Additional Features
There are two variants of the CX25858 offered — one with the
external DDR2 interface, and one without the interface. When
equipped with DDR2, the CX25858 supports frame-interleaved
video outputs, as well as a 2x2 CIF tiling mode, in which four CIF
images are tiled into a single D1 stream.
The CX25858 may be cascaded with the CX25838 to create a
16-channel system for sending video and audio data over PCIe.
The CX25858 includes programmable motion detection logic,
which can trigger flags or PCIe interrupts when motion is detected
on incoming analog video streams.
The CX25858 contains 48 GPIO pins, which maximize flexibility
and allow customization to a variety of applications and designs.
I2C interfaces and the Maxim interface are supported via GPIOs.
