20130021068 | Low-Voltage High-Speed Frequency Divider with Reduced Power Consumption - A low-voltage high-speed frequency divider substantially reduces the power required to generate a half-rate in-phase clock signal and a half-rate quadrature-phase clock signal by reducing the number of pairs of transistors that respond to a full-rate clock signal and a full-rate inverse clock signal. | 2013-01-24 |
20130021069 | DIRECT DIGITAL SYNTHESIZER FOR REFERENCE FREQUENCY GENERATION - A direct digital frequency synthesizer includes a multi-modulus divider, a numerically controlled oscillator and a programmable delay generator. The divider receives an input clock having an input pulse frequency and outputs some integer fraction of those pulses at an instantaneous frequency that is some integer fraction (1/P) of the input frequency. The divider selects between at least two ratios of P (1/P or 1/P+1) in response to a signal from the oscillator. The oscillator receives a value which is the accumulator increment (i.e. the number of divided pulse edges) required before an overflow occurs that causes the divider to change divider ratios in response to receiving an overflow signal. The oscillator also outputs both the overflow signal and a delay signal to the delay generator. The delay signal contains phase-dithering noise that is induced by input into the accumulator of an increment generated from a pseudo-random noise generator. | 2013-01-24 |

Furthermore, the frequency of the operational clock signal can be dynamically changed by changing the rate of asserting the enable signal relative to the root clock signal, without suspending operation of a functional unit receiving the operational clock signal. | 2013-01-24 |
20130021073 | DLL PHASE DETECTION USING ADVANCED PHASE EQUALIZATION - A system and method are disclosed to generate and terminate clock shift modes during initialization of a synchronous circuit (e.g., a delay-locked loop or DLL). Upon initialization, the DLL is entered into a ForceSL (Force Shift Left) mode and an Onlx mode (i.e., left shifting on each clock cycle). The feedback clock that tracks the phase of the reference clock (derived from the system clock) is initially delayed in a coarse phase detector prior to applying it to the coarse phase detection window. Two delayed versions of the feedback clock are sampled by the reference clock to generate a pair of phase information signals, which are then used to establish an advanced phase equal (APHEQ) signal. The APHEQ signal is used to terminate the ForceSL and Onlx modes, thereby preventing wrong ForceSL exit due to clock jitter or feedback path overshooting during Onlx exit, and resulting in faster DLL locking time. | 2013-01-24 |
