GENERAL DESCRIPTION
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
AD9396 also offers full sync processing for composite sync and
sync-on-green (SOG) applications.
The AD9396 offers designers the flexibility of an analog
interface and digital visual interface (DVI) receiver integrated
on a single chip. Also included is support for high bandwidth
digital content protection (HDCP).
The AD9396 contains a DVI-compatible receiver and supports
all HDTV formats (up to 1080p and 720p) and display
resolutions up to SXGA (1280 × 1024 @ 80 Hz). The receiver
features an intrapair skew tolerance of up to one full clock cycle.
With the inclusion of HDCP, displays may now receive
encrypted video content. The AD9396 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 1.1 protocol.
The AD9396 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 720p) and FPD resolutions up
to SXGA (1280 × 1024 @ 80 Hz).
The analog interface includes a 150 MHz triple ADC with
internal 1.25 V reference, a phase-locked loop (PLL), program-
mable gain, offset, and clamp control. The user provides only
1.8 V and 3.3 V power supply, analog input, and HSYNC.
Three-state CMOS outputs may be powered from 1.8 V to 3.3V.
The on-chip PLL generates a pixel clock from HSYNC. Pixel
Fabricated in an advanced CMOS process, the AD9396 is pro-
vided in a space-saving, 100-lead, surface-mount, Pb-free plastic
LQFP and is specified over the 0ºC to 70ºC temperature range.
