APPLICATIONS Advanced TV CMOS outputs can be powered from 1.8 V to 3.3 V. The HDTV AD9880s on-chip PLL generates a pixel clock from Hsync. Pixel Projectors clock output frequencies range from 12 MHz to 150 MHz. PLL LCD monitor clock jitter is typically less than 700 ps p-p at 150 MHz. The AD9880 also offers full sync processing for composite sync and GENERAL DESCRIPTION sync-on-green (SOG) applications. The AD9880 offers designers the flexibility of an analog interface Digital Interface and high definition multimedia interface (HDMI) receiver inte- The AD9880 contains a HDMI 1.1-compatible receiver and sup- grated on a single chip.

The receiver Analog Interface features an intrapair skew tolerance of up to one full clock cycle. The AD9880 is a complete 8-bit 150 MSPS monolithic analog inter- With the inclusion of HDCP, displays can now receive encrypted face optimized for capturing component video (YPbPr) and RGB video content. The AD9880 allows for authentication of a video graphics signals.

HDCP v 1.1 protocol. The analog interface includes a 150 MHz triple ADC with internal Fabricated in an advanced CMOS process, the AD9880 is provided 1.25 V reference, a phase-locked loop (PLL), and programmable in a space-saving, 100-lead LQFP surface-mount Pb-free plastic gain, offset, and clamp control. The user provides only 1.8 V and package and is specified over the 0C to 70C temperature range. 3.3 V power supplies, analog input, and Hsync.
