Powerdown Demultiplexer Circuit (Active-Low).
0 = demultiplexer powered off, D[15:0]P/N and PARITYP/N
1 or no connection = demultiplexer powered on
Mute Data to Demultiplexer Circuit (Active-Low).
0 = mute data
1 or no connection = normal data
Recovered Clock Output (155 MHz).
155 MHz recovered differential clock output. Pins are active
but forced to differential logic low when MUTE155N = 0.
Mute CK155P/N Clock Output (Active-Low). Forces
CK155P/N to logic low when MUTE155N is active.
0 = muted
1 or no connection = enabled
Parity Input Over Data (D[15:0]). Active only when
PDDMXN = 1.
Reference Clock Input (155 MHz). This clock is optional. If
applying the REFCLKP/N, set the REFCLKP/N to one of
the following frequencies:
Reference Select to PLL. Selects LAINP/N or DATAP/N, or
REFCLKP/N as the input to the CDR PLL.
0 = select REFCLKP/N
1 or no connection = select LAINP/N or DATAP/N
