DESCRIPTION
1
PCLK_IN
Synchronous
Input
Parallel Data Clock input.
74.25MHz or 74.25/1.001MHz.

Ground
Ground.
Ground power supply connections.

Power
Power.
Positive power supply connections.
5
DET_TRS
Non-
synchronous
Input
Control Signal Input.
Used to enable or disable the detection of
the TRS signals embedded in the video stream. When DET
_TRS is high, the device detects the TRS signals embedded in
the input video stream and uses the detected HVF signals
instead of the external HVF signals. When DET _TRS is low,
TRS detection is disabled. The device uses the external
supplied HVF signals.
6
BLANK
Synchronous
wrt PCLK_IN
Input
Control Signal Input.
When BLANK is low, the device sets the
accompanying LUMA and CHROMA data to their appropriate
blanking levels. When BLANK is high, the LUMA and CHROMA
data streams pass through this stage of the device unaltered.
See timing diagram Figure 3.
7, 17, 95
GND
N/A
Ground.
This pin must be connected to GND for normal
operation.
8
CODE_PROTECT
Non-
synchronous
Input
Control Signal Input.
Used to enable or disable re-mapping of
out-of-range words contained in the active portion of the video
signal. When this signal is high, the device re-maps out-of-
range words contained within the active portion of the video
signal into CCIR-601 compliant words. Values between 000-003
are re-mapped to 004. Values between 3FC and 3FF are re-
mapped to 3FB. When this signal is low, out-of-range words in
the active video region pass through the device unaltered.
9
RSTLN
Synchronous
wrt PCLK_IN
Input
Control Signal Input.
Line number reset signal which must be
asserted once per frame at the beginning of the frame (for
example, on the falling edge of the F signal). A high to low
transition will reset the line number counter of the device to one
(1). See Figure 2 for timing.
10
BP_SC
Non-
synchronous
Input
Control Signal Input.
Used to enable or bypass the SMPTE292M
scrambler and NRZ(I) encoder. When BP_SC is low, the video
stream is scrambled according to SMPTE 292M and NRZ(I)
encoded. When BP_SC is high, the scrambler and NRZ(I)
encoder are by-passed.
11
SRST
Non-
synchronous
Input
Control Signal Input.
Used to reset the SMPTE292M scrambler
and NRZI encoder. When SRST is low, the scrambler and
encoder operate normally. A low to high transition on SRST
causes the scrambler and encoder to reset.
12
TRS_Y/C
Non-
synchronous
Input
Control Signal Input.
Only used when DET_TRS is high. When
TRS_Y/C is high, the device detects and uses TRS signals
embedded in the LUMA (DATA_IN[19:10]) channel. When
TRS_Y/C is low, the device detects and uses TRS signals
embedded in the CHROMA (DATA_IN[9:0]) channel.
