8943RDA/-D/-DFR — Instruction Manual 29
Configuration
Auto Reclock/Mute
In this mode the electrical inputs are equalized and fed to the reclocker. The
module will analyze the input to determine whether the bit rate is 270Mb/s
(SD), 1485Mb/s (HD), or 2970Mb/s (3G). If the input signal matches one of
these rates, the signal is reclocked at the determined data rate and passed
to the electrical output line drivers. If the signal is determined to not be one
of these rates, the electrical outputs of the reclocker will be muted and the
outputs of the cable driver will be static.
3G 2970M
In this fixed reclock 3G mute mode, the inputs are equalized and fed to the
reclocker. The module will analyze the input to determine if the bit rate is
2970Mb/s (3G). If it is, the module will reclock the signal at 2970Mb/s and
feed it to the electrical output drivers. If the signal is determined not to be
2970Mb/s, the electrical outputs of the reclocker will be muted and the
cable driver outputs will be static.
HD 1485M
In this fixed reclock HD mute mode, the inputs are equalized and fed to the
reclocker. The module will analyses the input to determine if the bit rate is
1485Mb/s. (HD) If it is, the module will reclock the signal at 1485b/s and
feed it to the electrical output drivers. If the signal is determined not to be
1485Mb/s, the electrical outputs of the reclocker will be muted and the
cable driver outputs will be static.
SD 270M
In this fixed reclock SD mute mode, the inputs are equalized and fed to the
reclocker. The module will analyze the input to determine if the bit rate is
270Mb/s (SD). If it is, the module will reclock the signal at 270Mb/s and
feed it to the electrical output drivers. If the signal is determined not to be
270Mb/s, the electrical outputs of the reclocker will be muted and the cable
driver outputs will be static.
Manual Bypass HD/3G
In this mode, the inputs are equalized and the reclocker is always bypassed.
This selection should be made when using a 1485Mb/s or 2970Mb/s data
rate or data so that the output drivers will be set to the proper slew rate
(slope) for HD signals.
Manual Bypass SD
In this mode, the inputs are equalized and the reclocker is always bypassed.
This selection should be made when using a 270Mb/s data rate or to pass
data so that the output drivers will be set to the proper slew rate (slope) for
SD signals.
