7.2.4 DMD Mirror Switching Performance Plots

In these particular applications, the performance plot shown in Figure 7-2 shows the maximum loaded and displayed pixels per second when the valid data pattern time is at the maximum time to still operate at the fastest pattern rate of each MCP mode for the different MCP modes. When the exposure period is increased, the pixels per second decreases.

DLPC964 DLP991U DMD Performance Plot at 3.6Gbps Data Rate Figure 7-2 DLP991U DMD Performance Plot at 3.6Gbps Data Rate.

The following equations describe how to calculate the maximum loaded and displayed pixels per second when the exposure period is set to its minimum for the different reset modes:

Global Block Exposure Period = Number of DMD Blocks Loaded × DMD Block Load Time
Cycle Period = Exposure Period + ((16 ÷ # Blocks Reset) × MCP Active Period) + Mirror Settling Time
Pattern Rate = 1 ÷ Cycle Period
Pixel Data Rate = Pattern Rate × 4096 × 2176

For Global Reset Mode, the calculations are:

Global Block Exposure Period = 16 × 5.04444μs = 80.711μs
Cycle Period = 80.711μs + 4μs + 4μs = 88.711μs
Pattern Rate = 1 ÷ 88.711μs = 11.272kHz
Pixel Data Rate = 11.272kHz × 4096 × 2176 = 100.47Gbps

For Single Block Reset Mode, the calculations are:

Single Block Exposure Period = 11.67μs
Cycle Period = 11.67μs + 64μs + 4μs = 79.67μs
Pattern Rate = 1 ÷ 79.67μs = 12.551kHz
Pixel Data Rate = 12.551kHz × 4096 × 2176 = 111.88Gbps

For Dual Block Reset Mode, the calculations are:

Dual Block Exposure Period = 44.71μs
Cycle Period = 44.71μs + 32μs + 4μs = 80.71μs
Pattern Rate = 1 ÷ 80.71μs = 12.390kHz
Pixel Data Rate = 12.390kHz × 4096 × 2176 = 110.43Gbps

For loading a single DMD row and resetting, the equations and calculations are:

DMD Row Load Time = DMD Block Load Time ÷ Number of Rows in a DMD Block
DMD Row Load Time = 5.04444μs ÷ 136 = 0.03709μs
Exposure Period = 0.03709μs
Cycle Period = 0.03709μs + 4μs + 4μs = 8.03709μs
Pattern Rate = 1 ÷ 8.03709μs = 124.423kHz
Pixel Data Rate = 124.423kHz × 4096 = 509.64Mbps
