General Description
The LMH0040 family of products provide a very simple 5:1
serializer and transmitter function, intended to be paired with
an FPGA host which will format the data appropriately such
that the output of the LMH0040 will be compliant with the out-
put requirements of DVB-ASI, SMPTE 259M, and SMPTE
292M. The LMH0340 adds support for SMPTE 424M, the
LMH0070 supports 270 Mbps operation only, and the
LMH0050 requires an external cable driver. Throughout this
document, if not explicitly stated, when the LMH0040 is re-
ferred to this includes all members of the family. The interface
between the LMH0040 and the FPGA consists of a 5 bit wide
LVDS bus, an LVDS clock and an SMBus interface. The
product is packaged in a physically small 48 pin LLP package.
