Title: Phase locked loop with fast start-up circuitry
Inventor: WOJEWODA IGOR
IPC: H03L7/12
Filed: 1998-12-17
Granted: 2003-06-01
Abstract: A phase-locked loop (PLL) circuit has a phase comparator for comparing the phases of a local clock frequency and a reference frequency to generate a control signal indicative of a direction of adjustment of the local clock frequency for reducing the phase difference between the two frequencies. A voltage controlled oscillator (VCO) of the PLL responds to application of a control voltage thereto generate an oscillation signal frequency from which the local clock frequency is derived. A loop filter responds to the control signal from the phase comparator to develop a control voltage for application to the VCO to adjust the local clock frequency in the direction indicated by the control signal to reduce the relative phase difference. The loop filter has a start-up circuit for detecting a selected edge of a cycle of the reference frequency after a predetermined number of cycles following commencement of operation or reset of the PLL circuit as being indicative of stabilization of the reference frequency, and is responsive to detection of such selected edge for promptly producing a linear boost of the control voltage from an initial level of substantially zero volts to a predetermined pull-up level exceeding the level of control voltage required to achieve phase locking. This reduces the time interval required to achieve phase locking, measured from the selected cycle edge. The loop filter is also responsive to the control voltage reaching the pull-up level to incrementally reduce the control voltage to the level required to achieve phase locking.

Title: UART clock wake-up sequence
Inventor: WEGNER GLENN
IPC: G06F13/38
Filed: 2000-10-09
Granted: 2002-12-21
Abstract: A UART with a clock oscillator that has a sleep mode. A counter is connected to the output of the clock oscillator. When the clock oscillator is awakened, the counter counts up to a specified count. Upon reaching the specified count, the output of the counter is enabled, which is connected to an interrupt line for generating an interrupt. In one embodiment, the IC need not be a UART, and no interrupt code (or a default code of all zeros or other default) is provided for the interrupt, thus eliminating the need for an additional interrupt register or additional room in existing interrupt registers. The user, such as a CPU, upon receiving the interrupt will look for an interrupt code. The absence of the interrupt code, combined with the user's knowledge that the integrated circuit was previously asleep, allows the user to determine that the interrupt indicates a clock wake-up.
