(1) All parameters in this row follow the BT.656 standard. The image format is always landscape.
(2) The user must stay within specifications for all source interface parameters such as max clock rate and max line rate.
(3) The max DMD size for all rows in the table is 1280 × 720.
(4) To achieve the ranges stated, the composer-created firmware used must be defined to support the source parameters used.
(5) These interfaces are supported with the DMD sequencer sync mode command (3Bh) set to auto.
(6) Bits / Pixel does not necessarily equal the number of data pins used on the DLPC3478. Fewer pins are used if multiple clocks are used per pixel transfer.
(7) BT.656 uses 16-bit 4:2:2 YCr/Cb.
(8) By using an I2C command, portrait image inputs can be rotated on the DMD by minus 90 degrees so that the image is displayed in landscape format.
