FX-702

FX-702 Low Jitter VCSO Frequency Translator Previous Part Number FX-730 FX-702 Description The FX-702 is a low jitter precision frequency translator used to translate input frequencies such as 19.44, 38.88, 77.76 MHz, etc. to a binary multiple frequency as high as 850 MHz. The FX-702’s superior jitter performance is achieved through the PLL’s integrated VCSO. The FX-702 is housed in a hermetically sealed leadless surface mount package offered on tape and reel. Features 5 x 7.5 x 2.5 mm Package Frequency Translation up to 850 MHz VCSO based PLL for Ultra-Low Jitter CMOS / LVDS / LVPECL Inputs compatible Differential LVPECL or LVDS Output CMOS Lock Detect External Divider for Input Frequencies < 19 MHz 0°/70°C or -40°/+85°C Temperature Range Fully Compatible for Lead Free Assembly www.DataSheet4U.com Applications SONET/SDH 10GbE./10.3GbE Frequency Translation Clock Smoothing, Clock Switching FEC Scaling Block Diagram VCC (10) FIN (12) CFIN (11) LD (2) Phase Detector & LD LFN (6) Charge Pump CFLN (7) VCSO ÷1, ÷4 MODE (4) Switch External Divider ÷1, ÷4, ÷8, ÷16, ÷32 ÷1, ÷2, ÷4 FOUT (8) CFOUT (9) BRCLK CBRCLK (4) (1) GND (3, 5, 13) Figure 1.
