LMH0341, LMH0041, LMH0071, LMH0051 DVB-ASI Deserializer with Loopthrough LVDS Interface
General Description
LMH0041 family products provide very simple deserializer receiver function. device intended paired with FPGA host which will receive data words will decode data appropriately such that SMPTE standard signal recovered. devices designed receive data compliant with DVB-ASI, SMPTE 259M, SMPTE 292M and/or SMPTE 424M. interface between LMH0041 FPGA consists wide LVDS bus, LVDS clock SMBus interface. devices except LMH0051 includes reclocked feedthrough output with SMPTE compliant cable driver. LMH0341 includes support SMPTE424M, LMH0071 Stadard Definition (SD) only variant. product packaged physically small package.

Device Operation
LMH0041 deserializer used digital video signal origination equipment. intended operated conjunction with FPGA host which processes received data recover original parallel data from five wide datapath that comes from LMH0041. LMH0041 requires external equalizer such LMH0044, which directly connected LMH0041.
ternal framer 8b10b decoder engaged such that data appearing RX0-RX3 will represent nibble decoded 8b10b data. Idle character detect used enable allow receiver write data into FIFO. high data being presented RX0-RX3 represents idle character. Most Significant Nibble data presented rising edge RXCLK, lease significant falling edge RXCLK.
