Input References (LVCMOS, Schmitt Trigger).
These are input references
available to both DPLL1 and DPLL2 for synchronizing output clocks. All eight
input references can be automatically or manually selected using software
registers. These pins are internally pulled down to Vss.

Frame Pulse Synchronization References (LVCMOS, Schmitt Trigger).
These are the frame pulse synchronization inputs associated with input
references 0, 1 and 2. These inputs accept frame pulses in a clock format (50%
duty cycle) or a basic frame pulse format with minimum pulse width of 5 ns.
These pins are internally pulled down to V
ss.
External DPLL Feedback Clock (LVCMOS, Schmitt Trigger).
External
feedback clock input. This allows DPLL1 to adjust for PCB trace propagation
delays. This pin is internally pulled down to Vss. Leave open when not is use.

External DPLL Feedback Frame Pulse (LVCMOS, Schmitt Trigger).
External

propagation delays. This pin is internally pulled down to Vss. Leave open when
not is use.
Output Clocks and Frame Pulses
D10
sdh_clk0
O
SONET/SDH Output Clock 0 (LVCMOS).
This output can be configured to
provide any one of the SONET/SDH clock outputs up to 77.76 MHz. The default
frequency for this output is 77.76 MHz.
G10
sdh_clk1
O
SONET/SDH Output Clock 1 (LVCMOS).
This output can be configured to
provide any one of the SONET/SDH clock outputs up to 77.76 MHz. The default
frequency for this output is 19.44 MHz.
E10
sdh_fp0
O
SONET/SDH Output Frame Pulse 0 (LVCMOS).
This output can be configured
to provide virtually any style of output frame pulse synchronized with an
associated SONET/SDH family output clock. The default frequency for this frame
pulse output is 8 kHz.
F10
sdh_fp1
O
SONET/SDH Output Frame Pulse 1 (LVCMOS).
This output can be configured
to provide virtually any style of output frame pulse synchronized with an
associated SONET/SDH family output clock. The default frequency for this frame
pulse output is 2 kHz.
K9
p0_clk0
O
Programmable Synthesizer 0 - Output Clock 0 (LVCMOS).
This output can be
configured to provide any frequency with a multiple of 8 kHz up to 77.76 MHz in
addition to 2 kHz. The default frequency for this output is 2.048 MHz.
K7
p0_clk1
O
Programmable Synthesizer 0 - Output Clock 1 (LVCMOS).
This is a
programmable clock output configurable as a multiple or division of the p0_clk0
frequency within the range of 2 kHz to 77.76 MHz. The default frequency for this
output is 8.192 MHz.
