Notes:
1. The Line Numbers in brackets refer to version zero SMPTE ST 352 packet locations, if they are different from version 1.
2. The part may provide full or limited functionality with standards that are not included in this table. Please consult a Semtech technical
representative.
By default (at power up or after system reset), the four RASTER_STRUC_X, STD_LOCK
and INT/PROG registers are set to zero. These registers are also cleared when the
SMPTE_BYPASS pin is LOW, or the LOCKED pin is LOW.
Note 1: The Line Numbers in brackets refer to Version zero SMPTE ST 352 packet
locations, if they are different from the Version one locations.
Note 2: 3G formats cannot be fully determined from these measurements. Their
detailed information will be derived from SMPTE ST 352 packets, which must be in the
video stream as a mandatory requirement of the SMPTE ST 424 specification, as
described below.
