HDB3 Encoder
In single rail mode, the LIU can encode the TPOS input signal to AMI or HDB3 data. With HDB3 encoding
selected, any sequence with four or more consecutive zeros in the input will be replaced with 000V or B00V,
where "B" indicates a pulse conforming to the bipolar rule and "V" representing a pulse violating the rule. An
example of HDB3 encoding is shown in Table 6.
