Output Logic Characteristics
See
“Output Termination Recommendations” for
illustrations. In cases where single-ended output is desired,
the designer should terminate the unused complimentary
output in the same manner as the normal output that is
being used. Unused output pairs can be left floating.
LVPECL operation:
Typical voltage swing is 700mV
PP to 800mVPP into
50
.
Common mode voltage is V
CC–1.3V, typical.
100
termination across the output pair is NOT
recommended for LVPECL. See
“Output Termination”
section, Figures 5 to 7.
HSTL operation (Bank B):
Typical voltage swing is 250mV
PP to 450mVPP into
effective 50
.
Thermal Considerations
This part has an exposed die pad for enhanced heat
dissipation. We strongly recommend soldering the exposed
die pad to a ground plane. Where this is not possible, we
recommend maintaining at least 500lfpm air flow around
the part.
For additional information on exposed-pad characteristics
and implementation details, see Amkor Technology’s web
site, www.amkor.com.
REFCLK Input Interface
The flexible REFCLK inputs are designed to accept any
differential or single-ended input signal within 300mV above
VCC and 300mV below ground.
Do not leave unused REFCLK inputs floating. Tie either
the true or complement inputs to ground, but not both. A
logic zero is achieved by connecting the complement input
to ground with the true input floating. For a TTL input, tie a
resistor between the complement input and ground. See
“Input Interface” section, Figures 4a through 4h.
Input Levels
LVDS, CML and HSTL differential signals may be
connected directly to the REFCLK inputs. Depending on
the actual worst case voltage seen, the minimum input
voltage swing varies.
