Vectron FX-500 Low jitter frequency translator Datasheet

FX-500
Low Jitter Frequency Translator
FX-500
Description
The FX-500 is a complete crystal-based frequency translator used in communications applications where low jitter is paramount.
Performance advantages include superior jitter performance, high output frequencies and small package size. Advanced custom
ASIC technology results in a highly robust, reliable and predictable device.
The device is packaged in a 6 pin J-Lead ceramic package with a hermetic seam welded lid.

1. A 0.1 μF low frequency tantalum bypass capacitor in parallel with a 0.01 μF high frequency ceramic capacitor is recommended.
2. Figure 2 defines the waveform parameters. Figure 3 illustrates the standard test conditions under which these parameters are specified and
tested.
3. Duty cycle is defined as (on time÷period), with VS = VDD/2, per figure 2. Duty cycle is measured with a 15pf load per figure 3.
4. Other frequencies may be available, please contact factory.

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 the
maximum ratings for the 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 device has been qualified to meet the JEDEC
standard for Pb-Free assembly. The temperatures
and time intervals listed are based on the PbFree small body requirements. The temperatures
refer to the topside of the package, measured on
the package body surface. The FX-500 device is
hermetically sealed so an aqueous wash is not an
issue.

1.
Tristate is driven to logic high or logic low; there is no internal pull up or pull down resistor.
2.
LD is an open collector output requiring a 30k ohm pullup resistor to VDD. LD output is logic high under locked condition,
logic low for no input at fIN, and for “out-of-lock” condition LD transitions between logic low and logic high at the phase detector
