Hi, I am designing a frequency multiplier five times with the lm PLL. The circuit of a phase comparator both analog and digital. Engineering Program is accredited by: In the device pin 2 and pin3 are inputs where we can dagasheet the input analog signal but usually pin 3 will be grounded and pin2 is used as input. The sugestion above could fit your need with a lm IC.

The configuration of this filter can be seen on page 8 of the following datasheet: What equations can i use? Facilities Lab Research in the department is conducted in a variety of laboratories equipped with state-of-the-art equipment, with research funding coming from federal, state, and private sources.


The lm CN is available from National Semiconductor. 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. At this point I need an explanat. Why do you need a replacement?

Why do we dahasheet the 0. The ECE Store provides many services to electrical and computer engineering students in order to create a safe environment in which students have access to the equipment and parts they need.

Soldering Tips Helpful Link: This is how a phase locked loop worksthe VCO output signal frequency will always tries to keep up with the input signal frequency. FSK demod using LM TL — Programmable Reference Voltage. Need Orcad Library for some ICs. The device being cheap can be used in applications where cost is considered.

For the analog one, look at the datasheet for the lm Tags Phase Locked Loop.

I need to use a lag-lead filter. This output voltage of PD is given to amplifier to amplify the voltage signal and the amplified voltage is given pm565 VCO, which generates waveform whose frequency depends on magnitude of the given input voltage. For details on these services, please click the appropriate link from the menu on the left.


Our People Search datazheet directory for faculty or staff members. FSK demodulator with LM, 2 questions about the circuit More complicated ones use edge-triggered flip-flops.

RF, Microwave, Antennas and Optics:: You can also see open positions in the department. If they are in phase or frequency the Ml565 provides zero voltage output and if phase or frequency is present the PD provides positive output voltage.

The data sheet can be found at. I need to work out the values for C1, C2 and R2 if the cut off frequency is 1kHz.

And I plan using lm on the receiver side. Help me configure lag-lead filter.
