Product data sheet
The input/output data relation limits overall H and V zooming.
The video scaler receives its input signal from the video decoder or from the expansion
port (X-port). It gets 16-bit Y-C
27 MHz from the decoder. A discontinuous data stream can be accepted from the
expansion port (X-port), normally 8-bit wide ITU-656 like Y-C
pixel qualifier on pin XDQ.
The scaler operation is defined by two programming pages A and B, representing two
different tasks, that can be applied field alternating or to define two regions in a field (e.g.
with different scaling range, factors and signal source during odd and even fields).
