High Speed Photo IC
High Speed Photo IC / Short Distance Optical Wireless IC
A new high speed photo IC that outputs the incident light signal as an analog voltage waveform. As a photodetector IC for short distance optical wireless applications, it can be used for visible light communication and more.
Our proprietary photodetector element achieves low capacitance and low noise. A built-in coupling capacitor for DC cutting removes ambient light near DC.
Features
- Frequency 100MHz
- High linearity
- Low noise: noise equivalent power level -44dBm (45nW TYP), with external 100MHz band low-pass filter
- Built-in coupling capacitor for DC cutting removes ambient light near DC
- Light-receiving surface size (1.5mm×1.5mm)
