CXA2598M

Notes on Operation

1. Connection to RF amplifier

The voltage input-type RF amplifier should be used because the CXA2598M is the voltage output type. The

noise allowance is dramatically increased compared to the case where the conventional photodiode and the

current input-type RF amplifier are used.

2. Power supply

The CXA2598M can be used with a single power supply or dual 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 from the RF amplifier or some other device.

(Pin 1) VCC

(Pin 12) GND

Dual power supply Positive power supply Negative power supply

Single power supply Positive power supply

GND

(Pin 6) VC

GND

Center voltage

The potential difference between the Vcc pin and the GND pin should be in the range of 4.5 to 5.5V in both of

a single power supply and dual power supply.

3. Soldering

The reflow soldering is not guaranteed for the CXA2598M.

4. Mechanical strength for package

The mechanical strength for the package is not guaranteed for the CXA2598M.

Do not employ the mounting method which gives much weight to the package.

5. Visual inspection standard

Another specifications and limit samples must be exchanged regarding visual inspection standards for the

photodetector.
