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.

All ADC linearity tests were performed at input range full scale − 12.5% and at zero scale + 12.5%.

Pin 1, Pin 105, Pin 106, and Pin 144 are 5 V tolerant.

Guaranteed by characterization.

The V

and V

levels were obtained using the default drive strength value (0x15) in User Map Register 0xF4.

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.

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.

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.

Audio stream is an uncompressed stereo audio sampling frequency of f

= 48 kHz, and MCLKOUT = 256 f

The maximum I

DVDDIO

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 I

DVDDIO

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.

The terminator supply current may vary with the HDMI source in use.
