Appl. No.:

10/006516

Inventors:

Kuang Chi - San Jose CA, US
Ling Wang - Sunnyvale CA, US
Antony Davies - Campbell CA, US

Assignee:

Lattice Semiconductor Corporation - Hillsboro OR

International Classification:

H03D 3/24

US Classification:

375376, 375374, 375375

Abstract:

In a digital filter of a DPLL (digital phase locked loop) for minimizing the bit error rate for multiple communications protocols, a first reloadable register portion stores a TBW (total bandwidth) value programmed into the first reloadable register portion through a first port, and a second reloadable register portion stores a DBW (differential bandwidth) value programmed into the second reloadable register portion through a second port. An upcounter generates an UPCNT value by counting up each UP signal pulse generated by a phase transition detector when a first phase of a SDIN (serial data input) signal leads a second phase of a current ACLK (recovered clock) signal. A downcounter generates a DOWNCNT value by counting up each DOWN signal pulse generated by the phase transition detector when the first phase of the SDIN (serial data input) signal lags the second phase of the current ACLK (recovered clock) signal. One of a FWD (forward) signal or a BWD (backward) signal are asserted or are both not asserted depending on the UPCNT value and the DNCNT value in comparison to the TBW value and the DBW value. Another clock signal having a leading phase from the current ACLK signal is selected as a new ACLK (recovered clock) signal when the FWD signal is asserted.

International Classification:

H03D 3/24

US Classification:

375376, 375374, 375375

Abstract:

In one embodiment of the invention, a phase selection unit for generating a recovered clock signal (SCLK), a phase select signal generator generates a phase select signals in response to a FWD signal and a BWD signal from a digital filter. The digital filter asserts the FWD signal if the phase of a SDIN (serial digital input) signal leads the phase of the recovered clock signal, and asserts the BWD signal if the phase of the SDIN (serial digital input) signal lags the phase of the recovered clock signal. A multiplexer receives a number of given clock signals arranged in a predetermined phase order and outputs selected first and second output clock signals, each being one of the given clock signals. A phase interpolator receives the selected first and second output clock signals from the multiplexer to generate the recovered clock signal having a phase that is phase interpolated between the phases of the first and second output clock signals.

Inventors:

Ling Wang - Chicago IL, US

Assignee:

Koninklijke Philips Electronics, N.V. - Eindhoven

International Classification:

G08B 1/08

US Classification:

34053926, 34053922, 34053923, 3405391, 340540

Abstract:

In illuminated local areas occupants are actively detected to facilitate control of the illumination and possibly other local parameters such as temperature. The emitted light in each local area is uniquely modulated to identify the respective area. The modulated light is detected by any wearable occupancy detectors in the local areas, which transmit detector-locator signals to lighting control units, thereby identifying which local areas are occupied. These signals may also uniquely identify the respective detectors, thereby enabling a lighting system controller to determine the number and identities of the detectors in each local area.

International Classification:

H04B 1/40

US Classification:

455 88

Abstract:

A communication network includes a plurality of devices and a control unit for generating control signals to control the operation of the devices. Each device includes: a device operating circuit, a communication interface for receiving command signals for controlling operation of the devices, a control circuit coupled between the device operating circuit and the communication interface for controlling the operation of the device operating circuit part in dependency of said command signals, and a master integral to the device for receiving the control signals, for generating the command signals in response to the received control signals, and for transferring the command signals to the communication interfaces of the plurality of devices. The communication network activates one of the masters as an active master, and in case the active master fails, then it activates another master to take over as the active master.
