Transition Timing
The transition words require interconnect bandwidth
and displace control data. Therefore, control data is not
sampled (see Figure 9):
Two clock cycles before DE_IN goes high
During the video phase
Two clock cycles after DE_IN goes low
The last sampled control data are latched at the deserial-
izer control data outputs during the transition and video
phases. Video data are latched at the deserializer RGB
data outputs during the transition and control phases.
Applications Information
AC-Coupling Benefits
AC-coupling increases the common-mode voltage to
the voltage rating of the capacitor. Two capacitors are
sufficient for isolation, but four capacitors—two at the
serializer output and two at the deserializer input—pro-
vide protection if either end of the cable is shorted to a
high voltage. AC-coupling blocks low-frequency
ground shifts and common-mode noise. The MAX9247
serializer can also be DC-coupled to the MAX9248/
MAX9250 deserializers.
Figures 10 and 12 show an AC-coupled serializer and
deserializer with two capacitors per link. Figures 11 and
13 show the AC-coupled serializer and deserializer with
four capacitors per link.
Selection of AC-Coupling Capacitors
See Figure 14 for calculating the capacitor values for
AC-coupling depending on the parallel clock frequen-
cy. The plot shows capacitor values for two- and four-
capacitor-per-link systems. For applications using less
than 18MHz clock frequency, use 0.125μF capacitors.
Frequency-Range Setting RNG[1:0]
The RNG[1:0] inputs select the operating frequency
range of the MAX9247 serializer. An external clock with-
in this range is required for operation. Table 3 shows
the selectable frequency ranges and corresponding
data rates for the MAX9247.
