The NT22030 is a full-custom CMOS IC designed for high-speed LED drive for applications such as Fast Ethernet over POF.
The drive current can be set by an external resistor (defined as two 15 k Ω resistors in parallel) using the |MODSET pad or using an on-chip resistor by connecting |MODSET to GND.
3 dB optical power reduction functionality is also supported by connecting this pad to VCC.
The NT22030 driver IC will be supplied in die form, with a clearly visible orientation.
