Understanding the Junction Temperature Range
of the MC100ES6222
skew capabilities of the MC100ES6222, the MC100ES6222
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:
17°C/W (2s2p board, 200 ft/min airflow, see
Resistance) and a typical power consumption of 1026 mW
(all outputs terminated 50 ohms to V
frequency independent), the junction temperature of the
MC100ES6222 is approximately T
minimum ambient temperature in this example case
calculates to –17°C (the maximum ambient temperature
is 93°C, see
temperature specification of the MC100ES6222 does not
have a significant impact on the device functionality.
However, the continuous use the MC100ES6222 at high
ambient temperatures requires thermal management to not
exceed the specified maximum junction temperature. Please
see the application note AN1545 for a power consumption
calculation guideline.

Maintaining Lowest Device Skew
skew of 130 ps and a part-to-part skew of max. 300 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. This will
reduce the device power consumption while maintaining
minimum output skew.
Power Supply Bypassing
differential architecture of the MC100ES6222 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.
