The differential (DIFF_) versions (DIFF_POD10 and DIFF_POD12) use complementary single-ended drivers for outputs, and differential receivers for inputs. Optional untuned split input ODT provides pull-up to VCCO for HP I/O banks. XP5IO leverages calibrated terminations. The untuned on-die source termination feature (OUTPUT_IMPEDANCE) provides the option of 40 Ω, 48 Ω, or 60 Ω of driver impedance. The driver output impedance is set to a default of 40 Ω. POD12 standards also have optional EQUALIZATION and OFFSET_CNTRL (HP I/O banks only) features in the receivers and PRE_EMPHASIS in the drivers.
