TS3DS10224: Impedance Setting

Shengyue Zhong
Intellectual 1320 points
Part Number: TS3DS10224


Hi Team,

Customer is using TS3DS10224RUKR chip, INTEL's design proposal requires input impedance to be set to 70ohm and output impedance to be set to 100ohm, can this chip be used this way? If you recommended to follow the design requirements of INTEL, or set the input and output to 85ohm, keep the impedance of the input and output consistent. Thanks.

    Hi Shengyue,

    Since our analog muxes are passive devices, we do not have an input or output impedance of the Sx pins and Dx pins. For the TS3DS10224, we do have an Ron, which is 13Ω(typ), which will be the effective resistance that you will see from S to D on your signal when the switch is on.

    Intel design should be fine

    Thanks!
