TC5747 Preliminary Data Sheet
Single Chip CMOS Imager
Figure 12: PVI YUV Output Format
Figure 13: RGB 565 Output on Parallel Video Output Interface
The output clock rate for YUV or 2-word RGB output is double the output clock rate for Bayer output. The
output clock rate for 3-word RGB666 is double the output clock rate for YUV output.
When sending out the data in Bayer-grid format, a “ RED” line will always be the first line in the frame.
4.2.2 External Chip-Select
A mode may be selected where the data bus may be floated or driven according to an external chip-select
input controlled by the CSDAT# pin. The CSDAT# pin is active-low, i.e. when low the DOUT[9:1] or DYUV[7:0]
bus pins are driven, and when CSDAT# is high these outputs are put in a tri-state position. The VALIDH,
VALIDV and VCLKOUT pins are not affected by the CSDAT# pin.
4.2.3 Qualified Clock Mode
The TC5747 supports a mode where the VCLKOUT pin is not active when there is no active data on the
parallel interface.
