GENERAL DESCRIPTION
The AD9380 offers designers the flexibility of an analog interface and high definition multimedia interface (HDMI) receiver integrated on a single chip. Also included is support for high bandwidth digital content protection (HDCP).
The AD9380 is a complete 8-bit, 150 MSPS, monolithic analog interface optimized for capturing component video (YPbPr) and RGB graphics signals. Its 150 MSPS encode rate capability and full power analog bandwidth of 330 MHz supports all HDTV formats (up to 1080p and FPD resolutions up to SXGA(1280 × 1024 @ 75 Hz).
The analog interface includes a 150 MHz triple ADC with internal 1.25 V reference, a phase-locked loop (PLL), and programmable gain, offset, and clamp control. The user provides only 1.8 V and 3.3 V power supplies, analog input, and HSYNC..
Three-state CMOS outputs can be powered from 1.8 V to 3.3 V.
An on-chip PLL generates a pixel clock from HSYNC.
