Final Computed BER Accuracy
Input BER range 1 × 103 to 1 × 1012,
input deterministic jitter (DJ) < 0.4 UI,
DJ ceiling > 1 × 102; asymmetry < 0.1 UI;
requires external data processing algorithms
to implement Q factor extrapolation

BER Accuracy
Input BER range 1 × 103 to 1 × 109,
input DJ = 0 UI, DJ ceiling > 1 × 102;
asymmetry = 0 UI; BER is read as a voltage on
the VBER pin, when the BER mode pin = VEE
