Product Data SheetFX-101Frequency TranslatorOutput frequencies up to 77.760 MHzLocked to specified Input frequency, e.g. 8 kHz 1" x 0.8" x 0.2", Surface Mount (FR4 base)Single 5.0 Vdc or 3.3 Vdc supply Optional CMOS or PECL Output Low Output JitterSONET / SDH / ATM / DSL-PON interconnects 8 kHz/16.384 MHz/19.44 MHz to 77.76 MHz8 kHz/1.544 MHz/2.048 MHz to 44.736MHzVectron's FX-101 is a crystal based frequency translator which is used to translate any input frequency such as 8 kHz, 1.544 MHz, 2.048 MHz, 19.440 MHz etc. to any specific frequency less than or equal to 77.76 MHz. The input frequency does not have to be a 50/50% duty cycle and as an example can be an 8 kHz signal with a logic high "on time" of only 1us, such as a BITS clock. The FX-101 also has the ability to translate up to any of 4 different input frequencies to one common output frequency, such as input frequencies of 8 kHz and 1.544 MHz and 19.44 MHz and any other frequency between 333 Hz and 77.76 MHz translating them to an output frequency up to 77.76 MHz.The "Input Frequency tracking capability" is the total amount of input frequency deviation in which the FX-101 is guaranteed to track or translate. As an example, a typical input clock would be 8 kHz ± 20 ppm. The FX-101 is guaranteed to track at least ±50 ppm of error over temperature/ aging/ power supply and is more than twice what most applications require. The PLL control voltage is brought out through a 470K ohm resistor. This would allow for the use of external circuitry (analog comparators or an A/D converter plus a processor) to detect when the control voltage is getting close to the limits of the pull range.(1.00)@ 140ºC to 160ºC @ >183ºCT e m p e r a t u r e ( ºC)NOTE: This FX-101 should not be subjected to a wash process that will immerse it in solvents.NO CLEAN is the recommended procedure.All components outside the dotted line box are user supplied components and/or connections. This is just one possible configuration of the FX-101. For additional information about your specific needs please contact our Factory.Although protection circuitry has been designed into this device, proper precautions should be taken to avoid exposure to electrostatic discharge (ESD) during handling and mounting. VI employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the circuitparameters used to define the mode.Although no industry-wide standard has been adopted for the CDM, a standard HBM (resistance = 1500 ohms, capacitance =100pf) is widely used and therefore can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using these circuit parameters.ESD Threshold VoltageModelThreshold Unit Human-Body (HBM)Charged-Device500500V min V min。

912 SeriesD 100317XE N GInstallation GuideEnglish – May 20021. The pressure/temperature limits in this installation guide and any applicable standard or code limitation should not be exceeded.IntroductionThis installation guide provides instructions for installation,startup, and adjustment. To receive a copy of the instruction manual, contact your local Fisher Sales Office or Sales Representative or view a copy at . For further information refer to:912 Series Instruction Manual (form 5124, D100317X012).P.E.D. CategoryThis product may be used as a safety accessory with pressure equipment in the following P ressure Equipment Directive 97/23/EC categories. It may also be used outside of the P ressure Equipment Directive using sound engineering practice (SEP) per table below.E Z I S T C U D O R P SE I R O G E T A C EP Y T D I U L F )h cn i -4/1(6N D PE S 1SpecificationsBody Sizes and End Connection StylesInlet : DN 6 (1/4-inch) NPT screwedOutlet : DN 6 or DN 10 (1/4 or 3/8-inch) NPT screwedMaximum Allowable Inlet Pressure (1)17 bar (250 psig)Outlet Pressure Ranges (1)See table 1Maximum Allowable Outlet Pressure (1)Maximum Emergency Outlet Pressure : 1,4 bar (20 psig)Maximum Recommended Outlet Pressure to Avoid Internal Part Damage : 0,21 bar, differential (3 psi)above outlet pressure settingProof Test PressureAll Pressure Retaining Components have been proof tested per Directive 97/23/EC - Annex 1, Section 7.4Temperature Capabilities (1)-29 to 71°C (-20 to 160°F)InstallationOnly qualified personnel should install or service a regulator. Regulators should be installed,operated, and maintained in accordance with international and applicable codes and regulations, and Fisher instructions.If the regulator vents fluid or a leak develops in the system, it indicates that service is required.Failure to take the regulator out of service immediately may create a hazardous condition.Personal injury, equipment damage, or leakage due to escaping fluid or bursting of pressure-containing parts may result if this regulator is overpressured or is installed where service conditions could exceed the limits given in the Specifications section, or where conditions exceed any ratings of the adjacent piping or piping connections.To avoid such injury or damage, provide pressure-relieving or pressure-limiting devices (as required by the appropriate code, regulation, or standard)to prevent service conditions from exceeding limits.Additionally, physical damage to the regulator could result in personal injury and property damage due to escaping fluid. To avoid such injury and damage, install the regulator in a safe location.Clean out all pipelines before installation of the regulator and check to be sure the regulator has not been damaged or has collected foreign material during shipping. For NP T bodies, apply pipe compound to the male pipe threads. For flanged bodies, use suitable line gaskets and approved piping and bolting practices. Install the regulator in any position desired, unless otherwise specified, but be sure flow through the body is in the direction indicated by the arrow on the body.NoteIt is important that the regulator be installed so that the vent hole in the spring case is unobstructed at all times. For outdoor installations, the regulator should be located away from vehicular traffic and positioned so that water, ice, and other foreign materials cannot enter the spring case through the vent. Avoid placing the regulator beneath eaves or downspouts, and be sure it is above the probable snow level.Overpressure ProtectionThe recommended pressure limitations are stamped on the regulator nameplate. Some type of overpressure protection is needed if the actual inlet pressure exceeds the maximum operating outlet pressure rating. Overpressure protection should also be provided if the regulator inlet pressure is greater than the safe working pressure of the downstream equipment.Regulator operation below the maximum pressure limitations does not preclude the possibility of damage from external sources or debris in the line. The regulator should be inspected for damage after any overpressure condition.StartupThe regulator is factory set at approximately the midpoint of the spring range or the pressure requested, so an initial adjustment may be required to give the desired results. With proper installation completed and relief valves properly adjusted, slowly open the upstream and downstream shutoff valves.912 SeriesFor information, contact Fisher Controls, International:Within USA (800) 588-5853 – Outside USA (972) 542-0132France – (33) 23-733-4700Singapore – (65) 770-8320Mexico – (52) 57-28-0888©Fisher Controls International, Inc., 2002; All Rights ReservedFisher and Fisher Regulators are marks owned by Fisher Controls International, Inc.

Monitor the outlet pressure with a test gauge during the adjustment. Replace the closing cap or tighten the locknut to maintain the desired setting.Taking Out of Service (Shutdown)To avoid personal injury resulting from sudden release of pressure, isolate the regulator from all pressure before attempting disassembly.NO I T A R U G I F N O C E L B A L I A V A EG N A R E R U S S E R P T E L T U O )g i s p /.c .w s e h c n i (r a b TA G N I T T E S E R U S S E R P T E L T U O E V OB A T N I O P E T A M I X O R P P A EG R A H C S I D O T S T R A T S F E I L E R L A N R E T N I H C I H W )g i s p /.c .w s e h c n i (r a b le e h w d n a h t u o h t i w 219e p y T )7o t 3(71o t 7)01o t 5(52o t 21)31o t 52.9(23o t 32)42o t 21(06o t 03)12o t 5(25o t 21)03o t 8(57o t 02)93o t 61(79o t 04)g i s p 3o t 71(012o t 24l e e h w d n a h t u o h t i w H 219e p y T )5.2o t 1(271o t 96)5o t 7.2(043o t 681)8.6o t 7.0(74,0o t 50,0)5.21o t 8.3(68,0o t 62,0le e h w d n a h h t i w s e i r e S 219)1o t 0(96o t 0)5o t 0(043o t 0)3o t 0(012o t 0)5.21o t 0(68,0o t 0Table 1.
