It is available in the 128-TQFP Exposed Pad package. The packaging is shaped in a Cut Tape (CT)-shape, which makes it easy to carry around. Regulating the temperature to 0°C~70°C is crucial to ensuring reliable operation. If you use a 1.8V 2.5V 3.3VV power supply, you should have no problem. A 128 termination can be found in it. Supply voltages of 1.2V can achieve high efficiencies. KSZ9897 numbers are members of the family.
