FX-402-ECT-SC

FX-402 Low Jitter Frequency Translator Previous Part Number FX-427 FX-402 Description The FX-402 is a precision quartz-based frequency translator used to translate 1 to 4 selected input clocks as low as 8 kHz to an integer multiple as high as 850 MHz. The FX-402’s superior jitter performance is achieved through the filtering action of the onboard voltage-controlled SAW oscillator (VCSO) and integrated loop filter. Two low-jitter outputs are provided. Monitoring and control functionality are also standard features.

Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Table 2.

Environmental Compliance Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2016 Handling Precautions Although ESD protection circuitrry has been designed into the the FX-402, proper precautions should be taken when handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance=1.5Kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes Table 4.

The temperatures and time intervals listed are based on the Pb-Free small body requirements. The temperatures refer to the topside of the package, measured on the package body surface. The FX-402 should not be subjected to a wash process that will immerse it in solvents. NO CLEAN is the recommended procedure. The FX-402 has been designed for pick and place reflow soldering. The FX-402 may be reflowed once and should not be reflowed in the inverted position. Figure 4. Suggested IR Profile Tape and Reel Table 6.
