Device Operation
The LMH0041 deserializer is used in digital video signal orig-
ination equipment. It is intended to be operated in conjunction
with an FPGA host which processes the received data to re-
cover the original parallel data from the five bit wide datapath
that comes from the LMH0041. The LMH0041 requires the
use of an external equalizer such as the LMH0044, which can
be directly connected to the LMH0041.
DVB-ASI Mode
DVB-ASI mode is enabled when the DVB-ASI pin is brought
to a high state. When the DVB-ASI mode is enabled, an in-

ternal framer and 8b10b decoder is engaged such that the
data appearing on RX0-RX3 will represent a nibble of the de-
coded 8b10b data. RX4 is an Idle character detect and can
be used as an enable to allow the receiver to not write data
into a FIFO. RX4 is high if the data being presented on
RX0-RX3 represents the idle character. The Most Significant
Nibble of data is presented on the rising edge of RXCLK, and
the lease significant on the falling edge of RXCLK.
