Sequence Start Marker
Figure 17.
T5557 Sequence Start Marker in Extended Mode
The T5557 sequence start marker is a special damping pattern, which may be used to
synchronize the reader. The sequence start marker consists of two bits (‘01’ or ‘10’)
which are inserted as header before the first block to be transmitted if the bit 29 in
extended mode ist set. At the start of a new block sequence, the value of the two bits is
inverted.
Inverse Data Output
The T5557 supports in its extended mode (X-mode) an inverse data output option. If
inverse data is enabled, the modulator as shown in Figure 18 works on inverted data
(see Table 4). This function is supported for all basic types of encoding.
Figure 18.
Data Encoder for Inverse Data Output
Fast Write
In the optional fast write mode the time between two gaps is nominally 12 field clocks for
a ‘0’ and 27 field clocks for a ‘1’. When there is no gap for more than 32 field clocks after
a previous gap, the T5557 will exit the write mode. Please refer to Table 5 and Figure 8.
