Controls or marks one-second
interval used for counter
latching. When input, the timer
is aligned to ONESEC rising
edge. When output, rising
edge indicates start of each
one-second interval. When
output, derived from TXCKI1
clock of the first framer. The
ONESEC pulse length is 16
clocks.
These pins must be connected
to 5 V if 5 V input tolerance is
required; if not, it must be
connected to 3.3 V.
Resets all counters and
registers to their default values
(active low).
Setting this pin high forces all
the output/inputs on the device
to drive High Z, regardless of
the state of the internal state
machines, and the frame
processing taking place at the
same time. Setting this pin low
enable the output/inputs to
normal driving state.
For Conexant use only. Must
be connected to ground.
The core is provided with 2.5 V
using these pins.
Note: Refer to
Power Ramp Sequence of
VDDx and
These pins should be
connected to a 3.3 V power
supply.
