AD9380: Analog/HDMI Dual-Display Interface
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.
Pixel clock output frequencies range from 12 MHz to 150 MHz. PLL clock jitter is typically less than 700 ps p-p at 150 MHz. The AD9380 also offers full sync processing for composite sync and sync-on-green (SOG) applications.
The AD9380 contains an HDMI 1.1-compatible receiver and supports all HDTV formats (up to 1080p and 720p) and display resolutions up to SXGA (1280 × 1024 @ 75 Hz). The receiver features an intrapair skew tolerance of up to one full clock cycle. With the inclusion of HDCP, displays can now receive encrypted video content. The AD9380 allows for authentication of a video receiver, decryption of encoded data at the receiver, and renewability of the authentication during transmission, as specified by the HDCP 1.1 protocol.
Fabricated in an advanced CMOS process, the AD9380 is provided in a space-saving, 100-lead, surface-mount, Pb-free plastic LQFP and is specified over the 0°C to 70°C temperature range.
