(1) When measured on a system, typical PVT (process, voltage, and temperature) conditions (for example, nominal process, typical voltage, and 25°C nominal ambient temperature) and various input images were used.
(2) Measured on a system with worst case PVT condition(s) (i.e. corner process, high voltage, and high temperature of 65°C) and white noise input image.
(3) This rail was not measured due to board limitations. Simulation values are used instead. Simulations assume 12.5% activity factor, 30% clock gating on appropriate domains, and mixed SVT (standard threshold voltage) or HVT (high threshold voltage) cells.
(4) For the measured cases, all pins using 1.1 V were tied together (including VDDLP12), and programmable host and flash I/O are at the minimum nominal voltage (that is 1.8 V).
(5) Input image is 854 × 480 (WVGA) 24-bits using reduced VESA timings on the parallel interface at the frame rate shown with the 0.2-inch WVGA (DLP2010LC) DMD. The controller has the CAIC and LABB algorithms turned off.
(6) The measured values do not take into account software updates or customer changes that may affect power performance.
(7) The reported numbers are valid only when operating the DLPC3470 in display mode.
