FX-424DPC-A1G

FX-424 Low Jitter Frequency Translator FX-424 Description The FX-424 is a precision quartz-based frequency translator used to translate an input frequency such as 8 kHz, 1.544 MHz, 2.048 MHz, 19.44 MHz etc. to any specific frequency from 1.544 MHz to 1.0 GHz. The FX-424 can perform either up or down frequency conversion. The FX-424’s superior jitter performance is achieved through the use of a precision VCXO or VCSO. With the use of an external multiplexer, up to 4 different input clocks can be translated to a common output frequency.

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-424, 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-427 should not be subjected to a wash process that will immerse it in solvents. NO CLEAN is the recommended procedure. The FX-427 has been designed for pick and place reflow soldering. The FX-427 may be reflowed once and should not be reflowed in the inverted position. Figure 4. Suggested IR Profile Tape and Reel Table 6.
