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.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can permanently damage the device. 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.

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

The FX-424 is qualiﬁed to meet the JEDEC stan-

dard for Pb-Free assembly. 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.

frequencies. For example, to request samples for a translator with and operating temperature of -40 to +85°C, input frequencies of 8 kHz, 1.544 MHz,

19.44 MHz, 77.76 MHz and an output frequency of 622.08 MHz, the part number would be FX-424-DFF-A4S8, S = 8 kHz, 1.544 MHz, 19.44 MHz, 77.76
