shows the UHVIO output buffer impedance.
UHVIO Output Buffer Impedance
Symbol
Output driver impedance is measured with long transmission line of
impedance Ztl attached to I/O pad and incident wave launched into
transmission lime. Rpu/Rpd and Ztl form a voltage divider that defines
specific voltage of incident wave relative to OVDD. Output driver
impedance is calculated from this voltage divider (see
