The Conexant CX25858 8-input Audio/8-input Video
Digitizer is PCIe-based and supports simultaneous digitizing of
up to 8 each audio and NTSC/PAL video inputs. The CX25858
contains 8 high quality video decoders with 10-bit A/ADCs and
5-line comb filtering.
As normally configured on the AgatePXC/2, 2 stereo pairs and
8 video inputs are available on the front panel. Each video input
can be independently scaled and includes per-channel pro-
grammable motion detection.

A high performance USB 3.0-based Cypress CX3 peripheral
controller supports a MIPI CSI-2 camera port with up to 4 input
lanes. Access is limited to the front panel.
An adapter boardlet (page 9) enables easy connection to an
Avnet WandCam OV5640 high-resolution camera and the Agate
50-pin I/O breakout cable via a 33-pin 0.5mm FPC connector.

An Analog Devices ADV7441A High Speed RGB/DVI
Digitizer is linked to a Cypress FX3 Cypress FX3 USB 3.0
peripheral controller.
The RGBHV can be accessed at both the front and rear panel.
The DVI is only available at the rear panel.
The 8-bit portion of the FX3 YUV port can be accessed directly,
bypassing the ADV7441A. This can be used to enable connec-
tion to an OV5640 high-resolution camera. An adapter boardlet
(page 9) enables easy connection to the Agate via a 24-pin
0.5mm FPC connector.

As shown in Table 3, below, the AgatePXC/2 provides six
different input functions. Of those six, you can use only
one out of DVI, RGBHV, or YUV at a given time because
they share the same data path.
Since the CX25858, FX3, and CX3 can run simultaneous-
ly, you MUST have at least a 64/66 PCI/PMC or x4 PCIe
host to attain optimal performance levels. The CX2585
won’t even run on 32/33 PCI.
By default, 2 stereo pairs are provided on the SDR50 con-
nector. By special order, an additional 2 pairs can be had
in place of the multi-mode analog output.
