CDR1 Ground. Isolated ground for the internal CDR1.
CDR2 Ground. Isolated ground for the internal CDR2.
X4PLL Ground. Isolated ground for the internal X4PLL.
SFPLL Ground. Isolated ground for the internal SFPLL.
DS3PLL Ground. Isolated ground for the internal DS3PLL.
E3PLL Ground. Isolated ground for the internal E3PLL.
CDR1 Power. 1.5 V power supply for the internal CDR1, which is used by
the high-speed receive CDR, the protection receive CDR and the three
CDRs associated with the mate interconnect ports. Good engineering prac-
tice needs to be applied; refer to the evaluation board schematic.
CDR2 Power. 1.5 V power supply for the internal CDR2, which is used by
the high-speed receive CDR, the protection receive CDR and the three
CDRs associated with the mate interconnect ports. Good engineering prac-
tice needs to be applied; refer to the evaluation board schematic.
X4PLL Power. 1.5 V power supply for the internal X4PLL, which is used for
the transmit protection 1 + 1 port. Good engineering practice needs to be
applied; refer to the System Design Guide.
DS3PLL Power. 1.5 V power supply for the internal DS3PLL, which is used
by the DS3DJA. Good engineering practice needs to be applied; refer to the
evaluation board schematic.
E3PLL Power. 1.5 V power supply for the internal E3PLL, which is used by
the E3DJA. Good engineering practice needs to be applied; refer to the Sys-
tem Design Guide.
SFPLL Power. 3.3 V power supply for the internal SFPLL, which is used by
the CG block. Good engineering practice needs to be applied; refer to the
evaluation board schematic.
