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.

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.
