. The Dual ProSLIC devices are available in a 64-pin thin quad flat package (TQFP), and the LFICs are available in a 40-pin, quad flat no-lead package (QFN). shape Two-wire ac impedance Transhybrid balance DC current loop feed (10–45 mA) Loop closure and ring trip thresholds Ground key detect threshold - Features Performs all BORSCHT functions Ideal for short- or long-loop applications Internal balanced or unbalanced ringing Low power consumption Integrated dc-dc controller Applications - Low-power sleep mode On-hook transmission Customer Premises Equipment (CPE) Optical Network Terminals (ONT) Private Branch Exchange (PBX) Cable EMTAs, ATAs, VoIP Gateways FSYNC DRX DTX PCM/ GCI Interface Caller ID CS SDI SDO SCLK INT SPI Control Interface Ringing Generator DSP Si3206 Si3208/9 CODEC SLIC ADC Linefeed Control DAC Linefeed Monitor CODEC SLIC ADC Linefeed Control DAC Linefeed Monitor Line Diagnostics RST PCLK DTMF & Tone Gen Programmable Programmable AC ACImpedance Impedance and Hybrid Si3226 Si3226/7 DC-DC DC-DCControllers Controller PLL Linefeed Wideband CODEC (Si3227) Linefeed - Loop or ground start operation Smooth polarity reversal DTMF generator/decoder 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 loop diagnostics Audio diagnostics with loopback Pb-free/RoHS-compliant packaging TIP Channel 1 RING TIP Channel 2 RING VBAT VDC ProSLIC DC-DC BOM Copyright © 2007 by Silicon Laboratories 6.1.07 Si3226/7 and Si3208/9 Dual ProSLIC® with DC-DC Controller 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, Si322x VDD 3.13 3.3 3.47 V Supply Voltage, Si3209/8 VDD 3.13 3.3 3.47 V Battery Voltage, Si3209/8 VBAT –9 — –135/–110 V Maximum Loop Resistance (loop + load) DC Differential Output Resistance RLOOP ILOOP=18 mA, VBAT = –48 V — — 2000 Ω RDO ILOOP < ILIM 160 — 640 Ω 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 C-Message weighted — 8 12 dBrnC RX and TX, dc to 3.4 kHz 40 — — 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 — Ω Active off-hook 200 Hz to 3.4 kHz — — 30 mApk 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 — 1.7 — W Thermal Resistance (QFN-40) θJA Continuous Power Dissipation (QFN-40) PD TA = 85 °C Package Information 64-Pin TQFP MM Min Typ Max A — — 1.20 b 0.17 0.22 0.27 D 12.00 BSC D1 10.00 BSC e 0.50 BSC E 12.00 BSC E1 10.00 BSC 40-Pin QFN MM Min Typ Max A 0.80 0.90 1.00 A1 0.00 0.02 0.05 b 0.18 0.25 0.30 D D2 e E ProSLIC 6.00 BSC 4.10 4.30 4.40 0.50 BSC 6.00 BSC E2 4.10 4.30 4.40 L 0.30 0.40 0.50 L1 0.03 0.05 0.08 Copyright © 2007 by Silicon Laboratories Silicon Laboratories and Silicon Labs are trademarks of Silicon Laboratories Inc.
