Product Data SheetFX-104Frequency TranslatorFeatures• Output frequencies up to 777.60 MHz• Jitter Generation OC-192 compliant• Jitter transfer per GR-253-CORE• Single 5 or 3.3 Vdc supply• Locked to specified Input frequency, e.g. 8 kHz• 1 x 0.8 x 0.25 , Surface Mount (FR4 base)Applications• SONET / SDH / ATM• DWDM / FDM• DSL-PON Interconnects• FEC (Forward Error Correction)FX-104 Frequency TranslatorDescriptionVectron\'s FX-104 is a SAW based frequency translatorwhich is used to translate any input frequency such as8 kHz, 1.544 MHz, 2.048 MHz, 19.440 MHz etc. to anyspecific frequency from 170 MHz to 777.6 MHz. Theinput frequency does not have to be a 50/50% dutycycle and as an example can be an 8 kHz signal with alogic high on time of only 1us, such as a BITS clock.The FX-104 also has the ability to translate any of 1 to4 different input frequencies to one common output fre-quency, such as input frequencies of 8 kHz and 1.544MHz and 19.44 MHz and any other frequency between333 Hz and 170 MHz translating them to any specificoutput frequency from 170 MHz to 777.600 MHz.The Input Frequency tracking capability is the totalamount of input frequency deviation in which the FX-104 is guaranteed to track or translate. As an example,a typical input clock would be 8 kHz ±20 ppm. The FX-104 is guaranteed to track at least ±40 ppm of error overtemperature/ aging/ power supply and is more thantwice what most applications require. The PLL controlvoltage is brought out through a 470K ohm resistor. Thiswould allow for the use of external circuitry (analogcomparators or an A/D converter plus a processor) todetect when the control voltage is getting close to thelimits of the pull range.Performance CharacteristicsParameterOutput FrequenciesSupply Voltage,Supply CurrentInput Signal,OUTPUT,VOLC= 5 VdcD= 3.3 VdcA= HCMOSD= PECLF= Comp PECLVccVccIccCLKINCLKIN---VOLVOHtR/tFSymSymbolMin155.524.753.15Typical5.003.3095HCMOSPECLPECLMax777.65.253.45125UnitMHzVdcVdcmA---------VVps%pspsdBppm---Vcc-1.95Vcc-0.9845---Vcc-1.63Vcc-0.7540055150.1VOHRise/Fall Time (20% to 80%)Output SymmetryJitter Generation, rms(12 kHz to 20 MHz)Jitter Generation, rms(cycle to cycle method)Jitter Transfer, GR-253-CORE sec 5.6.2.1.2Input Frequency Tracking Capability(Can translate a Stratum 1,2,3,3E,4or SONET Min source)Operating TemperatureSize25049/510.233APR±40Temp RangeC= 0°C to +70°CTemp RangeF= -40°C to +85°C25.4 x 20.32 x 6.35 mm (1.0” x 0.8” x 0.25”)Vectron International •267 Lowell Road, Hudson, NH 03051• Tel: 1-88-VECTRON-1 • Web: www.vectron.comFX-104 Frequency TranslatorOutline DrawingPin OutPin1SymbolCLKINFunctionInput Frequency- The FX-104 series AC couples the input, this means the unit is capable ofhandling HCMOS, LvHCMOS, PECL and LvPECL input signals.(For Input Frequencies below 1 MHz only HCMOS and LvHCMOS are supported)GroundLock DetectLogic “1” indicates a locked conditionLogic “0” indicates that no input signal is present or the input signal has moved out of thelock range.PLL/ VCXO control voltageUnder locked conditions, should be 0.3V and 3.0V for the 3.3 volt option or 0.5V and 4.5V for the 5 volt option.

NO CLEAN is the rec-ommended procedure. The FX-100 series has been designed for pick and place reflow soldering. The suggested reflow pro-file is shown above. The FX-100 series may be reflowed once, and should not be reflowed in the inverted position.Vectron International •267 Lowell Road, Hudson, NH 03051• Tel: 1-88-VECTRON-1 • Web: www.vectron.comFX-104 Frequency TranslatorStandard Shipping MethodThe Standard ship method for volume production of theFX-100 series is in a matrix tray. These trays are 100%recyclable. The trays also offer the added feature thatthey can be continuously feed into a pick-n-placemachine eliminating the down time required with tape-n-reel.Handling PrecautionsAlthough protection circuitry has been designed into thisdevice, proper precautions should be taken to avoidexposure to electrostatic discharge (ESD) during han-dling and mounting. VI employs a human-body model(HBM) for ESD-susceptibility testing and protectiondesign evaluation.ESD voltage thresholds are dependent on the circuitparameters used to define the mode.
