General Description
A7540 is a low-cost 4 x 2 switch matrix with tone detector in a 24-lead QFN package for use in RF multiplexing applications from 200 to 3000 MHz. A positive voltage controlled 4 bit decoder and tone/polarity detector are both integrated on the switch with DiSEqC control signals rejection. A7540 is ok to be used in 50/75 ohm systems.
Switch outputs (OP1 & OP2) can be independently selected from any of the four inputs (HH, HL, VH, VL) or simultaneously select the same inputs. Note that the switch is bi-directional and input/output functionality may be interchanged.
