DESCRIPTION
Status signal output.
Indicates a TRS error or a mismatch
between the embedded TRS and the flywheel TRS when the
flywheel is enabled. This signal is set high when an error in the
EAV TRS is detected or when the internal flywheel indicates
there is a mismatching EAV TRS. Refer to Fig. 3 for timing
information of EAV_ERR relative to LUMA (DATA_OUT[19:10])
and CHROMA (DATA_OUT [9:0]).
Test pin.
Used for test purposes only. This pin must be
connected to GND for normal operation.
Must be connected to V
DD
for normal operation.
Must be connected to GND for normal operation.
Input data bus.
DATA_IN [19] is the MSB of the signal (pin 103).
DATA_IN [0] is the LSB of the signal (pin 126).
This data is typically scrambled and not word aligned.

Data enters and exits the device on the rising edge of
PCLK_IN as shown in Figures 1 and 2. This data can be
scrambled or unscrambled and framed or unframed.
2. DESCRAMBLER AND FRAMER
Both the descrambler and framer can be enabled or
disabled independently of each other to allow the input to
remain scrambled or unscrambled. If the data is
unscrambled, it can be word aligned (framed) or passed
through unaltered.
