VECTRON FX-703

FX-703
Low Jitter VCSO Frequency Translator
Jitter Attenuator
FX-703
Description
The FX-703 is a low jitter precision frequency translator used to translate input frequencies such as 19.44, 38.88, 77.76 MHz, etc.
to a binary multiple frequency as high as 1 GHz. The FX-703’s superior jitter performance is achieved through the PLL’s integrated
VCSO. The FX-703 is housed in a hermetically sealed leadless surface mount package offered on tape and reel.

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 circuitry has been designed into the the FX-703, proper precautions should be taken when handling
and mounting. VI employs a Human Body Model (HBM) 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.

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-703 device is
hermetically sealed so an aqueous wash is not an
issue.

It is recommended that the Lock Detect circuit shown in Figure 6 be used for smoothing the FX-703 lock detect signal. The circuit takes the lock detect output and performs a peak follower. When out of lock, the outpuit is VCC – 1V. Under locked conditions, it is ground.
Do not leave the MODE pin floating, it should be set to logic 0 or ground for normal operation.
BRCLK and CBRCLK should be left floating if not used.
FIN, CFIN, BRCLK, and CBRCLK have internal pull-up/pull-down resistors and it is recommended to AC couple these inputs.
Best jitter is realized with a differential input.

Figure 7. Typical FX-703 Application Diagram Consult with Vectron Application Engineering for recommended Loop Filter design. The lock detect
has a low current output drive with narrow pulses occuring at the phase detector edge rate even
under locked conditions. Figure 7 shows one method to buffer and filter the LD output.
Figure 8. LVDS Input, LVDS Output
The inputs, Fin and CFin, are biased with 13 kΩ pull up and pull down resistors which sets the
mid supply bias on the input differential amplifier. In most applications, the input should be ACcoupled. For best signal integrity, the shown terminatiosn should be used.
