Cirrus Logic has introduced a mobile for smart phones and consumer electronics applications, audio IC right.
The CS42L73 is a high quality, ultra low-power audio codec smart phone applications. The CS35L0X is an analog input, mixed-D type for mobile communication equipment and portable speaker amplifier.
Both products are based on Cirrus Logic's technology in the portable audio products, and help solve the challenges of multiple systems to extend battery life, improved audio quality in the field of design experience, simplify management and reduce electromagnetic interference signals, so that smaller form factors, according to Cirrus logic.
"Our strategy is to continue to develop innovative products, such as CS42L73 and CS35L0X, the solution fields, especially in the lower system power consumption of smart phones and portable devices, the real problem, while maintaining high quality," Jason Rhode said the president of Cirrus Logic CEO in a statement.
CS42L73 codec smart phones, to save energy and extend the unloading, such as the audio signal routing and processing tasks normally reserved for the application processor, battery life. Available today CS42L73 is also gold in the European XMM 6260 Infineon Technologies AG from the reference design.
The CS42L73 with two ADC and 4 DAC on an advanced, high quality, based on a number of Delta Sigma architecture. The DAC output can drive five, including the ground as the center of the stereo headphones and H type line driver, ear, and low electromagnetic interference drive hands-free speaker driver, the company said. The analog front-end supports both line and two programmable gain amplifiers and automatic level control for microphone input of Cirrus Logic Inc. said.
Mobile phone applications to meet the high quality audio, while maintaining low noise and power consumption challenges, Cirrus Logic Inc. has announced that it has developed a CS35L00 (+6 / +12 dB gain), CS35L01 (+6 dB gain), and CS35L03 (+12 dB gain) Mixed Class D Audio Amplifier. Use of closed-loop Delta Sigma architecture and patent-pending hybrid D class technology, combined with a Class D amplifier efficiency and output current range of low idle power consumption and EMI the smallest usually found only in the AB class amplifiers.
CS35L00 amplifier quiescent current consumption of the family only, which is 40 percent less than the nearest competitor 0.9 mA.
The CS42L73, this is a 64-ball WLCSP packages to offer volume production, priced at 1.95 U.S. dollars, 10000, Cirrus Logic Inc. said. The CS35L00 is a 10-pin DFN package, CS35L01/03 in 9 ball WLCSP package, and pin-compatible, the company said. The CS35L00 is the price of 35 cents per unit, 10 000 and CS35L01/03 are 320 000 cents.
