Notes on Operation
1. Connection to RF amplifiers
The CXA1753M features the voltage-output type and the voltage-input type such as the CXA1610M should
be used as RF amplifiers. The noise tolerance will be greatly improved over that of conventional
photodiodes used with current-input RF amplifiers.
2. Power supply
The CXA1753M can be used either with a dual power supply or with a single power supply.
However, this IC is not provided with a center voltage generating circuit, and so when used with a single
power supply the center voltage must be supplied by an RF amplifier or some other device. For instance
when the CXA1610M is used as an RF amplifier, the V
C
input pin of the CXA1753M should be connected to
the VR output pin of the CXA1610M.
In addition, note that Pin 3 is internally connected to Pin 7 (GND).
Power supply connections for each case are as follows.
For both a dual power supply and a single power supply, the voltage difference between the V
CC
and GND
pins should be within the range of 2.8 V and 11.0 V.
