Features  
Description  
Superior voice solution with low noise, excellent  
LITELINK III is a single-package silicon phone line  
interface (PLI) DAA used in voice and data  
communication applications to make connections  
between low-voltage equipment and high-voltage  
telephone networks.  
part-to-part gain accuracy  
3 kV  
line isolation  
rms  
Transmit power of up to +10 dBm into 600  
Data access arrangement (DAA) solution for  
modems at speeds up to V.92  
3.3 or 5 V power supply operation  
Caller ID signal reception function  
Easy interface with modem ICs and voice CODECs  
Worldwide dial-up telephone network compatibility  
CPC5620 and CPC5621 can be used in circuits that  
comply with the requirements of TIA/EIA/IS-968  
(FCC part 68), UL1950, UL60950, EN/IEC 60950-1  
Supplementary Isolation compliant, EN55022B,  
CISPR22B, EN55024, and TBR-21  
Line-side circuit powered from telephone line  
Compared to other silicon DAA solutions, LITELINK:  
- Uses fewer passive components  
LITELINK provides a high-voltage isolation barrier, AC  
and DC phone line terminations, switch hook, 2-wire to  
4-wire hybrid, ring detection, and on-hook signal  
detection. LITELINK can be used in both differential  
and single-ended signal applications.  
LITELINK uses on-chip optical components and a few  
inexpensive external components to form a complete  
voice or high-speed data phone line interface.  
LITELINK eliminates the need for large isolation  
transformers or capacitors used in other interface  
configurations. It includes the required high-voltage  
isolation barrier in a surface-mount SOIC package.  
- Takes up less printed-circuit board space  
- Uses less telephone line power  
- Offers simplified operation  
The CPC5620 (half-wave ringing detect) and  
CPC5621 (full-wave ringing detect) build upon IXYS  
Integrated Circuits Division’s LITELINK product line,  
with improved insertion loss control, improved noise  
performance, and lower minimum current draw from  
the phone line. The new mode pin enables worldwide  
implementation.  
- Is a single-IC solution  
Applications  
Computer telephony and gateways, such as VoIP  
PBXs  
Satellite and cable set-top boxes  
V.92 (and other standard) modems  
Fax machines
