FX-427
Low Jitter Frequency Translator Features
* Quartz-based PLL for Ultra-Low Jitter * Frequency Translation up to 850 MHz * Accepts 4 externally-muxed clock inputs * LVCMOS/LVDS/LVPECL Inputs Compatible * Differential LVPECL Outputs * Lock Detect * Output Disable * 20.3 x 13.7 x 5.1 mm surface mount package * Compliant to EC RoHS Directive
Description
The FX-427 is a precision quartz-based frequency translator used to translate 1 to 4 selected input clocks as low as 8 kHz to an integer multiple as high as 850 MHz. The FX-427's superior jitter performance is achieved through the filtering action of the on-board voltage-controlled SAW oscillator (VCSO) and integrated loop filter. Two low-jitter outputs are provided. Monitoring and control functionality are also standard features.
Applications
* Wireless Infrastructure * 802.16 BTS * 10 Gigabit FC * 10GbE LAN / WAN * OADM and IP Routers * Test Equipment

See Standard Frequencies and Ordering Information. Parameters are tested with production test circuit below (Fig 2). Parameters are tested at ambient temperature with test limits guard banded for specified operating temperature. Measured from 20% to 80% of a full output swing (Fig 3). Not tested in production, guaranteed by design, verified at qualification. The FX-427 phase noise and jitter performance can be optimized for specific applications. Please consult with Vectron's Application Engineers for more information.

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.
Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The FX-427 family is undergoing the following qualification tests:
Environmental Compliance
Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2016
Handling Precautions
Although ESD protection circuitry has been designed into the FX-427 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

Temperature (DegC)
The FX-427 is 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-427 should not be subjected to a wash process that will immerse it in solvents. NO .CLEAN is the recommended procedure. The FX-427 has been designed for pick and place reflow soldering. The FX-427 may be reflowed once and should not be reflowed in the inverted position.
