| 20100134152 | PHASE INTERPOLATOR - A phase interpolator receiving a first signal having an oscillation frequency Fin and providing a second signal having said oscillation frequency and having a phase shift Δφ with respect to the first signal which depends on a third signal. The interpolator includes a variable phase-shifter receiving the first signal and providing the second signal, the phase-shifter circuit includes an oscillator having a variable natural frequency Fo controlled by a fourth signal; a phase comparator capable of receiving the first and second signals and of providing a fifth signal representative of said phase shift; and a unit capable of providing the fourth signal which depends on the third and fifth signals | 06-03-2010 |
| 20100118192 | VIDEO SIGNAL SYNCHRONIZATION - The invention concerns receive circuitry for extracting horizontal and vertical synchronization signals from a digital synchronization signal associated with a video signal, the digital synchronization signal having a plurality of pulses, the receive circuitry including detection circuitry arranged to determine a first value indicative of the time delay between a timing edge of a first pulse and a timing edge of a second pulse of the digital synchronization signal; and a synchronization extraction block arranged to determine that one of the plurality of pulses is a vertical synchronization pulse based on a comparison between the first value and a reference value. | 05-13-2010 |
