Understanding the Junction Temperature Range of the
MC100ES6111
skew capabilities of the MC100ES6111, the MC100ES6111 is
specified, characterized and tested for the junction
temperature range of T
thermal performance depends on the PCB type, design,
thermal management and natural or forced air convection,
the junction temperature provides an exact way to correlate
the application specific conditions to the published
performance data of this data sheet. The correlation of the
junction temperature range to the application ambient
temperature range and vice versa can be done by
calculation:
54.4°C/W (2s2p board, 200 ft/min airflow, see
typical power consumption of 610 mW (all outputs terminated
50 ohms to V
junction temperature of the MC100ES6111 is approximately
T
example case calculates to –33°C (the maximum ambient
temperature is 77°C, see
junction temperature specification of the MC100ES6111 does
not have a significant impact on the device functionality.
However, the continuous use of the MC100ES6111 at high
ambient temperatures requires thermal management to not
exceed the specified maximum junction temperature. Please
see the Freescale application note AN1545 for a power
consumption calculation guideline.

Maintaining Lowest Device Skew
skew of 35 ps and a part-to-part skew of max. 250 ps. To
ensure low skew clock signals in the application, both outputs
of any differential output pair need to be terminated
identically, even if only one output is used. When fewer than
all nine output pairs are used, identical termination of all
output pairs within the output bank is recommended. If an
entire output bank is not used, it is recommended to leave all
of these outputs open and unterminated. This will reduce the
device power consumption while maintaining minimum
output skew.
Power Supply Bypassing
differential architecture of the MC100ES6111 supports low
noise signal operation at high frequencies. In order to
maintain its superior signal quality, all V
bypassed by high-frequency ceramic capacitors connected
to GND. If the spectral frequencies of the internally generated
switching noise on the supply pins cross the series resonant
point of an individual bypass capacitor, its overall impedance
begins to look inductive and thus increases with increasing
frequency. The parallel capacitor combination shown ensures
that a low impedance path to ground exists for frequencies
well above the noise bandwidth.
The MC100ES6111 guarantees low output-to-output bank
