A8285 Product details

Description

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.
