The device mainly consists of two components, one is voltage controller oscillator and other is phase detector. My multiplier should work from input range Hz to 2kHz ie. Hi, I am designing a frequency multiplier five times with the lm PLL.

Lock in range of pll. Why do you need a replacement? My input range is from Hz to Hz, which means my output range is Hz to Hz. The input signal goes in to the phase detector along with VCO feedback and this phase detector compares whether both signal are in same phase or frequency. Search the directory for faculty or staff members.

This is how a phase locked loop worksthe VCO output signal frequency will always tries to keep up with the input signal frequency. I need to use a lag-lead filter. Facilities Lab Research in the department is conducted in a variety of laboratories equipped with state-of-the-art equipment, with fatasheet funding coming from federal, state, and private sources.


Hi, I was wondering if someone could give me or point where to get pspice models for the following, lm Tags Phase Locked Llm565. Welcome to the ECE Store. Once the adjustment is done both the input signal frequency and VCO frequency will match.

Help me configure lag-lead filter.

In the device pin 2 and pin3 are inputs where we can connect the input analog signal but usually pin 3 will be grounded and pin2 is used as input. Previous 1 2 Next. RF, Microwave, Antennas and Optics:: This output voltage of PD is given to amplifier to amplify the voltage signal and the amplified voltage is given to VCO, which generates waveform whose frequency depends on magnitude of the given input voltage.

I have to use the lm chip. I was wondering if anyone could dataasheet me. Vatasheet simplest digital comparator is the XOR gate. I decided to design the transmitter side by a VCO. For the analog one, look at dstasheet datasheet for the lm And I plan using lm on the receiver side.

LM PLL IC Pinout, Features & Datasheet

What equations can i use? The circuit of a phase comparator both analog and digital.

For digital signals you can use XOR gate and run output through rc filter. Need Orcad Library for some ICs.

LM Datasheet(PDF) – National Semiconductor (TI)

Hi all, Now, i’m working on my final project. When a signal is given at the input, the frequency of both input signal and the VCO output is compared.


Engineering Program is accredited by: Take a look at the om565 for the 74HC If they are in phase or frequency the PD provides zero voltage output and if phase or frequency is present the PD provides positive output voltage. Our People Search the directory for faculty or staff members.

In addition to supporting the various labs in the EL datsaheet, we also provide equipment and manual check-out and a wide range of electronic components for sale. More complicated ones use edge-triggered flip-flops. I have orcade capture 9.

What is the import. Service Manuals, Requests, Repair Tips:: FSK demodulator with LM, 2 questions about the circuit Soldering Tips Helpful Link: Spring Semester, Monday — Friday: You can also see open positions in the department. Prices are subject to change without notice. However this means that most likely my loop gain KoKd will be greater then the inverse of the timing capacitor Co and resistor Ro.

Pin Configuration LM is a 14 pin device and the function of each pin is stated below.
