ADV7850KBCZ-5 Datasheet, PDF (27/32 Pages) Analog Devices – Complete AV Front End

Data Sheet
VBI DATA PROCESSOR (VDP)
VBI extraction of Teletext, CC, WSS, CGMS, PDC, UTC, VPS,
GEMSTAR, and VITC data is performed by the VBI data
processor of the ADV7850 at interlaced, progressive, and high
definition scanning rates. The data extracted can be read back
over the SPI interface.
TMDS OUTPUT
The ADV7850 incorporates a 297 MHz TMDS output. This
interface is designed to connect to any internal IC with an HDMI
or DVI input port.
The digital video interface contains an HDMI and a DVI 1.0-
compatible transmitter, and supports all HDTV formats up to 3D
1080p at 60 Hz and 2160p at 24 Hz. The ADV7850 transmitter
fully supports programmable AVI InfoFrames. With the inclusion
of HDCP, the ADV7850 transmitter allows the secure transmission
of protected content as specified by the HDCP protocol. The
ADV7850 transmitter also fully supports EDID read operations.
The ADV7850 TMDS output supports the audio mode received
from the HDMI receiver, that is, PCM, HBR, DSD, and DST.
EXTERNAL MEMORY REQUIREMENTS
The ADV7850 requires an external SDRAM for 3D comb and
frame TBC. The ADV7850 supports DDR2 memories.
ADV7850
Double Data Rate 2 (DDR2)
The ADV7850 can use DDR2 external memory to simultane-
ously provide 3D comb and frame TBC operation.
It requires a minimum memory of 128 Mb with a speed grade of
200 MHz at CAS latency (CL) 3.
The recommended DDR2 memory compatible with the
ADV7850 include the MT47H32M16HR-25E:G from Micron
Technology, Inc.
OTHER FEATURES
The ADV7850 has one I²C host port interface.
The ADV7850 has two programmable interrupt request output
pins, INT1 and INT2. It also features a number of low power
modes and a full power-down mode. The ADV7850 contains an
internal power regulator to accommodate power-off mode. In
this mode, the ADV7850 is powered from the 5 V supply of the
HDMI/VGA cable connected to a source device or devices. In
this mode, EDID can be read over an HDMI/VGA DDC link.
The ADV7850 is provided in a 19 mm × 19 mm, RoHS-compliant
CSP_BGA package and is specified over the −20°C to +70°C
temperature range.
