SOURCE DATA PORTS

SuperCONAN® handles multiple synchronous source data channels from 1.4 Mbps up to a maximum of 10.75Mbps for the transfer of audio and video data encoded video data. All data ports share a common frame synchronization and serial bit clock. Data can be arranged as Philips I2S, Sony or Matsushita, 16 or 24 bit serial formats. Additionally, SR0/SX0 can be configured for operation as an IEC-958 (SPDIF) serial interface.

PARALLEL INTERFACE

The 8 bit wide parallel interface for source and control data incorporates two 28 byte buffers, which perform rate conversion between data from the network and data from the application. One buffer handles data from the network, whilst the other handles data from the application. After each frame, the buffers swap over, allowing current data to be read by the application or transmitted on the network and new data to be loaded. The parallel interface (PI) supports synchronous and asynchronous data rates of 10.36Mbit/s. It can be driven on an interrupt or polled basis, or via DMA data transfer. The DMA transfer is compatible with industry standard microprocessors and DMA controllers such as Intel 8237A, Hitachi SH7604. The PI provides three DMA channels with the ability to read and write with each channel concurrently without reconfiguring the DMA controller and supports single, block and demand DMA modes controller operation.
