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.

1 The minimum/maximum specifications are guaranteed over the −40°C to +85°C temperature range (TMIN to TMAX).
2 All ADC linearity tests were performed at input range full scale − 12.5% and at zero scale + 12.5%.
3 Pin 1, Pin 105, Pin 106, and Pin 144 are 5 V tolerant.
4 Guaranteed by characterization.
5 The VOH and VOL levels were obtained using the default drive strength value (0x15) in User Map Register 0xF4.
6 Current measurements for analog inputs were made with HDMI/analog simultaneous mode disabled (User Map Register 0xBA, Bit 7, programmed with Value 0) and
with no HDMI sources connected to the part.
7 Typical current measurements were taken with nominal voltage supply levels and an SMPTE bar video pattern input. Maximum current measurements were taken
with maximum rating voltage supply levels and a MoiréX video pattern input.
8 Current measurements for HDMI inputs were made with a source connected to the active HDMI port and with no source connected to the inactive HDMI port.
9 Audio stream is an uncompressed stereo audio sampling frequency of fS = 48 kHz, and MCLKOUT = 256 fS.
10 The maximum IDVDDIO value for the HDMI RGB sampling @ 225 MHz appears lower than expected. This is due to the 1080p 12-bit deep color mode input used during
evaluation. In this mode, the input HDMI TMDS clock has a frequency of 222.75 MHz; however, the output pixel clock is stepped down to 148.5 MHz to account for the
extra bits of data. DVDDIO power is proportional to the output pixel clock, therefore the stepping down of the output pixel clock data in 1080p 12-bit deep color
mode results in lower than expected IDVDDIO.
11 Analog current measurements for CVBS were made with only ADC0 powered up; for RGB, with only ADC0, ADC1, and ADC2 powered up; for SCART FB, with all ADCs
powered up; and for HDMI mode, with all ADCs powered off.
12 The terminator supply current may vary with the HDMI source in use.
