Power Consumption of the PCS2I99447 and
Thermal Management
The PCS2I99447 AC specification is guaranteed for the
entire operating frequency range up to 350MHz. The
PCS2I99447 power consumption and the associated
long-term
reliability
may
decrease
the
maximum
frequency limit, depending on operating conditions such
as clock frequency, supply voltage, output loading,
ambient temperature, vertical convection and thermal
conductivity of package and board. This section
describes the impact of these parameters on the junction
temperature and gives a guideline to estimate the
PCS2I99447 die junction temperature and the associated
device reliability.

Increased power consumption will increase the die
junction temperature and impact the device reliability
(MTBF). According to the system-defined tolerable
MTBF, the die junction temperature of the PCS2I99447
needs to be controlled and the thermal impedance of the
board/package
should
be
optimized.
The
power
dissipated in the
PCS2I99447
is represented in
equation 1.Where ICCQ is the static current consumption
of the PCS2I99447, CPD is the power dissipation
capacitance per output,
(Μ)ΣCL represents the external
capacitive output load, N is the number of active outputs
(N is always 12 in case of the PCS2I99447). The
PCS2I99447 supports driving transmission lines to
maintain high signal integrity and tight timing parameters.
Any transmission line will hide the lumped capacitive load
at the end of the board trace, therefore,
ΣCL is zero for
controlled transmission line systems and can be
eliminated from equation 1. Using parallel termination
output termination results in equation 2 for power
dissipation.
In equation 2, P stands for the number of outputs with a
parallel or thevenin termination, VOL, IOL, VOH and IOH are
a function of the output termination technique and DCQ is
the clock signal duty cycle. If transmission lines are used
ΣCL is zero in equation 2 and can be eliminated. In
general, the use of controlled transmission line
techniques eliminates the impact of the lumped capacitive
loads at the end lines and greatly reduces the power
dissipation of the device. Equation 3 describes the die
junction temperature TJ as a function of the power
consumption.
Where Rthja is the thermal impedance of the package
(junction to ambient) and TA is the ambient temperature.
According to Table 9, the junction temperature can be
used to estimate the long-term device reliability. Further,
combining equation 1 and equation 2 results in a
maximum operating frequency for the PCS2I99447 in a
series terminated transmission line system, equation 4
