codecs into a tiny footprint to provide the smallest and lowest cost dual-channel analog
telephone interface. Fully programmable parameters allow global compliance using a
single hardware solution and on-chip functions such as DTMF generation/decoding,
FSK caller ID generation, and modem tone detection help eliminate external DSP
requirements. Integrated test and line monitoring allows remote subscriber loop and
line card diagnostics without centralized test equipment. The Si3220 provides
programmable internal ringing generation for space-constrained CPE applications, and
the Si3225 includes internal ringing relay drivers and ring trip detection to minimize
external components in traditional access applications. The Si3220 and Si3225
operate from a single 3.3 V or 5 V supply and interface directly to standard PCM/SPI
or GCI digital interfaces; all high voltage functions are performed using the Si3200
linefeed interface IC. The Si3220 and Si3225 are packaged in a 64-pin TQFP, and
the Si3200 is packaged in a thermally-enhanced 16-pin SOIC.
