PRODUCT SPECIFICATION
DHSYNC are referenced to the input data (0HFLAT) and not
the output of the LSTORE1, i.e. 1HFLAT.
The duration of the DVSYNC signal is fixed to one line and
the duration of the DHSYNC signal is 64 clock periods.
Both these signals are generated by the internal horizontal
and vertical state machines.
The falling edge of these signals relative to the data matches
the requirements of the TMC22x91 family of digital encod-
ers.
AVOUT Active Video (Output Pin)
The decoder produces an active video signal starting 4 PCK
before the programmed start of active video and ending 4
PCK after the programmed end of active video. This signal is
used in both the video mixer (TMC22x8x) family and the
digital encoder (TMC22x9x) family. The end points of this
signal are flagged by the internally generated SAV and EAV
signals.
VBLK (Vertical Blanking Period)
The vertical blanking period conforms to the CCIR 656
specification for D1 component data streams. This signal is
decoded from the line ident, LID
Table 18. Vertical Blanking Period
BBLK (Vertical Burst Blanking Period)
The vertical burst blanking blanks the lines with no burst
from the burst phase locked loop. This signal is controlled by
the video standard and the field count. The burst blanking
signal is active low.
**
Signal is available over the microprocessor data bus.
