The Si3016 is the line-side portion of an integrated silicon Direct Access
Arrangement (DAA) that offers global compliance through a programmable
telephone line interface.
This line-side device digitally connects via Silicon Laboratories' patented
technology to a system-side device that has been integrated into a host
processor or DSP. The device is fully programmable for AC and DC termination,
ringer impedance and ringer threshold and supports billing tone detection,
polarity reversal and pulse dialing, enabling it to meet the most stringent
global PTT requirements. The Si3016 offers a number of new features, including
line voltage monitoring (up to 72 V in 2.25 V/bit resolution), parallel phone
detection, higher transmit/receive levels (up to +3.2 dBm) and lower telephone
line current consumption in on-hook line monitor (caller ID) mode.
Characteristic of Silicon Laboratories' DAA products, the Si3016 offers the
highest level of integration by replacing the codec, isolation transformer,
relays, opto-isolators, 2–4 wire hybrid and DC holding circuit with a single
16-pin small outline package.
