External bias resistor connection. Nominal value is 3.3k-Ohms
(±0.1%) to ground. See Section 1.1.1.
Temperature Diode Positive (Anode) and Negative (Cathode).
These pins may be used for die temperature measurements,
however no specified accuracy is implied or guaranteed. Noise
coupling from adjacent output data signals has been shown to
affect temperature measurements using this feature. See Section
2.6.2.
I and Q channel LVDS Data Outputs that are not delayed in the
output demultiplexer. Compared with the DId and DQd outputs,
these outputs represent the later time samples. These outputs
should always be terminated with a 100Ω differential resistor.
I and Q channel LVDS Data Outputs that are delayed by one CLK
cycle in the output demultiplexer. Compared with the DI/DQ
outputs, these outputs represent the earlier time sample. These
outputs should always be terminated with a 100Ω differential
resistor.
Out Of Range output. A differential high at these pins indicates that
the differential input is out of range (outside the range ±325 mV or
±435 mV as defined by the FSR pin).
Differential Clock outputs used to latch the output data. Delayed
and non-delayed data outputs are supplied synchronous to this
signal. This signal is at 1/2 the input clock rate in SDR mode and
at 1/4 the input clock rate in the DDR mode. The DCLK outputs
are not active during a calibration cycle, therefore this is not
recommended as a system clock.
