MAX12005ETM+ (MAXIM INTEGRATED PRODUCTS)

The MAX12005ETM+ is a satellite IF switch in 48 pin TQFN package. This 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 satellites IF input to eight satellite receivers is also possible by using two ICs and adding eight input splitters. The insertion loss of these splitters can be compensated by a +6dB or +12dB input gain select. There are two ways to control the switch function. Each IC contains four DiSEqCK 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 operational modes, which include LNB mode (for use within the LNB), cascade master mode, cascade slave mode and single mode.
