DM240-DVB High-Speed Digital Modulator User Interfaces
TM083 – Rev. 3.0 4-9
The Transmit Clock (SCT) supplied by the DM240 is always Output.
Normally, this clock is used to clock the data out of the data source and
then return it to the SCTE input. The DM240 is then set to SCTE mode
eliminating any possible clock skew. Alternately, the data source can
generate the SCTE clock internally and the SCT signal can be ignored. If
SCT mode is selected, the Modulator data clock will not be locked to the
incoming data stream. This mode is NOT recommended except for
testing or fault backup.
