Publication number: 20090108891Abstract: Methods and apparatus for controlling a controlled oscillator using a phase-locked loop (PLL) or frequency-locked loop (FLL) having a digital loop filter with programmable filter parameters. An exemplary PLL (or FLL) includes a digital loop filter having one or more of the programmable filter parameters, which are changed by increments during operation in order to minimize disturbances (e.g., settling transients) as the loop bandwidth of the PLL is varied from a narrow loop bandwidth to a wide loop bandwidth, or vice versa. By changing the loop filter parameters in increments the loop bandwidth can be varied with substantially no perturbation. The end result is a much faster frequency switching time, improved settling dynamics, and predictable and stable loop operating performance. According to another aspect of the invention, one or more of the programmable filter parameters are changed in order to oppose a change in tuning sensitivity of the controlled oscillator (e.g.Type: ApplicationFiled: October 10, 2008Publication date: April 30, 2009Inventors: Wendell Sander, Brian Sander

Publication number: 20080309313Abstract: Handshaking circuits are provided in a communications cable and in a device operable to be mated with the communications cable. Before a device can utilize the power supply signal of such a communications channel, the two handshaking circuits must sufficiently identify one another over a power supply signal with a decreased voltage. The decreased voltage allows for a cable plug to be provided with a safe, protected power that cannot cause harm to a human. The decreased voltage also reduces the chance that a device can receive a primary power supply signal from the cable before the device sufficiently identifies itself. Accordingly, a laptop may be connected to a portable music player, but the voltage of the power supply signal provided by the laptop to the cable may be decreased on-cable until the handshaking circuit of the portable music player sufficiently performs a handshaking operation with a on-cable handshaking circuit.Type: ApplicationFiled: June 13, 2008Publication date: December 18, 2008Applicant: Apple Inc.Inventors: Doug Farrar, Lawrence Heyl, Brian Sander

Patent number: 7424083Abstract: The present invention, generally speaking, achieves noise spreading within a PLL using a dual-modulus prescaler by interleaving the division moduli. Within a given cycle, “ones” and “tens” are not all counted consecutively. Instead, ones and tens are interleaved. In one embodiment of the invention, the R count is doubled and the output of the R counter is toggled between high and low states. (The Q counter may remain unmodified.) In another embodiment of the invention, ones and tens are interleaved in accordance with a ratio q:r. By so interleaving the modulus, the effect is to spread the noise resulting from the output signal of the dual-modulus prescaler over a wider frequency range. The prescaler noise level is greatly reduced, particularly within the frequency band of the reference frequency.Type: GrantFiled: August 10, 2005Date of Patent: September 9, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Brian Sander, Earl W.

Patent number: 7227919Abstract: A digital circuit and method for forming number streams for frequency and/or phase comparison of digital or digitized signals, referred to herein as clock signals, where typically one of the clock signals is a known clock signal and another of the clock signal is an unknown clock signal. The unknown clock signal may be derived, for example, from a communications signal. The rate of the unknown clock signal may exceed the rate of the known clock signal. In an exemplary embodiment, an “alias” value (e.g., an integer 1, 2, 3, etc.) is applied to the circuit as an indication of the expected frequency range of the unknown clock signal. The number stream is formed accordingly.Type: GrantFiled: April 6, 2006Date of Patent: June 5, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Brian Sander

Patent number: 7222797Abstract: A promotional tool and a vehicle used to distribute products, information, gift certificates, prepaid phone cards, and coupons for businesses, corporations, retail establishments, universities, and sales personnel. A customized gift card displays professionally created artwork, logos and graphics that best portray the provider's intent for the overall design. The card is folded, die-cut and glued to receive a multimedia disc, gift certificate, coupon or phone card. A Multimedia Disc is included as a gift with each card. It is a digital medium that contains professionally recorded digital music and a variety of audio, video, and graphic information regarding the provider. It is placed in the card so the label which supports the card's overall design, is in view. A gift certificate, coupon, or a prepaid phone card can be placed in the card for easy accessibility and scanning by a retailer.Type: GrantFiled: September 11, 2003Date of Patent: May 29, 2007Inventors: Milton Dávila, James Brian Sanders, Charles Dembisky

Patent number: 7158494Abstract: The present invention, generally speaking, provides for true multi-mode operation enabling mode switching to be done on-the-fly, in real time. Ramping techniques are provided to fully ramp a communications signal down and then back up inside a guard period while switching from one mode to another so that signal glitches occur only while the signal is ramped down and so can be made negligible. In another aspect of the invention, an advantageous multi-mode communications platform having a polar modulation architecture is provided. Preferably, the platform is based on a multi-mode, predominantly digital, single-chip communications signal processor. A digital, phase-stable, frequency lock loop enables versatile, low-power operation.Type: GrantFiled: October 22, 2001Date of Patent: January 2, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Brian Sander, Wendell B.
