HD-LINX ™ GS1510
HDTV Serial Digital Deformatter
PRELIMINARY DATA SHEET
DESCRIPTION
• SMPTE 292M compliant
When interfaced to the Gennum GS1545 HDTV Equalizing
Receiver or GS1540 Non-Equalizing Receiver, the GS1510
performs the final conversion to word aligned data. The
device performs NRZI decoding and de-scrambling as per
SMPTE 292M and word-aligns to the incoming data stream.
Line based CRCs are calculated on the incoming data
stream and are compared against the CRCs embedded
within the data stream.
• standards detection/indication for SMPTE 292M levels
A/B,C,D/E,F,G/H,I,J/K,L/M
• NRZI decoding and SMPTE descrambling with
BYPASS option
• line CRC calculation, comparison
• selectable line based CRC re-Insertion
• H, V, F timing reference signal (TRS) extraction
• selectable flywheel for noise immune H, V, F extraction
• selectable automatic switch line handling
• selectable TRS and line number re-insertion
• selectable active picture illegal code re-mapping
HVF timing information is extracted from the data stream. A
selectable internal HVF flywheel provides superior noise
immunity against TRS signal errors. The device also detects
and indicates the input video signal standard.
The GS1510 can detect and re-map illegal code words
contained within the active portion of the video signal. Prior
to exiting the device, TRS, Line Numbers and CRCs based
on internal calculations may be re-inserted into the data
stream.
• configurable FIFO LOAD pulse
• 20 bit 3.3V CMOS input data bus
• optimized input interface to GS1545 or GS1540
• single +3.3V power supply

F_E/S
Nonsynchronous
Input
Control Signal Input. Used to control where the FIFO_L signal
is generated. When F_E/S is high, the GS1510 generates
FIFO_L signal at EAV. When F_E/S is low, the GS1510
generates FIFO_L signal at SAV. See Fig. 4 for timing
information.
6
MUTE
Synchronous
wrt PCLK_IN
Input
Control Signal Input. Used to enable or disable blanking of
the LUMA (DATA_OUT[19:10]) and CHROMA
(DATA_OUT[9:0]). When MUTE is low, the device sets the
accompanying LUMA and CHROMA data to their appropriate
blanking levels. When MUTE is high, the LUMA and CHROMA
data streams pass through this stage of the device unaltered.
7
FW_EN/DIS
Nonsynchronous
Input
Control Signal Input. Used to enable or disable the internal
flywheel. When FW_EN/DIS is high, the internal flywheel is
enabled. When FW_EN/DIS is low, the internal fly-wheel is
disabled.
8
CODE_PROTECT
Nonsynchronous
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-ofrange 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
BP_FR
Nonsynchronous
Input
Control Signal Input. Used to enable or disable word
boundary framing. When BP_FR is low internal framing is
enabled. When BP_FR is high internal framing is bypassed.
10
BP_DSC
Nonsynchronous
Input
Control Signal Input. Used to enable or disable the SMPTE
292M descrambler. When BP_DSC is low, the internal SMPTE
292M descrambler is enabled. When BP_DSC is high, the
internal SMPTE 292M de-scrambler is bypassed.
11
WB_NI
Nonsynchronous
Input
Control Signal Input. Used to enable or disable noise immune
operation of the word boundary framer. When WB_NI is high,
noise-immune word boundary alignment is enabled. The
device switches to a new word boundary only when it has
detected two consecutive identical new TRS positions. When
WB_NI is low, the device re-aligns the word boundary position
at every instance of a TRS.
12
TRS_Y/C
Nonsynchronous
Input
Control Signal Input. Used to control whether LUMA or
CHROMA TRS IDs are detected and used. When TRS_Y/C is
high, the device detects and uses TRS signals embedded in
the LUMA channel. When TRS_Y/C is low, the device detects
and uses TRS signals embedded in the CHROMA channel.

DESCRIPTION

TRS_INS
Nonsynchronous
Input
Control Signal Input. Used to enable or disable re-insertion of
the TRS into the data stream. When TRS_INS is high, the
device re-inserts TRS into the incoming data stream based on
the internal calculation. The original TRS packets are set to the
blanking levels. If the flywheel is enabled, TRS calculated by
the flywheel is used for insertion. When TRS_INS is low, the
device will not re-insert TRS even if errors in TRS signals are
detected.
15
LN_INS
Nonsynchronous
Input
Control Signal Input. Used to enable or disable re-insertion of
the line number into the data stream. When LN_INS is high, the
device re-inserts the line number into the incoming data
stream based on the internal calculation. The original line
number packets are set to the blanking levels. If the flywheel is
enabled, the line number calculated by the flywheel is used for
insertion. When LN_INS is low, the device will not re-insert the
line number.
16
CRC_INS
Nonsynchronous
Input
Control Signal Input. Used to enable or disable re-insertion of
the CRC into the data stream. When CRC_INS is high, the
device is enabled to re-insert line CRCs based on the internal
calculation. When CRC_INS is low, the device will not re-insert
the CRCs.
17
FAST_LOCK
Synchronous
wrt PCLK_IN
Input
Control Signal Input. Used to control the flywheel
synchronization when a switch line occurs. When a low to high
transition occurs on the FAST_LOCK signal, the internal
flywheel will immediately re-synchronize to the next valid EAV
or SAV TRS in the incoming data stream. See Fig. 5 for timing
information.
18
RESET
Nonsynchronous
Input
Control Signal Input. Used to reset the system state registers to
their default 720p parameters. When RESET is high, the fly
wheel, TRS Detection, and ANC Detection operate normally.
When RESET is low, the flywheel, TRS Detection, and ANC
Detection are reset to the 720p parameters after a rising edge
on PCLK_IN. The read and write counters are not affected.

flywheel indicates mismatching line numbers. Refer to Fig. 3
for timing information of LN_ERR relative to LUMA

LN_ERR depends on the sequence of line numbers, a line
number error will actually cause LN_ERR to go high for two

5. AUTOMATIC SWITCH LINE LOCK HANDLING
The flywheel logic will check the incoming video data for
valid video lines. If the incoming data represents a valid
line, the flywheel remains in sync with the incoming data. If
the incoming data represents an invalid line, the flywheel
will use the stored timing information for the past valid line
to generate the output HVF timing signals until three (3)
consecutive lines having identical timing are detected. In
this case, the new timing information will be saved and the
flywheel operation is updated to this new timing.
Mismatches between the HVF information decoded from
the data stream and that indicated by the flywheel will
trigger the EAV_ERR and SAV_ERR signals as shown in
Figure 3. HVF output timing is shown in Figure 2.
The automatic switch line lock is based on the assumption
that the switching of video sources will only cause the H
signal to be out of alignment whereas V and F signals
remain in sync; i.e. switching between video sources of the
same format. Therefore, when in the automatic switch line
lock mode (FAST_LOCK transitions for low to high), the
flywheel positive H signal transition will align with the
detected positive H signal transition. Timing for the
FAST_LOCK signal is shown in Figure 5.
