Laser Driver for Projectors
MAX3600
20
Configuration 1: RGB Laser Driver
with DDR Clock
Configuration 1 is described in Figures 19 and 20 and
Table 12.
• 10-bit video (D0 = LSB, D9 = MSB), DDR clock
• Data is multiplexed R-G-B (Figure 20)
• SYNC = 1 when blue data is on D0 to D9
• PO event occurs when PO = 1

Note: See the Detailed Description section for more informa-
tion about register programming.
