Function
The active-low test reset (TRSTB) signal provides
an asynchronous S/UNI-STAR test access port
reset via the IEEE P1149.1 test access port.
TRSTB is a Schmitt triggered input with an integral
pull-up resistor.
Note that when not being used, TRSTB must be
connected to the RSTB input.
Function
The analog CP and CN pins are provided for
applications that must meet SONET/SDH jitter
transfer specifications. A TBD nF ceramic capacitor
can be attached across C+ and C-.
The Analog Test Bus (ATB). These pins are used
for manufacturing testing only and should be
connected ground.
Function
I/O Bias (BIAS). When tied to +5V via a 1 K
resistor, the BIAS input is used to bias the wells in
the input and I/O pads so that the pads can tolerate
5V on their inputs without forward biasing internal
ESD protection devices. When BIAS is tied to
+3.3V, the inputs and bi-directional inputs will only
tolerate 3.3V level inputs.
