ARC-22x - 250 MHz Fiber Optic Timing Board
The ARC-22x 250 MHz fiber optic timing board performs three main functions - communicating between the controller and the host computer, generating timing waveforms and providing overall controller supervision. It has a duplex fiber optic link to a PCI or PCIe interface board, the ARC-64, ARC-66 or ARC-66x, that operates at a bit rate of 250 MHz, providing a sustained maximum image data transfer rate of 12.5 Mpixels per second. It controls the timing of the analog portions of the controller by writing 16-bit digital words as often as every 40 nanoseconds over a backplane to other controller boards. It performs such supervisory functions as exposure timing, power sequencing, controlling a shutter, and synchronizing operations with signals external to the controller using the Motorola DSP56003 Digital Signal Processor, operating at an internal clock speed of 100 MHz. The ARC-22x is a replacement for the ARC-22 in substituting the obsolete transmitter/receiver pairs with a currently available transceiver mounted in a small metal cage, along with a fiber optic patch cable between ST and LC connectors. The ARC-22x can communicate with the ARC-64, ARC-66 or ARC-66x.
