LITELINK™ Silicon DAA,
Phone Line Interface
The LITELINK™ phone line interface is the industry’s only
single package silicon Data Access Arrangement, featuring a
32-pin, small outline, low profile, surface mount package. It is
ideal for both voice and data (V.22bis to V.90/V.92) and
applications in particularly dense circuit environments. The
internal optical isolation barrier eliminates high cost transformer
or capacitive isolation circuits. This solution saves cost relative
to competitive circuits through reduced passive component
count and smaller printed circuit board space.
The 3kV
regulatory requirements. The optical isolation barrier yields low
distortion performance necessary for high speed
communications. In addition, the LITELINK™ application circuit
is capable of surviving 6kV (10usec x 700usec) lightning surge
waveforms (K.21) making it the most robust silicon DAA on the
market.
Features
• Voice and data applications
• Modem DAA for speeds up to V.92
• Half-wave or full-wave ringing detection
• Worldwide telephone network compatibility
• Caller-ID reception
• Line side powered from telephone line
• 3.3V to 5V power supply
• Easy interface with modem ICs and voice codecs
• High power transmit option for voice applications (>3dBm)

Caller ID
LITELINK™ offers the lowest operational phone line quiescent
current. The device easily interfaces to commonly available
standard single-ended or differential voice and modem codecs
on the market. Contact Clare for information on codec reference
designs that offer programmable AC termination impedance for
global applications. LITELINK™ complies with international
PSTN agency requirements.
The newest device is the CPC5622, which is part of the
LITELINK™ III product family. It offers continuous Caller-ID
(CID) signal reception which is ideal for telephony applications
in countries where CID information is present before the ringing
signal. The CPC5622 also offers both full and half wave ringing
signal detection allowing the designer to choose the appropriate
interface to the codec/DSP block.
