TION KIT

General Description

The MAX12005 satellite IF switch IC is designed for

multi-user applications supporting two quad universal

low-noise blocks (LNBs) to be matrix switched to four

satellite receivers. The system can be easily expanded

to accept 16 satellite IF inputs using the cascade option

and one additional satellite IF switch IC. A configuration

of eight satellite IF inputs to eight satellite receivers is

also possible by using two ICs and adding eight input

splitters. The insertion loss of these splitters can be com-

pensated by a +6dB or +12dB input gain select.

There are two ways to control the switch function.

Each IC contains four DiSEqC K 2.0 decoders and four

alternate tone/voltage decoders. The decoders use an

integrated trimmed oscillator, simplifying the MAX12005

implementation into any system. There are four opera-

tional modes, which include LNB mode (for use within

the LNB), cascade master mode, cascade slave mode,

and single mode.

The satellite IF switch is designed on an advanced SiGe

process and is available in a lead-free 48-pin TQFN

surface-mount package (7mm x 7mm).
