A8287 Overview
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. The device uses a 2-wire bidirectional serial interface, patible with the I2C (Inter-C bus) standard, that operates up to 400 kHz. The A8285 is supplied in a...
