5 x 7.5 x 2.5 mm Package Frequency Translation up to 850 MHz VCSO based PLL for Ultra-Low Jitter CMOS / LVDS / LVPECL Inputs compatible Differential LVPECL or LVDS Output CMOS Lock Detect External Divider for Input Frequencies < 19 MHz 0°/70°C or -40°/+85°C Temperature Range Fully Compatible for Lead Free Assembly
Description
The FX-730 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 850 MHz. The FX-730’s superior jitter performance is achieved through the PLL’s integrated VCSO. The FX-730 is housed in a hermetically sealed leadless surface mount package offered on tape and reel.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Also, exposure to these absolute maximum ratings for extended periods can adversely affect device reliability. Functional operation is not implied at these or any other conditions in excess of those represented in the operational sections of this data sheet. Permanent damage is also possible if any device input draws greater than 100 mA.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The FX-730 family is undergoing the following qualification tests:

Handling Precautions
Although ESD protection circuitry has been designed into the FX-730 proper precautions should be taken when handling and mounting. VI employs a human body model (HBM), a charged-device model (CDM), and machine model (MM) for ESD susceptibility testing and design protection evaluation.

Temperature (DegC)
The device has been qualified 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-730 device is hermetically sealed so an aqueous wash is not an issue.
