LNBP21PDT-TR

The LNBP21PDT-TR is a type of INBP supply and control IC, which is designed to provide the power and the 13/18V, 22KHz tone signalling to the LNB. Intended for analog and digital satellite STB receivers/SatTV, sets/PC cards.

Features of LNBP21PDT-TR are: (1)complete interface between lnb and I2CTM bus; (2)built-in DC/DC controller for sin gle 12V supply operation; (3)accurate built-in 22KHz tone oscillator; (4)suits widely accepted standards; (5)fast oscill ator start-up facilitates diseqctm encoding; (6)built-in 22KHz tone detector supports bi-directional diseqctm; (7)loop-through function for slave operation; (8)LNB short circuit protection and diagnostic; (9)cable length digital compensat ion, etc.

The absolute maximum ratings of the LNBP21PDT-TR can be summarized as: (1)DC input voltage: 16V; (2)DC output pin voltage:-0.3V to 22V; (3)logic input voltage:-0.3V to 7V; (4)detector input signal amplitude: 2Vpp; (5)logic high output voltage: 7V; (6) bypass switch on current :900mA; (7)bypass switch off voltage:±20V; (8)gate current:±400 mA; (9)operating junction temperature range:-40°C to+125°C.
