CDCLVC1104: [urgency] he output impedance of CDCV304PWR under 3.3V and 1.8V power supply

Jayden Qiu
Intellectual 1325 points
Part Number: CDCLVC1104

Tool/software:

Hi team,

This is FAE Jayden, Please help provide the output impedance of CDCV304PWR under 3.3V and 1.8V power supply, my customer needs it. Because the output signal SI on a certain project board is poor, the matching resistor needs to be readjusted.

Brs

    Jayden,

    This information can be determined from obtaining the slope at the voltage point from Figures 2 and 3 from the data sheet. More info on this E2E thread.

    For 3.3V it should be roughly 25Ω and for 1.8V it should be 22.5Ω (from Figure 3).

    Best,

    Andrea
