DS15EA101: Common mode rejection ratio

Carlo

Part Number: DS15EA101

Hi team,


Good day.


What is the common-mode rejection ratio if the circuit is configured as shown in Figure 3. Cable Extender Chipset Connection Diagram for 100Ω Differential Cables?


Regards,
Carlo

    Hi Carlo,

    This common mode rejection depends greatly on mismatch in 75/100 ohm external termination. Impedance termination mismatch is the major factor in determining the CMRR. Please note this mis-match in termination has not been characterized.
