slipping that occurs in the initial
frequency acquisition of both the
Tx and Rx PLLs.
When the local port is in State 0,
it is in the reset state, where both
local Tx and Rx parallel interfaces
are disabled. The local Tx trans-
mits FF0 continuously, and the
local Rx PLL is in the frequency
detection mode. When the local
Rx is phase-locked to the remote
Tx, it transitions to State 1. The
local Tx transmits FF1 to
acknowledge the phase-locked
condition (its parallel input is still
disabled). The local Rx PLL is in
the phase detection mode and its
Figure 15 shows the state
diagram of the SMC. The SMC is
debounced by allowing state
transitions to be made only after
at least 2 consecutive frames give
the same indication. This prevents
single bit errors from causing
false state transitions. In addition
to this debouncing mechanism,
when two consecutive ERROR or
Resets occur, a timer is enabled
forcing the SMC into state zero
for 128 frame times. Any
transition out of this initial state
can only occur after the link has
been error-free for 128 frames.
This prevents false transitions
from being made during the bit-
parallel output is enabled. When
in State 2, the two-way synchroni-
zation between the local port and
the remote port is established.
Both local Tx and Rx parallel
interfaces are enabled, and the
local Rx PLL is in the phase detec-
tion mode. Parallel data can be
sent by the local Tx, and at the
same time, received by the local
Rx.
The Rx chip has the state machine
logic built in. The SMC has two
status outputs, STAT0 and STAT1,
that control the various features
of the two chips depending on the
current state. The TX inputs that
need to be controlled are FF and
ED. The Rx inputs that need to be
controlled are FDIS and ACTIVE.
To control the chips as shown in
the state diagram of Figure 15,
the following interchip
connections must be made
(Figure 16):
Tx FF is driven by STAT1
Tx ED is driven by STAT0
Rx FDIS is driven by STAT1
Rx ACTIVE is driven by STAT1
Tx RST and Rx SMCRST0 are
driven by a power-on, or user,
reset circuit.
