| Wolfson Unveils WM8580 and WM8581 Analog Signal Processors Two new multi-channel analog signal processors, combining the functions of up to six separate components, has been introduced by Wolfson Microelectronics. The WM8580 and WM8581 provide a highly flexible system for routing and converting multiple audio paths and formats, significantly simplifying audio path design and making it suited for LCD televisions, rewritable DVD systems, and AV receivers. The devices offer an ADC and multi-channel DAC, a 4:1 S/PDIF transceiver and a second audio interface for highly flexible audio signal routing. The products are built around a multi-channel audio CODEC - configured for 5.1 and 7.1 audio output, or providing the multiple independent outputs such as speaker, line out, headphone and auxiliary. Both devices feature a two-channel ADC; the WM8580 integrates a six-channel DAC and the WM8581 an eight-channel DAC. Each part features a 4:1 S/PDIF transceiver, with a maximum period jitter of 50ps, allowing them to lock onto and recover timing from poor quality input signals. The transceiver can therefore accept S/PDIF signals from a source even if the input signal is severely degraded. To address new customer requirements, such as HDMI, data recovery, memory card recording and surround sound processors, Wolfson has developed a second audio interface, which allows seamless digital connection to multiple DSPs and peripherals. The WM8580 and WM8581 CODECs have two- and three-wire serial or hardware control interfaces. The multiple DAC outputs have independent digital volume controls and the devices operate on 2.7-5.5 Volts for analogue functions and 2.7-3.6 Volts for digital. write your comments about the article :: © 2006 Computing News :: home page |
