General Description
PBL 3799 is an analog Subscriber Line Interface Circuit (SLIC), which is fabricated in a 75 V bipolar, monolithic process.
The programmable, resistive feed circuit incorporates a switch mode regulator to minimize on-chip power dissipation.
Key Features
- On-chip switch mode regulator to minimize power dissipation.
- Programmable, resistive battery feed.
- Line feed characteristics independent of battery variations.
- Tip-ring polarity reversal function.
- Tip and ring open circuit state; tip open with ring active state.
- Detectors: - programmable loop current/ring ground detector - ground key detector - ring trip detector.
- Ring and test relay drivers.
- Line terminating impedance, com.
