Description

The STEVAL-CBL004V1 demonstration board

implements a DC-DC converter based on the

LNBH24 dual LNB supply and control IC with

step-up and I

This simple, cost-effective design represents an

integrated solution for supplying/interfacing two

independent LNB down-converters in satellite

antenna dishes. It provides good performance

with a minimum of external components.

The STEVAL-CBL004V1 includes all the functions

needed for the design of dual tuner STBs, with

supplying/interfacing functions that are compliant

with the international standards.

It features an I

fully integrated step-up DC-DC converter, it works

Complete interface between LNBs and I

Built-in DC-DC converter for single 12 V supply

operation (8 - 15 volt V

efficiency (typ. 93%@0.5 A)

Compliant with main satellite receiver output

voltage specifications

Accurate 22 kHz tone generator supports

bidirectional DiSEqC™ 2.0 and meets widely

accepted standards (patent pending)

Fast oscillator startup facilitates DiSEqC™

encoding

Overload and overtemperature internal

protection with I

Output voltage and output current level

diagnostic feedback through I

LNB short-circuit dynamic protection

+/- 4 kV ESD tolerant on output power pins

RoHS compliant
