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.

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.

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

Applications
•  Wireless Infrastructure
•  802.16 BTS
•  10 Gigabit FC
•  10GbE LAN / WAN
•  OADM and IP Routers
•  Test Equipment
