Patent number: 7945285Abstract: 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.Type: GrantFiled: February 16, 2010Date of Patent: May 17, 2011Assignee: Agere Systems Inc.Inventors: Qinghong Cao, Liang Jin, Wenzhe Luo, Jian Wu, Zhigang Ma

Patent number: 7471123Abstract: 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).Type: GrantFiled: April 20, 2005Date of Patent: December 30, 2008Assignee: Agere Systems Inc.Inventors: William Eric Holland, Wenzhe Luo, Zhigang Ma, Dale H. Nelson, Harold Thomas Simmonds, Lizhong Sun, Xiangqun Sun

Patent number: 6993300Abstract: 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.Type: GrantFiled: April 25, 2002Date of Patent: January 31, 2006Assignee: Agere Systems Inc.Inventors: Wenzhe Luo, Zhigang Ma
