CLOCK GENERATOR FOR CAVIUM PROCESSORS
NOTE: Pullup and Pulldown refer to internal input resistors. See Table 2, Pin Characteristics, for typical values.
Table 2. Pin Characteristics
NOTE: VDDO_X denotes VDDO_B, VDDO_CD, VDDO_E and VDDO_REF.

VDDO_E
Power
Bank E output supply pin. 3.3 V or 2.5V supply.
38
QE
Output
Single-end Bank E output. LVCMOS/LVTTL interface levels.
40
nLVDS_SEL
Input
Pulldown
Selects between LVDS and LVPECL interface levels on differential output pair QA
and nQA. When LOW, LVDS interface levels are selected. When HIGH, LVPECL
is selected. See Table 3E.
41, 48
VDDO_REF
Power
Bank QREF output supply pins. 3.3 V or 2.5V supply.
43,
44,
45
QREF2,
QREF1,
QREF0
Output
Single-ended reference clock outputs. LVCMOS/LVTTL interface levels.
47
nOE_E
Input
Pulldown
Active LOW output enable for Bank E outputs. When logic HIGH, the outputs are in
high impedance (HI-Z). When logic LOW, the outputs are enabled.
LVCMOS/LVTTL interface levels.
