EVL2510
Evaluation System for AVC2510 Dual-Channel Video
Format Converter

General Description

The EVL2510 is a system that enables evaluation of the key
features of the AVC2510 dual-channel adaptive video con-
verter. The system consists of a 2-channel analog input card
with OSD generator, an HDMI input card, the main AVC2510
card, an output card and an optional CPU card. The system
accepts a wide range of analog inputs including composite
(CVBS), interlaced standard definition component or RGB
(SCART), HD component, VGA as well the digital HDMI
signal. The AVC2510 can take any two input signals, treating
one as the primary channel and the other as the secondary
PIP channel, merge them in PIP, PAP or POP formats, and
then blend the OSD on top using alpha-blending. In the
Primary channel, 3D noise reduction and deinterlacing are
performed, followed by high order scaling. In the Secondary
PIP channel the processing is in 2D, with similar functional-
ity. Three types of output signals are supported: The Primary
Output provides High Definition RGB/YPbPr (analog) and
HDMI (480p, 576p, 720p, 1080i or 1080p/60) from any input
source, up or down-converted. The Secondary output pro-
vides a simultaneous (CVBS and component) down-
converted version of the same signal being output on the
Primary channel.

LIFE SUPPORT POLICY

NATIONAL'S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS
WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR
CORPORATION. As used herein:

1. Life support devices or systems are devices or systems

which, (a) are intended for surgical implant into the body, or
(b) support or sustain life, and whose failure to perform when
properly used in accordance with instructions for use
provided in the labeling, can be reasonably expected to result
in a significant injury to the user.

2. A critical component is any component of a life support

device or system whose failure to perform can be reasonably
expected to cause the failure of the life support device or
system, or to affect its safety or effectiveness.
