| Si3226/7 and SI3208/9 Dual ProSLIC(R) with DC-DC Controller Description ProSLIC(R) - Software-programmable parameters: - Ringing frequency, amplitude, cadence, and waveLoop or ground start operation Smooth polarity reversal DTMF generator/decoder A-Law/-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 Customer Premises Equipment (CPE) Optical Network Terminals (ONT) Private Branch Exchange (PBX) Cable EMTAs, ATAs, VoIP Gateways shape Two-wire ac impedance Transhybrid balance DC current loop feed (10-45 mA) Loop closure and ring trip thresholds Ground key detect threshold 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). - Features Performs all BORSCHT functions Ideal for short- or long-loop applications Internal balanced or unbalanced ringing Low power consumption Integrated dc-dc controller Wideband CODEC (Si3227) Applications Low-power sleep mode On-hook transmission Si3226/7 Si3226 DRX DTX CS SDI SDO SCLK INT RST Si3206 SI3208/9 CODEC ADC DAC CODEC ADC DAC SLIC Linefeed Linefeed Control Linefeed Monitor DTMF & Tone Gen Caller ID Programmable Programmable AC Impedance AC Impedance and Hybrid FSYNC PCM/ GCI Interface TIP Channel 1 RING SPI Control Interface Ringing Generator DSP SLIC Linefeed Linefeed Control Linefeed Monitor Line Diagnostics PLL DC-DC Controllers DC-DC Controller VBAT VDC DC-DC BOM TIP Channel 2 RING PCLK ProSLIC Copyright (c) 2007 by Silicon Laboratories 6.1.07 Si3226/7 and SI3208/9 Dual ProSLIC(R) with DC-DC Controller Selected Electrical Specifications Parameter Ambient Temperature Supply Voltage, Si322x Supply Voltage, Si3209/8 Battery Voltage, Si3209/8 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 (QFN-40) Continuous Power Dissipation (QFN-40) JA PD TA = 85 C Symbol TA VDD VDD VBAT 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 -- 160 -- 40 58 53 40 -- -- -- 26 26 -- -- Typical 25 25 3.3 3.3 -- -- -- 8 -- 60 58 -- 50 -- -- 30 30 32 1.7 Max 70 85 3.47 3.47 -135/-110 2000 640 12 -- -- -- -- -- 30 45 -- -- -- -- Unit C C V V V dBrnC dB dB dB dB mApk mA dB dB C/W W Package Information 64-Pin TQFP MM Min A b D D1 e E E1 -- Typ -- Max 1.20 0.27 0.17 0.22 12.00 BSC 10.00 BSC 0.50 BSC 12.00 BSC 10.00 BSC 40-Pin QFN Min A A1 b D D2 e E E2 L L1 0.80 0.00 0.18 4.10 MM Typ 0.90 0.02 0.25 4.30 Max 1.00 0.05 0.30 4.40 6.00 BSC 0.50 BSC 6.00 BSC 4.10 0.30 0.03 4.30 0.40 0.05 4.40 0.50 0.08 ProSLIC Copyright (c) 2007 by Silicon Laboratories Silicon Laboratories and Silicon Labs are trademarks of Silicon Laboratories Inc.
