Designed for use in challenging environments, the Silver Telecom ST003 is a single Subscriber Line Interface Circuit (SLIC) in a 21 pin Dual-in-Line (DIL) format. The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost, minimising time to market for Telephony Systems developers.
The ST003 has been designed to work with loop lengths of typically 3.0km. Its performance to regulatory standards (G712) allows use in public and private network applications. With operation over an extended temperature range of -55C to +85C, ST003 is suitable for use in Industrial and Military Telecoms applications.
The ST003 has integral DC/DC converter and ringing generation thus providing all the line powering requirements from a single supply. The SLIC requires minimal external components.
The system interface has been designed for direct connection to popular codecs, for both audio and signalling.
The ST003 is ideal for low line count, short loop length applications, such as ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI), Wireless Local Loops (WLL) and Small Office Home Office (SOHO).
Product Features
- wide temperature range -55C to +85C
- 600R impedance
- Very small DIL package
- Very Simple integration
- On-board ringing generator
- Integral high efficiency DC/DC converter, providing: Ringing voltage and Loop current
- Single supply voltage (3.3v)
- Tip/Ring polarity reversal
- Simplified protection
