shows the HVIO output buffer impedance of the i.MX50 processor.
HVIO 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 line. 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
Rpu
Rpd
Low drive strength, Ztl = 150 Ω
Medium drive strength, Ztl = 75 Ω
High drive strength, Ztl = 50 Ω
Low drive strength, Ztl =1 50 Ω
Medium drive strength, Ztl = 75 Ω
High drive strength, Ztl = 50 Ω
