Parallel Termination (Thevenin Equivalent)
Conventional Method
Micrel Any-In Internal Termination
Notes:
7. Power-saving alternative to Thevenin termination.
8. Place termination resistors as close to destination inputs as possible.
9. Rb resistor set the DC bias voltage, equal to VT.
10. For 2.5V systems, Rb = 19Ω. For 3.3V systems, Rb = 50Ω.
