CXA1753M

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 VC 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.

Dual power supply

Single power supply

(9) VCC

(7) GND

For both a dual power supply and a single power supply, the voltage difference between the VCC and GND

pins should be within the range of 2.8 V and 11.0 V.
