1. Requires external components connected as shown in the Applications section. Transmission characteristics are specified assuming a 600 Ω  
resistive termination and ±1% external resistors.  
2. Transmission characteristics are specified assuming a 600 resistive termination; however, feedback using external components allows the  
user to adjust the termination impedance from 600 . Any complex impedance R1 + R2 || C between 300 and 1000 can be synthesized  
using external components.  
3. This parameter is not tested in production. It is guaranteed by design and device characterization.
