Clock Output (155 MHz).
155 MHz differential clock output.
Note that this clock frequency will scale by 15/14 when
operating at the FEC rate.
Enable CK155P/N Clock Output (Active-Low).
0 = CK155P/N buffer enabled
1 or no connection = CK155P/N buffer powered off
Parallel Input Clock (622 MHz).
622 MHz differential clock
input used to register parallel data when using forward
directional clocking mode. Note that this clock frequency will
scale by 15/14 when operating at the FEC rate.
Clock Mode Select.
Selects clocking method for data transfer
mode.
00 = forward directional clocking
01 = clockless transfer
11 or no connections = contraclocking
Loss of Lock (Active-Low).
0 = PLL out of lock
External Center.
Centers the pointers in the parallel data
storage element.
Data Storage Overflow.
Indicates (active high) when an
overflow has occurred in the parallel data storage element.
Reference Clock Input (622.08 MHz or 155.52 MHz).
Note that this clock frequency must scale by 15/14 when
operating the device at the FEC rate.
Reference Clock Frequency.
Selects frequency of
REFCLKP/N.
0 = 155 MHz
1 or no connection = 622 MHz
Loop Filter PLL.
Connect LFP and LFN to loop filter (see

Name/Description
Reset (Active-Low).
Resets all synchronous logic. During a
reset, the true data outputs are in the low state and the barred
data outputs are in the high state. Reset must be held active low
for a minimum of 6.4 ns while the internal oscillator is active.
0 = reset
1 or no connection = normal operation
