NOTES:
1. The Line Numbers in brackets refer to version zero SMPTE 352M 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.
3. For SD-SDI streams, the device can report an incorrect M value when SMPTE-352M packets are present.
NOTE: In certain systems, due to greater ppm offsets in the crystal, the ‘M’ bit may not
assert properly. In such cases, bits 3:0 in Register 06Fh can be increased to a maximum
value of 4.
By default (after power up or after systems reset), the four RASTER_STRUCTURE,
VD_STD, STD_LOCK and INT/PROG registers are set to zero. These registers are also
cleared when the SMPTE_BYPASS pin is LOW.
