The TLV672x transfer curve is shown in
figure below.
- VIT+ represents the
positive-going input threshold that causes the comparator output (M_RSTn,
M_LPWn) to change from a logic low state to a logic high state.
- VIT- represents the
negative-going input threshold that causes the comparator output (M_RSTn,
M_LPWn) to change from a logic high state to a logic low state.
- The internal hysteresis is the
difference between VIT+ and VIT-.
The minimum and maximum input
thresholds are precision trimmed to be sufficiently away from the minimum and
maximum OSFP and OSFP-XD MSA voltage zones for proper host-to-module
signalling.
