Performance The video timing parameters supported by the Matrox Meteor-II /Camera Link
board are as follows:
Video data input
The video and the synchronization signals, up to 28 bits (24 bits of video data
and 4 bits of syncs), are transmitted as serialized data from the camera to the frame
grabber over four LVDS pairs, along with a clock on a fifth LVDS pair.
Communication
Two LVDS pairs are used to transmit or receive asynchronous serial
communication between the camera and the frame grabber. These signals are
handled by the Universal Asynchronous Receiver/Transmitter (UART).
UART
Matrox Meteor-II /Camera Link features a Universal Asynchronous
Receiver/Transmitter (UART) that provides a serial interface. For example, this
allows you to remotely control a camera or a motion control unit, or to
communicate with a program logic controller (PLC). The UART is programmed
using the MIL-Lite function, MdigControl() with the M_UART... control types.
Lookup tables
The Matrox Meteor-II /Camera Link board has four 8K x 8-bit programmable
lookup tables. The LUTs on Matrox Meteor-II /Camera Link can be operated as
four 8-bit lookup tables, two 10-bit lookup tables, or two 12-bit lookup tables.
PSG
The Programmable Synchronization Generator (PSG) is responsible for managing
all video timing and synchronization signals.
Control signals
The following is a short description of the control signals featured on the board.
Most signals are in LVDS format. It is indicated when a signal is in a format other
than LVDS, such as TTL.
Max
Number of pixels / line (including sync and blanking) 65536
Number of lines / frame (including sync and blanking) 65536
Sampling rate 50 MHz
