• Manufacturer Part Number: GS1560A
• Description: Reclocking Deserializer For HD-SDI, Sd-sdi & Dvb-asi With Loop Thru Cable Driver. 3.3/1.8V Supply.
• Manufacturer: Gennum Corporation

3.10.6.5 HD Line Number Error Correction
In HD mode, the GS1560A will calculate and insert line
numbers into the Y and C channels of the output data
stream.
Line number generation is in accordance with the relevant
HD video standard as determined by the device, (see
section 3.10.4).
This feature is enabled when SD/HD = LOW, and the
LNUM_INS bit of the IOPROC_DISABLE register is set LOW.
3.10.6.6 TRS Error Correction
When TRS error correction and insertion is enabled, the
GS1560A will generate and insert 10-bit TRS code words as
required.
TRS word generation will be performed in accordance with
the timing parameters generated by the flywheel to provide
an element of noise immunity. As a result, TRS correction

will only take place if the flywheel is enabled, (FW_EN/DIS =
HIGH).
In addition, the TRS_INS bit of the IOPROC_DISABLE
register must be set LOW.
3.10.7 EDH Flag Detection
As described in section 3.10.5.2, the GS1560A can detect
EDH packets in the received data stream. The EDH flags for
ancillary data, active picture and full field areas are
extracted from the detected EDH packets and placed in the
EDH_FLAG register of the device (Table 15).
One set of flags is provided for both fields 1 and 2. Field 1
flag data will be overwritten by field 2 flag data.
NOTE: The GS1560A will detect EDH flags, but will not
update the flags if an EDH CRC error is detected.
Gennum's GS1532 Multi-Rate Serializer allows the host to
individually set EDH flags.
