Preliminary Data Sheet FX-424 Low Jitter Frequency Translator Features • Quartz-based PLL for Ultra-Low Jitter • Frequency Translation up to 850 MHz • Accepts up to 4 ext.-muxed clock inputs • CMOS / LVDS / LVPECL Inputs compatible • Differential LVPECL or LVCMOS Output • Lock Detect / Loss of Signal Alarms • Output Disable • 20.3 x 13.7 x 5.1 mm SMT package • RoHS/Lead Free Compliant Applications Description The FX-424 is a precision quartz-based frequency translator used to translate an input frequency such as 8 kHz, 1.544 MHz, 2.048 MHz, 19.44 MHz etc. to any specific frequency from 1.544 MHz to 850 MHz. The FX-424 can perform either up or down frequency conversion. The FX-424’s superior jitter performance is achieved through the use of a precision VCXO or VCSO. With the use of an external multiplexer, up to 4 different input clocks can be translated to a common output frequency. • Wireless Infrastructure • 10 Gigabit FC • 10GbE LAN / WAN • OADM and IP Routers • Test Equipment • Military Communcations Figure 1.

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-424 phase noise and jitter performance can be optimized for specific applications. Please consult with Vectron’s Application Engineers for more information. Figure 2. Test Circuit Figure 3.
