LNBP20CR Product details

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 via the coaxial cable. Since most satellite receivers have two antenna ports, the output voltage of the regulator is available at one of two logic-selectable output pins (LNBA, LNBB). When the IC is powered and put in Stand-by (EN pin LOW), both regulator outputs are disabled to allow the antenna downconverters to be supplied/controlled by others satellite receivers sharing the same coaxial lines. In this occurrence the device will limit at 3 mA (max) the backward current that could flow from LNBA and LNBB output pins to GND. (See continuous description).

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
