The clock conditioning circuit can advance or delay the
clock up to 8 ns (in increments of 0.25 ns) relative to the
positive edge of the incoming reference clock. The system
also allows for the selection of output frequency clock
phases of 0° and 180°.
Prior to the application of signals to the rib drivers, they
pass through programmable delay units, one per global
network. These units permit the delaying of global
signals relative to other signals to assist in the control of
input set-up times. Not all possible combinations of input
and output modes can be used. The degrees of freedom
available in the bidirectional global pad system and in
the clock conditioning circuit have been restricted. This
avoids unnecessary and unwieldy design kit and software
work.
Notes:
1. FBDLY is a programmable delay line from 0 to 4 ns in 250 ps increments.
2. DLYA and DLYB are programmable delay lines, each with selectable values 0 ps, 250 ps, 500 ps, and 4 ns.
3. OBDIV will also divide the phase-shift since it takes place after the PLL Core.
