Cosmic Circuits today announced that its PLL solutions are being used by Enverv, a provider of advanced SoC solutions for smart grid, metering and control applications. Long term jitter as small as 2ps RMS has been Thus the PLL Period Jitter (PJ, also known as short term jitter) must be known in order for the circuit to have sufficient timing margin. It is important to The following figure shows a simplified PLL block diagram. Phase Locked Loop or PLL is the feedback system used in Frequency Shift keying, Stereo decoding etc. Wireless transmitter circuit design based on TRF4900 Chip integrated voltage-controlled oscillator (VCO), phase-locked loop (PLL) and the reference oscillator, requires only minimal external components to form a complete transmitter. It also finds applications in Telemetry, Wide band FM circuits, Frequency multiplication applications etc. RF system design: system specifications, wireless communications (review) & system architectures. A phase-locked loop (PLL) is a feedback control circuit that synchronizes the phase of a generated signal with that of a reference signal. The Silicon Creations Fractional-N PLL (block diagram shown in Figure 2) suppresses this noise with the addition a feed-forward compensator that feeds directly into the loop filter, and is able to achieve jitter in Fractional mode very close to that achieved in integer mode.
