5) Place a local ground plane on the PCB layer imme-
diately below the crystal guard ring. This helps to
isolate the crystal from noise coupling from signals
on other PCB layers.
Note: The ground plane must be in the vicinity of the
crystal only and not on the entire board.
Parameter Definitions
INL
Integral nonlinearity (INL) is the deviation of the values on
an actual transfer function from a straight line. This
straight line is either a best-straight-line fit or a line drawn
between the end points of the transfer function, once off-
set and gain errors have been nulled. INL for the
MAX11359A is measured using the end-point method.
DNL
Differential nonlinearity (DNL) is the difference between
an actual step width and the ideal value of 1 LSB. A DNL
error specification of greater than -1 LSB guarantees no
missing codes and a monotonic transfer function.
Gain Error
Gain error is the amount of deviation between the mea-
sured full-scale transition point and the ideal full-scale
transition point.
