CPC5610/CPC5611
LITELINK™ II Silicon Data Access Arrangement (DAA) IC
Features
Description
• Full-duplex data and voice transmission
• Transformerless telephone line isolation interface
• Operates at all modem speeds, including V.90 (56K)
• 3.3 or 5 V power supply operation
Clare CPC5610 and CPC5611 LITELINKs are silicon
data access arrangement (DAA) ICs used in data and
voice communication applications to make connec-
tions to the public switched telephone network
(PSTN). LITELINK uses on-chip optical components
and a few inexpensive external components to form a
complete voice or high-speed data telephone line
interface.
• Half-wave ring detector (CPC5610) or full-wave ring
detector (CPC5611)
• Caller ID signal reception
• Small 32-pin SOIC plastic package
• Printed-circuit board space and cost savings
• Meets PC Card (PCMCIA) height requirements
• Easy interface with modem ICs and voice CODECs
• Worldwide dial-up telephone network compatibility
• Supplied application circuit complies with the
requirements of TIA/EIA/IS-968 (FCC part 68),
UL1950, UL60950, EN60950, IEC60950,
EN55022B, CISPR22B, EN55024, and TBR-21
• CPC5610 and CPC5611 comply with UL1577
• TTL compatible logic inputs and outputs
• Line-side circuit powered from telephone line
LITELINK eliminates the need for the large isolation
transformers or capacitors as used in other DAA con-
figurations. It incorporates the required high-voltage
isolation barrier in the surface-mount SOIC package.
The CPC5610 (half-wave ring detect) and CPC5611
(full-wave ring detect) build upon Clare’s existing
LITELINK line, with improved performance and 3.3 V
operation.
