MAX12005 satellite if switch 19-5554; rev 1; 10/11 + denotes a lead(pb)-free/rohs-compliant package. * ep = exposed paddle. ordering information 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). applications direct broadcast satellite receivers satellite if distribution l-band distribution features s 8-input-to-4-output matrix switch s expandable to 16 inputs with cascade master/ slave option s 950mhz to 2150mhz operation s greater than 30db switch isolation s 0/+6/+12db input stage gain selection to compensate for splitter insertion loss gain step for all input stages is commonly controlled through an analog select pin s four integrated diseqc 2.0 decoders with integrated oscillator s alternate tone/voltage detection s esd protected to 2kv hbm diseqc is a trademark of eutelsat. evaluation kit available part temp range pin-package MAX12005etm+ -40 n c to +85 n c 48 tqfn-ep*

MAX12005 satellite if switch 8 detailed description the MAX12005 satellite if switch features eight 75 i inputs with three selectable gain steps of 0, +6db, and +12db. each of the eight input amplifiers feeds into four nine-to-one multiplexers with the switching controlled by voltage/tone or diseqc signaling from up to four receivers. the output of each multiplexer is then sent to a satellite receiver through a 75 i buffered output stage. the satellite if switch has four modes of operation. two modes are used to increase the number of if inputs by cascading two MAX12005 ics together. the first ic is set to master mode to enable the four cascade inputs. the second ic is set to slave mode with its outputs connected to the cascade inputs of the master ic. the lnb mode sets up the ic to recognize lnb diseqc signaling to control switching and ignore diseqc signaling for multiswitch applications. the single mode sets up the ic to recognize multiswitch diseqc signaling to control switching and ignore lnb diseqc signaling. for the lnb, single, and slave modes, the four cascade inputs are disabled. input gain select the voltage supplied to the gain_select pin provides the selection for one of three gain settings available at all eight input stages, as follows: gnd = 0db 1/2 v cc = +6db v cc = +12db the +6db gain step voltage can be set through the use of a simple supply voltage-divider. this gain select feature is intended to compensate for input signal losses due to the use of input rf signal splitters. chip mode select the voltage supplied to the mode_select pin provides the selection for one of four ic operational modes, as follows: gnd = lnb mode 1/3 v cc = slave mode (cascade operation) 2/3 v cc = master mode (cascade operation) v cc = single mode the slave mode and master mode voltages can be set through the use of simple supply voltage-dividers. switch control voltage/tone signaling is the default switch control after power-up or when a receiver is connected or recon - nected with the die power on. after an individual decoder receives a diseqc signal, that decoder switches from voltage/one control to diseqc control until a new receiver connection is made or when the ic has a power-on reset. layout considerations to minimize coupling between different sections of the ic, a star power-supply routing configuration with a large decoupling capacitor at a central v cc node is recom - mended. the v cc traces branch out from this node, each going to a separate v cc node in the circuit. place a bypass capacitor as close as possible to each sup - ply pin. this arrangement provides local decoupling at each v cc pin. use at least one via per bypass capacitor for a low-inductance ground connection. do not share the capacitor ground vias with any other branch. the MAX12005 ev kit can be used as a starting point for layout. for best performance, take into consideration grounding and routing of rf, baseband, and power- supply pcb proper line. make connections from vias to the ground plane as short as possible. on the high- impedance ports, keep traces short to minimize shunt capacitance. ev kit schematic and gerber files can be found at www.maxim-ic.com . spi is a trademark of motorola, inc.
