Analog Input
RTD2363 integrates three ADCs (analog-to-digital converters), one for each color (red, green, and
blue). The sync-processor can deal
with Separate-Sync, Composite-Sync, Sync-On-Green, and Sync-On-Y.
And the PLL can generate very low jitter clock from HS to sample the analog signal to digital data.
Input data is latched within a
capture window defined in registers refer to VS and HS leading edge. There are two sets of ADC input
pins in RTD2363 whose
internal switch can select one of them to display.
RTD2363 owns a capability to display YPbPr input source which normally come from DVD Player or
Setup-Box etc.. The YPbPr
source can be into 1st or 2nd ADC pins.
TMDS Input
RTD2363 integrates high-speed single link receiver and high bandwidth content protection (HDCP)
function. It can operate up to
165Mhz. It can effectively deal with the weak signal in long cable application which often cause signal
loss.
Scale-Down
The Scale-down function are basically composed of horizontal scale-down and vertical scale-down.
The horizontal scale-down can
config as linear or non-linear scale-down. In non-linear scale-down, we can set three segment for
different scaling ratio in order to
keep image detail less-lost in the center area and express the side area which we expect it less
important.
The low-pass filter in front of H/V scale-down plays a role of anti-aliasing filter. Moreover, the filter
prior to vertical scale-down can
be config as high-pass filter to serve as vertical peaking filter.
