The interface schemes for DVB are defined in the European standard EN 50083-9, "Interfaces for CATV/SMATV Headends and Similar ProfessionalEquipment". DVB via Asynchronous Serial Interface (DVB-ASI) is one of the primary mechanisms to transport MPEG-2 based streams over cable media. DVB-ASI is a three-layered architecture with the top layer (Layer 2) specified by IEC 13818-1 and the bottom layers, Layer 1 and Layer 0, specified by the Fibre Channel standard IEC 141165-1, part 1. This IP core along with LatticeECP3TM SERDES/PCS implements Layer 1 of the DVB-ASI interface. A part of Layer 2 functionality is also supported by the IP core. DVB-ASI Interface Layers Key Features Configurable Tx FIFO supporting independent Layer 2 transmit clock Configurable Rx FIFO supporting independent Layer 2 receive clock Automatic start of packet comma insertion in the transmit side Rate-matching comma insertion in the transmit side Handshake signals for sync and data valid for transmitter and receiver Tx and Rx FIFO full indicators Rx sync byte indicator for identifying start-of-packet Optional configurable almost full and almost empty indicators for the FIFOs Matching port names for seamless connection with LatticeECP3 SERDES/PCS Layer 2 functions including lock, sync byte, packet size, runt and giant indicators Performance and Resource Utilization LatticeECP3 1 Sample Configuration SLICEs LUTs Registers EBRs Tx Clk Tx Full Clk Rx Full Clk Rx Clk 1 249 478 343 2 113 119 127 219 2 84 162 136 1 183 121 - - 3 156 301 202 1 - - 117 203 1. Performance and utilization data are generated targeting an LFE3-95E-7FN1156C device with Lattice's Diamond 1.1 software. Performance may vary when using a different software version or targeting a different device density or speed grade within the LatticeECP3 family. http://www.latticesemi.com/products/intellectualproperty/ipcores/dvbasi.cfm 10/11/2011 DVB ASI Page 2 of 2 Ordering Information Family LatticeECP3 Part Number DVB-ASI-E3-U IP Version: 1.1 Evaluate: To download a full evaluation version of this IP, go to the IPexpress tool and click the IP Server button in the toolbar.
