Phase Noise and Phase Jitter Integration
Phase noise is measured in the frequency domain, and is
expressed as a ratio of signal power to noise power measured
in a 1Hz bandwidth at an offset frequency from the carrier, e.g.
10Hz, 100Hz, 1kHz, 10kHz, 100kHz, etc. Phase noise measurement is made with an Agilent E5052A Signal Source Analyzer (SSA) with built-in outstanding low-noise DC power
supply source. The DC source is floated from the ground and
isolated from external noise to ensure accuracy and repeatability.
In order to determine the total noise power over a certain
frequency range (bandwidth), the time domain must be
analyzed in the frequency domain, and then reconstructed in
the time domain into an rms value with the unwanted frequencies excluded. This may be done by converting L(f) back to
Sφ(f) over the bandwidth of interest, integrating and performing some calculations.
The value of RMS jitter over the bandwidth of interest, e.g.
10kHz to 20MHz, 10Hz to 20MHz, represents 1 standard deviation of phase jitter contributed by the noise in that defined
bandwidth.
QT93W and QT93P SERIES
2.5 to 3.3Vdc - 40MHz to 320MHz
Figure 1 shows a typical Phase Noise/Phase jitter of a
QT93LW, 3.3Vdc, 250MHz clock at offset frequencies 10Hz to
10MHz, and phase jitter integrated over the bandwidth of
12kHz to 20MHz.
Thermal Characteristics
The heat transfer model in a hybrid package is described in
figure 2.
Heat spreading occurs when heat flows into a material layer of
increased cross-sectional area. It is adequate to assume that
spreading occurs at a 45° angle.
The total thermal resistance is calculated by summing the
thermal resistances of each material in the thermal path
between the device and hybrid case.
RT = R1 + R2 + R3 + R4 + R5
The total thermal resistance RT (see figure 3) between the heat
source (die) to the hybrid case is the Theta Junction to Case
(Theta JC) in°C/W.
• Theta junction to case (Theta JC) for this product is 35°C/W.
• Theta case to ambient (Theta CA) for this part is 100°C/W.
• Theta Junction to ambient (Theta JA) is 135°C/W.
(Figure 1)
(Figure 2)
Maximum power dissipation PD for this package at 25°C is:
• PD(max) = (TJ (max) – TA)/Theta JA
• With TJ = 175°C (Maximum junction temperature of die)
• PD(max) = (175 – 25)/135 = 1.11W
