1. DESCRIPTION OF THE ADV7281-M EVALUATION BOARD
Analog video is fed into the analog inputs (Ain1 to Ain6) of the ADV7281-M evaluation board. The ADV7281-M evaluation board can be
configured to receive many different analog video formats (refer to
Table 1 ). The analog video from analog inputs is fed into the
ADV7281-M video decoder which converts it into a MIPI CSI-2 output stream.
The MIPI CSI-2 output of the ADV7281-M consists of one differential data lane (D0+ and D0-) and one differential clock lane (Clk+ and
CLk-). These are output to the SMA connectors on the evaluation board.

Note
: The shaded areas in Table 1 indicate that modifications need to be made to the ADV7281-M evaluation board before that particular
video input standard can be input to that particular analog input pin.
[1] These inputs can be configured to receive single-ended CVBS, but the user needs to change some resistor values on the ADV7281-M
evaluation board.
[2] Ain1 and Ain2 can be configured to receive differential CVBS, but the user needs to change some resistor values on the ADV7281-M
evaluation board.
[3] These inputs can be configured to receive YC (S-video), but the user needs to change some resistor values on the ADV7281-M
evaluation board.
[4] These inputs can be configured to receive component (YPbPr), but the user needs to change some resistor values on the ADV7281-M
evaluation board.
