Circuit Description (continued)
Delay Dispersion
Given a constant temperature and voltage environment
(within the bounds of the recommended operating
conditions), the propagation delay dispersion (TSD)
indicates how much variation in propagation delay time
can be expected for one comparator over a wide range
of input conditions. Thus, the propagation delay of a
comparator can be described as:
Tpd
± TSD
where TPD is the nominal delay that will vary with
temperature and voltage, and part to part. In many ATE
applications, Tpd is calibrated or compensated for on a
channel-by-channel basis. TSD includes factors that
normally may be difficult to calibrate, and therefore
directly impact overall system timing accuracy.
Propagation delay dispersion is defined as the maximum
deviation of the propagation delay taken at the eight
measurement points (see Figure 10) for 1V and 3V input
signals described below. The parameters of interest are:
Slew rate
Edge direction
Overdrive
Common mode voltage.
Low dispersion numbers indicate the accuracy of a
system under a variety of input conditions, and are an
important figure of merit for any comparator.
While not production tested, the Edg670 is designed
specifically to exhibit low dispersion. The typical Edge670
will show less than 25 ps Tpd dispersion.
