Intended for analog and digital satellite receivers, the LNB (low noise block) converter regulator is a monolithic linear and switching voltage regulator, specifically designed to provide power and interface signals to an LNB downconverter, via coaxial cable.
Features
- LNB selection and standby function.
- Provides up to 500 mA load current.
- Two-wire serial I2C interface.
- Built-in tone oscillator, factory-trimmed to 22 kHz;
facilitates DiSEqC™ 2.0 encoding.
- Auxiliary modulation input.
- 22 kHz tone detector facilitates DiSEqC™ decoding
(A8287 only).
- Tracking switch-mode power converter for lowest
dissipation.
- LNB overcurrent protection and diagnostics.
- Internal overtemperature protec.
