devices implement a complete foreign exchange sta-
tion (FXS) telephony interface solution in a single package that conforms to all relevant
global specifications. The Si3219x ProSLIC ICs operate from a 3.3 V supply and have a
3-wire ISI digital interface with 1.8 to 3.3 V I/O. The Si3219x devices are designed to
operate with a capacitive boost tracking battery supply for lower power, cost, and foot-
print than other tracking supplies in the industry. Self-testing and metallic loop testing
(MLT) are facilitated by the built-in DSP, monitor ADC, and test load. The devices are
available with wideband audio for better-than-PSTN voice quality and DTMF detection.
The Si3219x devices are available in a 4 x 6 mm, 38-pin QFN package.
