Example
The designer uses LVDCI_18 driver with 65Ω reference resistors. The LVDCI_18 SSO limit
for 50Ω impedance is first taken from
11 SSO per V
SSO Limit LVDCI_18 at 65Ω = ((65Ω)/50Ω) × 11 = 14.3
Bank 0 in all devices contains only configuration and dedicated signals. Since there is no
user I/O in Bank 0, no SSO analysis is necessary for this bank.

/GND pin pair. Therefore, the SSO limit for LVDCI_18 at 65Ω is:
