interface optimized for short loop applications.
SLCC (Subscriber Line Control Circuit) functionality with a quad
programmable CODEC and a quad DC-to-DC controllers. The
SLCC supports internal ringing up to 90 V
for Customer Premise Equipment (CPE). The CODEC can be
configured for μ-law, A-law or 16-bit linear PCM encoding. It also
supports a comprehensive set of signaling capabilities required
to supervise and control the telephone lines. These include tone
generation, ring tones, DTMF generation as well as FSK and
metering pulse generation. An on-chip Pulse Width Modulation
(PWM) driver allows control of a per channel DC-to-DC converter
or
Programmable impedance and trans-hybrid balancing allow for
worldwide deployment.
