data sheet #: sg152 p age 2 of 8 rev: 00 date: 5/2/07 ? copyright 2007 the connor-winfield corp. all rights reserved specifications subject to change without notice the SFX-200G is a high precision frequency translator that translates one of two inputs, greater than 1mhz, to one of two selectable output frequencies between 77.76 mhz and 777.6 mhz. the SFX-200G supports all major fec rates such as 15/ 14, 255/237 etc. SFX-200G is well suited for use in line cards, service termination cards and similar functions to provide reliable reference, phase locked, synchronization for tdm, pdh, sonet and sdh networ k equipment. the SFX-200G provides a jitter filtered, wander following output signal synchronized to functional block diagram figure 1 a superior stratum or peer input reference signal. the SFX-200G includes a lock detect alar m output. the pll control voltage is brought out through a 470 k ? resistor and can be used to determine when the pull range limits are reached. the l vpecl outputs may be put into the tri-state high impedance condition for exter nal testing pur poses by asserting a high signal to the enable/disable pin. the SFX-200G package typical dimensions are 1.2" x 1.0" x 0.285". parts are assembled using high temperature solder to withstand surface mount reflow process. absolute maximum rating tab le 1 symbol parameter minimum nominal maximum units n otes vcc power supply voltage (optionc) -0.3 5.5 volts power supply voltage (optiond) -0.3 3.8 volts v i input voltage -0.2 vcc volts ts storage temperature (opti onf) -55 125 c storage temperature (opti onc) -40 85 c general description frequency divider loop filter pecl vcxo 1 pecl vcxo 2 frequency divider q (pin 12) q (pin 14) in (pin 1) in sel (pin 7) ld (pin 10) out sel (pin 8) disable (pin 16) monitor (pin 11) microprocessor 470 k ? cin (pin 2) *note 2.0 input a input b SFX-200G
