Reflow and Soldering Techniques

Unless otherwise specified, soldering should be performed on terminals at 260ºC for 10s maximum. Do not apply soldering heat on
oscillator package since it could damage the unit. Hand soldering is recommended. Wave solder at 245ºC for 15s max.

Thermal Characteristics

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

1.8 to 5.0Vdc - 15kHz to 160MHz

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

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-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 QT89L-24MHz, at 3.3Vdc.

1.8 to 5.0Vdc - 15kHz to 160MHz

Phase Noise and Phase Jitter Integration

RMS jitter (1σ): 8.19ps Peak-to-peak jitter: 76ps

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 QT89L, 3.3Vdc, 50MHz clock at offset frequencies 10Hz to 5MHz, and
phase jitter integrated over the bandwidth of 12kHz to 1MHz.
