PLL Application – FSK (Frequency Shift Keying) Demodulator A very useful application of the 565 PLL is as a FSK demodulator. In the 565 PLL the frequency shift is usually accomplished by driving a VCO with the binary data signal so that the two resulting frequencies correspond to the lo...
In this paper, we explore the design of a new architecture (without using any filters) of high-performance integrated FSK demodulator using ISPD PLL (inverse sine phase detector PLL). This architecture has clearly shown superior frequency performances, such as large bandwidth, large keep range, ...
It may be noted that a BER of 10-3 corresponds to a SNR around 12 dB, as expected from a nonideal FSK demodulator. Doc ID 12791 Rev 3 27/55 Board description AN2451 Figure 21. Measured BER vs. SNR curve (typical), white noise 1.00E-01 1.00E-02 BER vs. Signal to N...
RECEIVER IN IEEE 802.15.4-2006 MODE IEEE 802.15.4-2006 Reception When IEEE 802.15.4-2006 mode is selected, the output of the post demodulator filter is fed into a bank of correlators, which compare the incoming data sequences to the expected IEEE 802.15.4-2006 sequences. The IEEE 802.15....
A correlator demodulator is used for demodulation. An oversampled digital clock and data recovery (CDR) PLL is used to resynchronize the received bit stream to a local clock. RADIO PROFILES The ADF7024 radio profiles provide a set of optimized register settings for the ADF7024 radio. There ...

the FSK input signal is received by a digital phase locked loop demodulator which generates a pulse width modulated output signal. The pulse width of the PWM output is a function of the input signal frequency. The output of the digital PLL demodulator is then provided to a quantizer/translator...
