Four Integrated DiSEqC 2.0 Decoders with Integrated Oscillator
Alternate Tone/Voltage Detection
ESD Protected to 2kV HBM

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

There are two ways to control the switch function. Each IC contains four DiSEqC™ 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.

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).

Product Details

The MAX12005 evaluation kit (EV kit) provides a proven PCB layout that facilitates evaluation of the MAX12005 satellite switch RFIC. The EV kit is fully assembled and tested. A software control program with a graphical user interface (GUI) is available (see link below under Tools & Simulations), allowing full user control of the IC functions and settings.

The EV Kit has 75Ω RF lines. However, to make evaluation easy with standard 50Ω test equipment, there are 75Ω to 50Ω impedance transformation networks on-board at all input and output ports.
