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 ?

Table 4. Absolute Maximum Ratings

Parameter Symbol Ratings Unit Power Supply V CC0 to 6 V

Storage Temperature TS -55 to 125 °C

Soldering Temp/Time T LS260/40 °C/sec

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 Conditions

Mechanical Shock MIL-STD-883, Method 2002

Mechanical Vibration MIL-STD-883, Method 2007

Solderability MIL-STD-883, Method 2003

Gross and Fine Leak MIL-STD-883, Method 1014

Resistance to Solvents 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
