LF3370’s core. Data may be presented on
input ports A
12-0
, B
12-0
, and C
12-0
as three
channels of non-interleaved input data, one
channel non-interleaved and one channel
interleaved input data, or one channel of
interleaved data (see Table 1 for various
video input schemes). D
12-0
is the Key
channel input port; the Key channel is
simply passed through the input
demultiplexer with a latency that matches
the other three channels.
If video data is non-interleaved and
presented to input ports A
12-0
, B
12-0
, and
C
12-0
, no demultiplexing is performed.
The three channels are passed unmodified
into the LF3370 core with a delay of 3 CLK
cycles. For this operation, bits 0 and 1
must both be set to 1 in Configuration
Register 0 (see Table 5).
If video data is on two channels (see Figure
4), one channel of non-interleaved video
and one channel of interleaved video, it is
assumed that non-interleaved video is
presented to input port A
12-0
