The heat transfer model in a hybrid package is described in figure 1.
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 2) 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 30°C/W.
• Theta case to ambient (Theta CA) for this part is 100°C/W.
• Theta Junction to ambient (Theta JA) is 130°C/W.
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)/130 = 1.15W

QPDS-0011 (Revision H, April 2013 ) (ECO# 10850)
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.
Figure below shows a typical Phase Noise/Phase jitter of a QT66T10M, 5.0Vdc, 24MHz clock at offset frequencies 10Hz to 5MHz,
and phase jitter integrated over the bandwidth of 12kHz to 1MHz.
Phase Noise and Phase Jitter Integration
Period Jitter
As data rates increase, effects of jitter become critical with
its budgets tighter. Jitter is the deviation of a timing event
of a signal from its ideal position. Jitter is complex and
is composed of both random and deterministic jitter com-
ponents. Random jitter (RJ) is theoretically unbounded
and Gaussian in distribution. Deterministic jitter (DJ) is
bounded and does not follow any predictable distribution.
DJ is also referred to as systematic jitter. A technique to
measure period jitter (RMS) one standard deviation (1σ)
and peak-to-peak jitter in time domain is to use a high
sampling rate (>8G samples/s) digitizing oscilloscope.
Figure shows an example of peak-to-peak jitter and RMS
jitter (1σ) of a QT66T-24MHz, at 5.0Vdc.
RMS jitter (1σ): 8.20ps Peak-to-peak jitter: 70.89ps
