MAX12005 19-5554 Rev 1 10/11 Satellite IF Switch General Description Features The MAX12005 satellite IF switch IC is designed for S 8-Input-to-4-Output Matrix Switch multi-user applications supporting two quad universal S Expandable to 16 Inputs with Cascade Master/ low-noise blocks (LNBs) to be matrix switched to four Slave Option satellite receivers. The system can be easily expanded S 950MHz to 2150MHz Operation to accept 16 satellite IF inputs using the cascade option and one additional satellite IF switch IC. A configuration S Greater than 30dB Switch Isolation of eight satellite IF inputs to eight satellite receivers is S 0/+6/+12dB Input Stage Gain Selection to also possible by using two ICs and adding eight input Compensate for Splitter Insertion Loss splitters. The insertion loss of these splitters can be com- Gain Step for All Input Stages Is Commonly pensated by a +6dB or +12dB input gain select. Controlled Through an Analog Select Pin There are two ways to control the switch function. S Four Integrated DiSEqC 2.0 Decoders with Each IC contains four DiSEqCK 2.0 decoders and four Integrated Oscillator alternate tone/voltage decoders. The decoders use an S Alternate Tone/Voltage Detection integrated trimmed oscillator, simplifying the MAX12005 S ESD Protected to 2kV HBM 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).
