FX-702

Low Jitter VCSO Frequency Translator

Previous Part Numbers FX-703, FX-730

The FX-702 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-702’s superior jitter performance is achieved through the PLL’s integrated

VCSO. The FX-702 is housed in a hermetically sealed leadless surface mount package oered on tape and reel.

1. See Standard Frequencies and Ordering Information.

2. Parameters are tested with production test circuit below (Fig 2).

3. Parameters are tested at ambient temperature with test limits guard banded for specied operating temperature.

4. Measured from 20% to 80% of a full output swing (Fig 3).

5. Not tested in production, guaranteed by design, veried at qualication.

6. Minimum Input Low Voltage not to exceed 2.125 V. Minimum Input High Voltage not to go below 1.49 V.

7. AC coupling is recommended. There is an internal pull-up and pull-down resistor on all clock inputs (Fin, BRCLK).

8. Measured using a Wavecrest SIA3300. Best results are realized with a dierential input.

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 aect device reliability.

The FX-702 is capable of meeting the following qualication tests:

Although ESD protection circuitry has been designed into the FX-702, 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 dene the model.

Figure 4. Suggested IR Prole

The device has been qualied to meet the JEDEC

standard 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-702 device is

hermetically sealed so an aqueous wash is not an

issue.

1. It is recommended that the Lock Detect circuit shown in Figure 7 be used for smoothing the FX-702 lock detect signal. The circuit

takes the lock detect output and performs a peak follower. When out of lock, the output is VCC - 1V. Under locked conditions, it is ground.

2. Do not leave the MODE pin oating, it should be set to logic 0 or ground for normal operation.

3. BRCLK and CBRCLK should be left oating if not used.

4. FIN, CFIN, BRCLK, and CBRCLK have internal pull-up/pull-down resistors and it is recommended to AC couple these inputs.

5. Best jitter is realized with a dierential input.

Figure 7. Typical FX-702 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 buer and lter 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 dierential amplier. In most applications, the input should be AC-

coupled. For best signal integrity, the shown terminatiosn should be used.

Ordering Information

1. Not all combinations are possible. Please consult with your Vectron representative for application assistance. Other frequencies available upon request.

2. When ordering the FX-702 with the external divider option, the prescaler is set to 1. The Feedback Divider = FOUT/FIN.

3. Vectron will determine and recommend a specic part number based upon the application. The Enhanced Mode version of the FX-702 activates additional

internal dividers.
