FX-428-DPC-C4PMB

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 Figure 1.

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.
