Remark: Due to bandwidth considerations XPSC[5:0] and
XACL[5:0] can be chosen differently to the previously
mentioned equations or Table 12, as the H-phase scaling
is able to scale in the range from zooming up by factor 3 to
downscaling by a factor of 1024
8191.
Figures 33 and 34 show some resulting frequency
characteristics of the prescaler.
Table 12 shows the recommended prescaler
programming. Other programmings, other than given in
Table 12, may result in better alias suppression, but the
resulting DC gain amplification needs to be compensated
by the BCS control, according to the equation:
Where:
2XDCG[2:0]
≥ DC gain
DC gain = (XC2_1 + 1)
× XACL[5:0] + (1 XC2_1).
For example, if XACL[5:0] = 5, XC2_1 = 1, then the
DC gain = 10 and the required XDCG[2:0] = 4.
The horizontal source acquisition timing and the
prescaling ratio is identical for both the luminance path and
chrominance path, but the FIR filter settings can be
defined differently in the two channels.
Fade-in and fade-out of the filters is achieved by copying
an original source sample each as first and last pixel after
prescaling.
Figures 31 and 32 show the frequency characteristics of
the selectable FIR filters.
