7.14.4.1 General
7.14.4 Video expansion port through the X-port
Table 10.
[1]
The expansion port (X-port) can be used either to output 8-bit or 10-bit video from the
comb filter decoder or component path directly or to receive video data from other external
digital video sources such as a MPEG decoder for output at the image port (I-port). The
X-port output is only capable of delivering SDTV signals; HDTV output is only possible
through I-port and H-port.
The input and output direction is switched under the control of bits XPE[2:0] and pin XTRI:
Remark: The I-port configuration controls the enable of the H-port.

Output mode:
– 8-bit dithered (noise shaped) or 10-bit data output of component video Y-C
– The SAV and EAV codes can be inserted optionally for data output, controlled by
– In 10-bit wide video mode the two data LSBs are output on the XRH and XRV
– Clock, synchronization and auxiliary I/O signals accompany the data stream.
Input mode:
– 8-bit data input of component video Y-C
– In input mode, optionally the data bus can be extended to 16-bit by pins HPD[7:0].
– The SAV and EAV codes can be applied optionally for data input, selected by bit
– Clock, synchronization and auxiliary I/O signals accompany the data stream.
