FEATURES
Differential ringing and codec interface Single-ended application also supported On-board ringing generation
— 15 to 70 Hz ring frequency supported Three ringing options: — Sine wave input - sine wave output — PWM input - sine wave output — Square wave input - trapezoidal output Flexible power supply options: — VBAT2 for active talking — VBAT1 for ringing, scan, and so on — 3.
3 V for VCC Battery switch to minimize off-hook power Eight operating states: — Scan — Forward and reverse battery active — Forward and reverse battery on-hook transmission — Ground start — Ring — Disconnect Ultra-low on-hook power: — 29 mW scan state — 38 mW active state Loop start, ring trip, and ground start detection — Fixed off hook threshold with hysteresis — Fixed ground start threshold with hysteresis — Fixed ring-trip threshold as a function of battery voltage Software-controllable dual-current limit option — 25 mA or 40mA via ground or open control input UL1950 Compatible — When not in ringing, |VTIP| and |VRING| are clamped to be less than 56.
