Thermal Characteristics
The heat transfer model in a hybrid package is described in figure 1
(Based on single ASIC design) .
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
(Figure 1)
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 24°C/W.
• Theta case to ambient (Theta CA) for this part is 105°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

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
components. 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-topeak 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 QT6AC824MHz, at 5.0Vdc.
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.
Symbol
∫L(f)
Sφ (f)=(180/Π)x√2 ∫L(f)df
RMS jitter = Sφ (f)/(fosc.360°)Jitter(in seconds) due to phase noise. Note Sφ (f) in degrees.
Integrated single side band phase noise (dBc)
Spectral density of phase modulation, also known as RMS phase error (in degrees)
Definition
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 QT6AC8, 5.0Vdc, 24MHz and a QT50T, 5.0Vdc, 60 MHz clock at offset
frequencies 10Hz to 5MHz, and phase jitter integrated over the bandwidth of 12kHz to 1MHz.
