GENERAL DESCRIPTION
The ADV7441A is a high quality multiformat video decoder and
graphics digitizer with an integrated 2:1 multiplexed HDMI receiver.
The ADV7441A contains two main processing sections. The
first section is the standard definition processor (SDP), which
processes all types of PAL, NTSC, and SECAM signals. The second
section is the component processor (CP), which processes YPrPb
and RGB component formats, including RGB graphics. The
CP also processes the video signals from the HDMI receiver. The
ADV7441A can keep the HDCP link between a HDMI source
and the selected HDMI port active in analog mode operation. This
allows for fast switching between the analog and HDMI modes.
As a decoder, the ADV7441A can convert PAL, NTSC, and
SECAM composite or S-Video signals into a digital ITU-R
BT.656 format. It can also decode a component RGB or YPrPb
video signal into a digital YCrCb or RGB pixel output stream.
The ADV7441A supports the 525i, 625i, 525p, 625p, 720p, 1080i,
1080p, and 1250i component video standards, as well as many
other HD and SMPTE standards. SCART and overlay functionality
are enabled by the ability of the ADV7441A to process CVBS
and standard definition RGB signals simultaneously. As a
graphics digitizer, the ADV7441A can digitize RGB graphics
signals from VGA to UXGA rates and convert them to a digital
RGB or YCrCb pixel output stream.
The ADV7441A incorporates a dual-input HDMI-compatible
receiver that supports HDTV formats up to 1080p and display
resolutions up to UXGA. The reception of encrypted video is
possible with the inclusion of HDCP. The inclusion of adaptive
equalization in the HDMI receiver ensures robust operation of the
interface with cable lengths up to 30 meters. The HDMI receiver
has advanced audio functionality, including a mute controller
that prevents audible extraneous noise in the audio output.
To facilitate professional applications, where HDCP processing
and decryption is not required, a derivative part of the ADV7441A
is available. This allows users who are not HDCP adopters to pur-
chase the ADV7441A (see the Ordering Guide section for details).
Fabricated using an advanced CMOS process, the ADV7441A
is available in a space-saving, 144-lead, surface-mount, RoHS-
compliant, plastic LQFP and is specified over the −40°C to
+85°C temperature range.

Data Sheet
PACKAGE THERMAL PERFORMANCE
To reduce power consumption during ADV7441A operation,
turn off unused ADCs.
On a 4-layer PCB that includes a solid ground plane, the value
of θJA is 25.3°C/W. However, due to variations within the PCB
metal and, therefore, variations in PCB heat conductivity, the
value of θJA may differ for various PCBs.
The most efficient measurement technique is to use the surface
temperature of the package to estimate the die temperature
because it is not affected by the variance associated with the
value of θJA.
The maximum junction temperature (TJ_MAX) of 119°C must not
be exceeded. The following equation calculates the junction
temperature using the measured surface temperature of the
package and applies only when no heat sink is used on the
device under test:
TJ_MAX = TS + (ΨJT × WTOTAL)
where:
TS is the surface temperature of the package expressed in degrees
Celsius.
ΨJT is the junction-to-package surface thermal resistance.
WTOTAL = {(AVDD × IAVDD) + (DVDD × IDVDD) + (DVDDIO ×
IDVDDIO) + (PVDD × IPVDD) + (CVDD × ICVDD) + (TVDD × ITVDD)}.
The ADV7441A can be operated in ambient temperatures of
up to +85°C. However, in video modes where highest power
is consumed and there is higher than nominal power supply
voltages and worst-case video data, operation at these ambient
temperatures may cause the junction temperature to exceed its
maximum allowed value (119°C). One way to avoid this is to
restrict the ambient temperature to be below +79°C. However, even
if the ambient temperature is kept below +79°C, the user still needs
to observe the thermally efficient PCB design recommendations
outlined in this section to ensure that the maximum allowed
junction temperature is not exceeded in any video mode.
Contact an Analog Devices, Inc., sales representative or a field
applications engineer (FAE) for more information on package
thermal performance.
