B3ZS Decoding DS3/STS-1 Applications
If the XRT7300 is configured to operate in the DS3 or
STS-1 Modes, then the HDB3/B3ZS Decoding Block
performs B3ZS Decoding. When the Decoder is op-
erating in this mode it parses through the incoming
Dual-Rail data and checks for the occurrence of ei-
ther a “00V” or a “B0V” pattern. If the B3ZS Decoder
detects this particular pattern it substitutes these bits
with a “000” pattern.

:
If the B3ZS Decoder detects any bipolar violations
that is not in accordance with the”B3ZS Line Code” format,
or if the B3ZS Decoder detects a string of 3 (or more) con-
secutive “0’s” in the incoming line signal, then the B3ZS
Decoder flags this event as a Line Code Violation by puls-
ing the LCV output pin “High”.
Figure 19 illustrates the B3ZS Decoder at work with
two separate Zero Suppression patterns in the in-
coming Dual-Rail Data Stream.

If the XRT7300 is configured to operate in the E3
Mode, the HDB3/B3ZS Decoding Block performs
HDB3 Decoding. When the Decoder is operating in
this mode it parses through the incoming Dual-Rail
data and checks for the occurrence of either a “000V”

or a “B00V” pattern. If the HDB3 Decoder detects
this particular pattern, it substitutes these bits with a
“0000” pattern.
Figure 20 illustrates the HDB3 Decoder at work with
two separate Zero Suppression patterns in the in-
coming Dual-Rail Data Stream.

If the HDB3 Decoder detects any bipolar violation
(e.g., “V”) pulses that is not in accordance with the HDB3
Line Code format, or if the HDB3 Decoder detects a string
of 4 (or more) “0’s” in the incoming line signal, then the
HDB3 Decoder flags this event as a Line Code Violation by
pulsing the LCV output pin “High”.
