Product data sheet
7.8 Image port output interface
Table 6.
The output interface consists of an output formatter, a FIFO for video and for sliced text
data, an arbitration circuit which controls the mixed transfer of video and sliced text data
over the I-port and a decoding and multiplexing unit which generates the 8-bit or 16-bit
wide output data stream and the accompanied reference and supporting information.
The clock for the output interface can be derived from an internal clock (decoder or
X-port), from the second internal PLL set (registers PLL2 and CGC2) or from an externally
provided clock which is appropriate for e.g. VGA and frame buffer. The clock can be up to
54 MHz.
The scaler provides the following video related timing reference events (signals) through
pins IPG0, IGP1, IGPH, IGPV and IDQ:
