Figure 13. Output Enable Control Registers
3.8. Power Consumption
The Si5338 Power consumption is a function of
Supply voltage
Frequency of output Clocks
Number of output Clocks
Format of output Clocks
Because of internal voltage regulation, the current from
the core VDD is independent of the VDD voltage and
hence the plot shown in Figure 14 can be used to
estimate the VDD core (pins 7 and 24) current.
The current from the output supply voltages can be
estimated from the values provided in Table 3, “DC
Characteristics,” on page 5. To get the most accurate
value
for
VDD
currents,
the
Si5338-EVB
with
Clockbuilder software should be used. To do this, go to
the
“Power”
tab
of
the
Clockbuilder
and
press
“Measure”. In this manner, a specific configuration can
be implemented on the EVB and the actual current for
each supply voltage measured. When doing this it is
critical that the output drivers have the proper load
impedance for the selected format.
When testing for output driver current with HSTL and
SSTL, it is required to have load circuitry as shown in
“AN408: Termination Options for Any-Frequency, Any-
Output Clock Generators and Clock Buffers”. The
Si5338 EVB has layout pads that can be used for this
purpose. When testing for output driver current with
LVPECL the same layout pads can be used to
implement the LVPECL bias resistor of 130
(2.5 V
VDDx) or 200
(3.3 V VDDx). See the schematic in the
Si5338-EVB data sheet and AN408 for additional
information.
