TYPICAL APPLICATIONS
(Continued)
USING THE ML6427 FOR PAL APPLICATIONS
The ML6427 can be optimized for PAL video by adding
frequency peaking to the composite and S-video outputs.
Figure 10 illustrates the use of an additional external
capacitor (330pF) in parallel with the output source
termination resistor. This raises the frequency response
from 1.6dB at 4.8MHz to 0.35dB at 4.8MHz, which
allows for accurate reproduction of the upper sideband of
the PAL subcarrier. Figure 11 shows the frequency
response of PAL video with various values of peaking
capacitors (220pF, 270pF, 330pF and none) between 0 and
10MHz.
For NTSC applications without the peaking capacitor the
rejection at 27MHz is 42dB (typical). For PAL applications
with the peaking capacitor the rejection at 27MHz is 38dB
(typical). See Figure 12. The differential group delay,
shown in Figure 13 with and without a peaking capacitor
(220pF, 270pF, and 330pF and none), varies slightly with
capacitance from 8ns to 13ns.
