2 General Description
A7533 is a low-cost 4 x 2 switch matrix with tone detector
in a 20-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. A7533 is ok to be used in 50/75 ohm systems.

OP1
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.
