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.

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. Table 4.

PD Feedback Frequency 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. 5 of 10 Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • http://www.vectron.com 5 FX-703 Low Jitter VCSO Frequency Translator and Jitter Attenuator Rev: 03Apr2012 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. 6 of 10 Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • http://www.vectron.com 6 FX-703 Low Jitter VCSO Frequency Translator and Jitter Attenuator Rev: 03Apr2012 Figure 9. 50 Ohm Impedance Matching.
