regulator (parallel interface)
Feature summary
■ Complete interface for two LNBs remote supply and control
■ LNB selection and stand-by function ■ Built-in tone oscillator factory trimmed at
22KHz
■ Fast oscillator start-up facilitates DiSEqCTM encoding
■ Two supply inputs for lowest dissipation ■ Bypass function for slave operation ■ LNB short circuit protection and diagnostic ■ Auxiliary modulation input extends flexibility ■ Cable length compensation ■ Internal over temperature protection ■ Backward current protection
Description
Intended for analog and digital satellite receivers, the LNBP is a monolithic linear voltage
regulator, assembled in PowerSO-20 and PowerSO-10, specifically designed to provide the powering voltages and the interfacing signals to the LNB downconverter situated in the antenna
