μPC7073 ANALOG SUBSCRIBER LINE LSI (BS-SLIC)
The μPC7073 is a BS-SLIC that can be used in analog subscriber circuits such as private branch exchangers (PBXs) and switching equipment for central offices. It features two of the functions required for analog subscriber circuits: subscriber line feed control and subscriber line supervision.
Use of the μPC7073 in combination with a digital CODEC (μPD9903) can reduce the number of components required in analog subscriber circuits.
FEATURES
? Single-chip, monolithic LSI (bipolar)
? Constant-resistance feed or semi constant-current feed Note
? 200-? feed, 400-? feed, or Tip-to-Ring pin feedout status (HIGH and WET)
? On-chip metering signal superposing circuit
? On-hook sending and receiving
? Loop detection Note
? Ground detection and ground-fault/power contact protection Note
? Three on-chip relay drivers (flyback prevention diode must be externally provided)
? Two power supply voltages (–48 V and +5 V)
? Low power consumption: 110 mW (TYP., when on hook)
