AD9880: Analog/HDMITM Dual Display Interface

The AD9880 offers designers the flexibility of an analog interface and High-Definition Multimedia Interface (HDMITM) receiver integrated on a single chip. Also included is support for High bandwidth Digital Content Protection (HDCP).

Analog Interface

The AD9880 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 300 MHz supports all HDTV formats (up to 1080p) and FPD resolutions up to SXGA (1280 x 1024 at 75 Hz).

The analog interface includes a 150 MHz triple ADC with internal 1.25V reference, a Phase Locked Loop (PLL), and programmable gain, offset, and clamp control. The user provides only 1.8V and 3.3V power supply, analog input, and Hsync. Three-state CMOS outputs may be powered from 1.8V to 3.3V. The AD9880’s 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 500 ps p-p at 150 MHz. The AD9880 also offers full sync processing for composite sync and Sync-on-Green (SOG) applications.

Digital Interface

The AD9880 contains a HDMI v1.1 compatible receiver and supports all HDTV formats (up to 1080p) and display resolutions up to SXGA (1280 x 1024 at 75 Hz). The receiver features an intra-pair skew tolerance of up to one full clock cycle. With the inclusion of HDCP, displays may now receive encrypted video content. The AD9880 allows for authentication of a video receiver, decryption of encoded data at the receiver, and renewability of that authentication during transmission as specified by the HDCP v1.1 protocol.

Fabricated in an advanced CMOS process, the AD9880 is provided in a space-saving 100-lead LQFP surface-mount Pb-free plastic package and is specified over the 0 oC to 70 oC temperature range.
