P2042A Datasheet | Alliance Semiconductor

August 2005 rev 1.3 LCD Panel EMI Reduction IC Features - - - - - - - - - - - - .. P2042A wide reduction of EMI of down stream clock and data FCC approved method of EMI attenuation. Provides up to 15dB of EMI suppression. Generates a low EMI spread spectrum clock of the input frequency. Input frequency range: 30MHz to 110MHz. Optimized for 32.5MHz, 54MHz, 65MHz and 108MHz pixel clock frequencies. Internal loop filter minimizes external ponents and board space. Eight selectable high spread ranges up to ± 1.9%. SSON# control pin for spread spectrum enable and disable options. Low cycle-to-cycle jitter. 3.3V ± 0.3V operating range. Low power CMOS design. Supports most...
