APPLICATIONS

GENERAL DESCRIPTION

The AD9880 offers designers the flexibility of an analog interface

and high definition multimedia interface (HDMI) receiver inte-

grated on a single chip. Also included is support for high band-

width digital content protection (HDCP).

Analog Interface

The AD9880 is a complete 8-bit 150 MSPS monolithic analog inter-

face 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

1080 p) 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. 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 700 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 1.1-compatible receiver and sup-

ports all HDTV formats (up to 1080 p and 720 p) 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 AD9880 allows for authentication of a video

receiver, decryption of encoded data at the receiver, and renewa-

bility of the authentication during transmission, as specified by the

HDCP v 1.1 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°C to 70°C temperature range.
