Ball
Symbol
*
* Differential pairs are indicated by P and N suffixes. For nondifferential pins, N at the end of the symbol name designates active-low.
I = input, O = output. I
indicates an internal pull-up resistor on this pin. Id indicates an internal pull-down resistor on this pin. It = an
internal termination resistance of 50
to V
CCD
on this pin.

Clock Output (155 MHz).
155 MHz differential clock output.
Note:
This clock frequency will scale when operating at different rates.
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 311 MHz).
622 MHz or 311 MHz
differential clock input used to register parallel data when using forward
directional clocking mode.
Note:
This clock frequency will scale when operating at different rates.
Clock Mode Select.
Selects clocking method for data transfer mode.
[0] [1]
0 0 = Forward directional clocking mode (622 MHz).
0 1 = Forward directional clocking mode (311 MHz).
1 0 = Contraclocking mode.
1 1 or no connections = Clockless mode.
Loss of Lock (Active-Low).
0 = PLL out of lock.
External Center.
Centers the pointers in the parallel data storage
element. Connected to OVRFLW for fastest FIFO overrun recovery.
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:
This clock frequency will scale when operating at different rates.
Reference Clock Frequency.
Selects frequency of REFCLKP/N.
0 = 155 MHz.
1 or no connection = 622 MHz.
Analog
Loop Filter PLL.
Connect LFP and LFN to loop filter (see Table 6 on
page 11).
Analog
Resistor Reference LVDS.
LVDS bias reference resistor. Connect a
1.5 k
resistor to V
