5.12.9.1.2.2 DSS—Parallel Interface—RFBI Mode—Pico DLP

The Remote Frame Buffer Interface (RFBI) module can provide also the necessary control signals and data to interface to the Pico DLP driver of the Pico DLP panel. Table 5-77 assumes testing over the recommended operating conditions and electrical characteristic conditions below (see Figure 5-98).

  1. See DM Operating Condition Addendum for OPP voltages.
  2. At OPP100, L4 clock is 100 MHz and at OPP50, L4 clock is 50 MHz.
  3. rfbi_wr must be at 25 MHz.
  4. A = (WECycleTime – WEOffTime) × (TimeParaGranularity + 1) × L4CLK
  5. B = (WEOffTime – WEOntime) × (TimeParaGranularity + 1) × L4CLK
  6. C = WEOnTime × (TimeParaGranularity + 1) × L4CLK
  7. D = (WECycleTime + CSPulseWidth – WEOffTime) × (TimeParaGranularity + 1) × L4CLK if mode Write to Read or Read to Write is enabled.
  8. In rfbi_csx, x is equal to 0 or 1.
