Select parts in the series also implement Skyworks Solutions' patented capacitive isolation technology to enable seamless connection to Si3291x series foreign exchange office (FXO) line-side devices. The Si3217x Pro SLIC 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. See the Ordering Guide for the voltage rating of each Si3217x version. The Si3217x is available in a 5 x 7 mm 42-pin LGA package. The Si3291x is available in a 16-pin SOIC package. Functional Block Diagram FSYNC DRX DTX CSb SDI SDO SCLK INTb RSTb PCLK PCM/ GCI...
