摘要： A data-pattern feedback mechanism is introduced into the peak detection process of an automatic frequency compensation system in a Gaussian Frequency Shift Keying (GFSK) modulated system, providing fast and accurate fine-stage automatic frequency compensation (AFC). Maximum positive and negative peak registers are updated with new values as necessary based on detection during a sequence of identical binary bit values (e.g., during a “00” for detection of maximum negative peak frequency, or during a “11” for detection of maximum positive peak frequency), in a particular data frame. As soon as an initial value is determined for both the maximum positive and negative peak frequencies (e.g., after the first occurrence of a “11” and a “00”, in any order), fine-stage automatic frequency compensation can be initiated. Subsequent adjustments to the VCO of the local oscillator will further refine the frequency offset towards the ideal of zero. Quick determination of the maximum positive and negative peak frequencies is made based on data pattern feedback in accordance with the principles of the present invention, allowing for a fast and accurate fine-stage automatic frequency compensation adjustment of a local oscillation clock signal.

摘要： A baseband clock synthesizer having particular use in a BLUETOOTH piconet device, having the capability of generating either 12 MHz or 13 MHz clock signals generated from any reference clock signal, e.g., 12.00, 12.80, 13.00, 15.36, 16.80, 19.20, 19.44, 19.68, 19.80, and 26.00 MHz. A fractional-N frequency divider is implemented with a PLL including a variable divider allowing the use of virtually any reference frequency input to generate a locked 156 MHz clock signal used as a basis for a 12 MHz or 13 MHz baseband clock signal. A residue feedback sigma-delta modulator provides a varying integer sequence to an integer divider in a feedback path of the PLL, effectively allowing division by non-integer numbers in the PLL. Thus, the PLL can be referenced to virtually any reference clock and still provide a fixed output clock signal (e.g., 12 or 13 MHz).

摘要： The present invention provides a baseband RF clock synthesizer having particular use in a BLUETOOTH piconet device, which has the capability of providing simple and accurate calibration of modulation path gain (KMOD) by introducing a dual-loop phase locked loop (PLL) in the RF clock signal synthesizer. The disclosed technique and apparatus controls the maximum frequency deviation by the difference of two locked frequencies, one frequency in each path of the dual-path PLL. Once the PLL is locked within some frequency error, the present technique and apparatus calibrates for the deviation of amplitude of the modulation due to the modulation path. Accordingly, modulation gain (KMOD) calibration is provided by adding an auxiliary loop to a PLL in an RF frequency synthesizer.

摘要： An improved automatic frequency compensation (AFC) technique and apparatus is provided for piconet applications, e.g., BLUETOOTH™ applications. In particular, the present invention provides an offset normalizer which normalizes frequency offset against maximum deviations. By normalizing the frequency offset, before determination of an adjustment of a local oscillator, the local oscillator adjustment becomes uncorrelated with respect to gain along the receiving path (including in a demodulator). Thus, extremely precise adjustments can be made to the local oscillator in a piconet device to provide extremely precise automatic frequency compensation.

摘要： In one embodiment, a method of integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset is disclosed. An RF connection is established between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit. The RF telephone handset is switched from performing as a telephony device to performing as a digital encoded-audio bit stream player. Digital encoded-audio bit stream music is played from the RF telephone handset. The digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player is muted when the RF telephone handset receives a telephone call. The RF telephone handset is switched from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active.
