(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
VCC1 and VCC2
.
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

oscillator is factory trimmed within a tolerance of
±2KHz, thus no further adjustments neither
external componentsare required.
A burst coding of the 22KHz tone can be
accomplished thanks to the fast response of the
ENT input and the prompt oscillator start-up. This
helps designers who want to implement the
DiSEqC protocols(*).
In order to improve design flexibility and to allow
implementation of newcoming LNB remote
control standards, an analogic modulation input
pin is available (EXTM). An appropriate DC
blocking capacitor must be used to couple the
modulating signal source to the EXTM pin. When
external modulation is not used, the relevant pin
can be left open.
Two pins are dedicated to the overcurrent
protection/monitoring: CEXT and OLF. The
overcurrent protection circuit works dynamically:
as soon as an overload is detected in either LNB
output, the output is shut-down for a time Toff
determined by the capacitor connected between
CEXT and GND. Simultaneously the OLF pin,
that is an open collector diagnostic output flag,
from HIGH IMPEDANCE state goes LOW. After
the time has elapsed, the output is resumed for a
time ton=1/15toff (typ.) and OLF goes in HIGH
IMPEDANCE. If the overload is still present, the
protection circuit will cycle again through toff and
ton until the overload is removed. Typical ton+toff
value is 1200ms when a 4.7µF external capacitor
is used.
This dynamic operation can greatly reduce the
power dissipation in short circuit condition, still
ensuring excellent power-on start up even with
highly capacitive loads on LNB outputs.
The device is packaged in Multiwatt15 for
thru-holes mounting and in PowerSO-20 for
surface mounting. When a limited functionality in
a smaller package matches design needs, a
range of cost-effective PowerSO-10 solutions is
also offered. All versions have built-in thermal
protection against overheatingdamage.
(*): External components are needed to comply to level 2.x and above (bidirectional) DiSEqC bus hardware requirements. DiSEqC is
a trademark of EUTELSAT.
