Hi,
I'd like to confirm the value of AC coupling cap for SATA only application.
Ii is clear to have the ferrite bead along with 49.9 ohm resistor at between C(TX2) and SATA connector.
For AC coupling capacitor, there are 10nF nearby intel chipset SATA TX and RX already.
- Does it still need all TX1, TX2, RX1, and RX2 A/C coupling capacitors?
- If so, the value is as below, right?
TX1, TX2, and RX2 A/C coupling capacitor : 220nF
RX1 A/C coupling capacitor : 330nF
Thanks
Mark
