PRELIMINARY DATA SHEET
DESCRIPTION
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.
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.

DESCRIPTION
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.
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.
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.
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.
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.
Output
Control Signal Input. This signal indicates the Horizontal
blanking period of the video signal. Refer to Fig. 2 for timing
information of H relative to DATA_OUT[19:10] and
DATA_OUT[9:0], LUMA and CHROMA respectively.
Output
Control Signal Input. This signal indicates the Vertical blanking
period of the video signal. Refer to Fig. 2 for timing information
of V relative to DATA_OUT[19:10] and DATA_OUT[9:0], LUMA
and CHROMA respectively.
Output
Control Signal Input. This signal indicates the ODD/EVEN field
of the video signal. Refer to Fig. 2 for timing information of F
relative to DATA_OUT[19:10] and DATA_OUT[9:0], LUMA and
CHROMA respectively. When locked and the input signal is of
a progressive scan nature, F stays low at all times.
N/A No Connect. Do not connect these pins.

Output
Control Signal Output. VD_STD[3:0] indicates which input
video standard the device has detected. The GS1510 will
indicate all of the formats in SMPTE292M (see Table 1) plus it
will indicate an unknown interlace or progressive scan format.
