A positive current source, and the other Q output enables a negative current source. These current sources are known as the charge pump. For more details on PFD operation, consult “Phase-Locked Loops for High Frequency Receivers and Transmitters.”Using this architecture, the input to +IN below is at a higher frequency than the –IN (Figure 4), and the resultant charge pump output is pumping current high, which, when integrated in the PLL low-pass filter, will push the tuning voltage of the VCO up. In this way, the –IN frequency will increase as the VCO increases, and the two PFD inputs will eventually converge or lock to the same frequency (Figure 5). If the frequency to –IN is higher than +IN, the reverse happens.Figure 4. A PFD out of phase and frequency lock.Figure 5. Phase frequency detector, frequency, and phase lock.Returning to our original example of the noisy clock that requires cleaning, the phase noise profile of the clock, free running VCXO, and closed-loop PLL can be modeled in ADIsimPLL.Figure 6. Reference noise.Figure 7. Free running VCXO.Figure 8. Total PLL noise.As can be seen with the ADIsimPLL plots shown, the noisy phase noise profile of the REFIN (Figure 6) is filtered by the low-pass filter. All the in-band noise contributed by the PLL reference and PFD circuitry is filtered out by the low-pass filter, leaving only the much lower VCXO noise (Figure 7) outside the loop bandwidth (Figure 8). When the output frequency is equal to the input frequency it creates one of the simplest PLL configurations. Such a PLL is called a clock clean-up PLL. For clock clean-up applications such as these, narrow (High Frequency Integer-N ArchitectureTo generate a range of higher frequencies, a VCO is used, which tunes over a wider range than a VCXO. This is regularly used in frequency hopping or in spread spectrum frequency hopping (FHSS) applications. In such PLLs, the output is a high multiple of the reference frequency. Voltage controlled oscillators contain a variable tuning element, such as a varactor diode, which varies its capacitance with input voltage, allowing a tuneable resonant circuit, which permitsU.S. Bancorp Dep.

It is most often used in chemical and process engineering to get information on fluid flow direction and connectivity between different equipment through the piping system. PFD helps to understand the chemical process, provide quality control and increase efficiency.A process flow diagram is used to get start to end understanding of how different types of equipment and chemicals work together in the process plant. PFD maps various tasks and helps you to understand which task is most important that needs to be done repetitively to perform to achieve some specific product.PFD helps to understand the process, provide quality control, and increase efficiency. It is used to get a top-down understanding of how different types of equipment and chemicals work in the industrial plant. It maps various tasks and shows what repeatable tasks you may need to perform to achieve a specific goal.Terminology frequently used for PFDHere is a list of some typically used term which is frequently used in the process flow diagram:Major Equipment: This includes Name and Tag numbers of equipment that has a major role in the plant. For example Pumps, Vaccum column, Crude Column, Compressors, Boilers, coolers, mixtures, etc.Process pipings: This is the network of pipes that transport fluid from one piece of equipment to another.Flow direction: This provides information about the direction of the flow of fluid. i.e. from which equipment fluid is taken the exit and make an entrance.Bypass system: This gives inputs about the alternate piping.

A range of frequencies to be generated (Figure 9). The PLL can be thought of as a control system for this VCO.A feedback divider is used to divide the VCO frequency to the PFD frequency, which allows a PLL to generate output frequencies that are multiples of the PFD frequency. A divider may also be used in the reference path, which permits higher frequency references to be used than the PFD frequency. A PLL like this is the ADF4108 from Analog Devices. The PLL counters are the second essential element to be considered in our circuit.Figure 9. Voltage controlled oscillator.The key performance parameters of PLLs are phase noise, unwanted by-products of the frequency synthesis process, or spurious frequencies (spurs for short). For integer-N PLLs, spurious frequencies are generated by the PFD frequency. A leakage current from the charge pump will modulate the tuning port of the VCO. This effect is lessened by the low-pass filter and the narrower this is, the greater the filtering of the spurious frequency. An ideal tone would have no noise or additional spurious frequency (Figure 10), but in practice phase noise appears as a skirt around a carrier, as shown in Figure 11. Single sideband phase noise is the relative noise power to the carrier in a 1 Hz bandwidth, specified at a frequency offset from the carrier.Figure 10. Ideal LO spectrum.Figure 11. Single sideband phase noise.Integer-N and Fractional-N DividerFor narrow-band applications, the channel spacing is narrow (typically Figure 12. PLL with dual modulus N counter. Table 1.

This identification number helps to get information about in and out of fluid in any equipment.all control valves and process critical valves are indicated in PFD.if there is any other system is connected with the main piping system, It is indicated in PFD.Composition of fluid in a systemLimitations of Process flow diagramThere is something that must not be included in a process flow diagram and henceforth we can get this information from PFD.Pipe class and isometric numbers.Piping code information.Instrument tag numbers.Minor bypass system and valve stations.Maintainance drain and vents.Pressure relief and pressure and pressure safety valves.Checklist for Process flow diagrambefore issuing a PFD to the process team following things must be check:Drawing number, page number, Latest revision, and revision purpose.Stream data table. e.g. correct units for measurement, flow ratesEquipment tags correctly formated, well placed, and match with P&ID.Instrument type and logic must be shown correctly.in case of any revision, old and new line numbers must be differentiated correctly.Brief on Piping and Instrumentation Drawing (P&ID)Piping and instrumentation drawing (P&ID) is also known as Process engineering flow schemes (PEFs). At first look, you may find PFD and P&ID similar but both have huge differences from each other. P&ID is more detailed compare to PFD.P&ID is a single-line schematic diagram that incorporates all equipment, instruments, valves, line size, and pipe specifications to give us the necessary information.P&ID is considered the most important document that controls all other related engineering drawings. A P&ID shows all piping networks including the exact physical sequence of branches, reducers, valves, instruments, types of equipment. A P&ID can be used to operate a complete piping system, as it gives information on piping with process flow and installed equipment and instrument with it.Information we gain from P&IDThe following list will give you an overview of the information we obtain from P&ID.Line number, Line size, and Specification of the piping system.Name and number of all equipment.Type of valve and identification of any special type of valve.Details about High point vent (HPV), Low point drain (LPD), Special fittings, sampling points, reducers, spectacles, blinds, etc.The flow direction of lines.Change in the spec in any line or spec break of a piping system.Equipment to equipment connection details.Instrument name and number in a piping system.Insulation or Jacketing requirements.Information of slope data if applicable for any line.Limitations of P&IDAlthough P&ID is much useful andComments
