  • Dual-modulus prescaler — A dual modulus prescaler is an electronic circuit used in high frequency synthesizer designs to overcome the problem of generating narrowly spaced frequencies that are nevertheless too high to be passed directly through the feedback loop of the… …   Wikipedia

  • R8C — Le Renesas R8C est un microcontrôleur 16 bits qui a été développé en tant que version plus petite et plus économique du M16C. Il conserve l architecture CISC 16 bits et le jeu d instructions du M16C, mais échange la vitesse par la taille, en… …   Wikipédia en Français

  • Frequency synthesizer — A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie… …   Wikipedia

  • Time to digital converter — In electronic instrumentation and signal processing, a time to digital converter (abbreviated TDC) is a device for converting a signal of sporadic pulses into a digital representation of their time indices. In other words, a TDC outputs the time… …   Wikipedia

  • Frequency divider — A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, fin, and generates an output signal of a frequency: where n is an integer. Phase locked loop frequency synthesizers… …   Wikipedia

  • Frequency counter — A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Since frequency is defined as the number of events of a particular sort occurring in a set period of time, measuring it is usually… …   Wikipedia

  • Media Independent Interface — The Media Independent Interface (MII) was originally defined as a standard interface used to connect a Fast Ethernet (i.e. 100 Mbit/s) MAC block to a PHY chip. The MII design has been extended to support reduced signals and increases speeds.… …   Wikipedia

  • Reduced Media Independent Interface — (RMII) is a standard that addresses the connection of Ethernet physical layer transceivers (PHY) to Ethernet switches. It reduces the number of signals/pins required for connecting to the PHY from 16 (for an MII compliant interface) to between 6… …   Wikipedia
