Si3226/7 and Si3208/9 Dual ProSLIC® with DC-DC Controller Description ProSLIC® - Software-programmable parameters: - Ringing frequency, amplitude, cadence, and waveLoop 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 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 © 2007 by Silicon Laboratories 6.1.07 Si3226/7 and Si3208/9 Dual ProSLIC® 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) θJA 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 Ω Ω dBrnC dB dB dB dB Ω 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 © 2007 by Silicon Laboratories Silicon Laboratories and Silicon Labs are trademarks of Silicon Laboratories Inc.
