Description
I- and Q-channel Digital Data Outputs. In Non-
Demux Mode, this LVDS data is transmitted at
the sampling clock rate. In Demux Mode, these
outputs provide ½ the data at ½ the sampling
clock rate, synchronized with the delayed data,
i.e. the other ½ of the data which was sampled
one clock cycle earlier. Compared with the DId
and DQd outputs, these outputs represent the
later time samples. If used, each of these outputs
should always be terminated with a 100Ω
differential resistor placed as closely as possible
to the differential receiver.
Delayed I- and Q-channel Digital Data Outputs.
In Non-Demux Mode, these outputs are tri-
stated. In Demux Mode, these outputs provide ½
the data at ½ the sampling clock rate,
synchronized with the non-delayed data, i.e. the
other ½ of the data which was sampled one clock
cycle later. Compared with the DI and DQ
outputs, these outputs represent the earlier time
samples. If used, each of these outputs should
always be terminated with a 100Ω differential
resistor placed as closely as possible to the
differential receiver.
