Phase Lock Loop Design The Projects Forum. My senior design project for my Electrical Engineering degree is to build a discrete PLL that locks between 1kHz and 100kHz. A PLL is a solid-state tuner: no tubes*, no crystals, no nada. With microphone and audio input of the amplifier, adjustable input level. In a PLL circuit, the number of LPFs is reduced to one to reduce mounting area and pin number, and to simplify design. *While this version used vacuum tubes, it's latter implementation used semi-conductors. Negative feedback control system where the frequency of the output fout tracks fin and the rising edges of the input and output clocks quickly move toward alignment. That's a diagram of his version to the upper right. So i suppose a 2nd order LPF will suffice. Internal circuit diagram of each PLL block is as shown in figure given below. Everything must be made using discrete parts (no ICs, no op-amps). Transmitting power can switch between 2W and 15W. The control board is designed with high performance MCU STC series?its performance is better than AT89C2051. Other carrier-grade features include SONET-compatible jitter peaking (0.1dB max) and circuitry to minimise output clock phase transients during reference switching. However i am not sure on how to design the VCO LPF MULTIPLIER circuit using inductors, resistors, capacitors e.t.c can anyone help? For the purposes of use as a regulator of the transceiver operating frequency,. Phase-locked loops (PLLs) are widely used on designs such as frequency synthesizers and clock recovery circuits. Connections:- The output of FM receiver is connected to all four inputs of PLL blocks (1 to 4). The motherboard is applied with chip BH1415F, which is the new-generation integrated NC FM stereo radio chip by ROHM, built-in PLL frequency, audio pre-emphasis, limiter and low pass filter circuit.
