(MI) and the LNBA pin, thus leaving all LNB

powering and control functions to the Master

Receiver. This electronic switch is closed when

the device is powered and EN pin is LOW.

The regulator outputs can be logic controlled to

be 13 or 18 V (typ.) by mean of the VSEL pin for

remote controlling of LNBs. Additionally, it is

possible to increment by 1V (typ.) the selected

voltage value to compensate the excess voltage

drop along the coaxial cable (LLC pin HIGH).

DESCRIPTION

Intended for analog and digital satellite receivers,

the LNBK is a monolithic linear voltage regulator,

assembled in Multiwatt-15, 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. It has the same functionality

of the LNBP1X and LNBP20 series, at a reduced

output current capability. 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.

In order to reduce the power dissipation of the

device when the lowest output voltage is

selected, the regulator has two Supply Input pins

V_CC1and V_CC2

They must be powered

respectively at 16V (min) and 23V (min), and an

internal switch automatically will select the

suitable supply pin according to the selected

output voltage. If adequate heatsink is provided

and higher power losses are acceptable, both

supply pins can be powered by the same 23V

source without affecting any other circuit

performance.

The ENT (Tone Enable) pin activates the internal

oscillator so that the DC output is modulated by a

±0.3 V, 22KHz (typ.) square wave. This internal

For slave operation in single dish, dual receiver

systems, the bypass function is implemented by

an electronic switch between the Master Input pin
