from the Master. On receipt of this signal the Slave completes training of the DFE and 4 level slicer
then begins to transmit an S1 signal. The Master detects the S1 signal from the Slave and then
completes training of the DFE and 4 level slicer.
The EDSP also allows the designer to specify the length of time the Data Pump spends in each of
the activating substates. The default times have been optimized for best performance at either 784
kbps or 1168 kbps in the framed modes (modes 7 and 6). Reliable operation has been demonstrated
using the default values at all data rates between 272 kbps and 1168 kbps in unframed modes using
the default timing. Overall activation time can be reduced for certain applications by reducing the
activation times of the individual states.
values for each of the activating substates. After settings for each of the individual sub-state timers
has been optimized, the Master Activation Timer may be optimized to minimize the time required
between sequential activation attempts.
Transition to the Active State
The actions following detection of the S1 signal vary depending on the operating mode of the
system. The following sections describe the operation in both modes.
Unframed Signal (Modes 0,1,2,4,5)
Both Master and Slave move directly to the Active state on completion of the 4LVLDET training
functions. The devices remain in the Active state even after MAT expires. Received data are
available, and the ACTIVE indicator is asserted Active state.
