XEMICS unveils world's lowest power ''SANDMAN CODEC'' geared to Bluetooth applications |

Xemics S.A., specializing in short-range wireless connectivity products
today announced the industry's lowest power CODEC for voice and audio
applications: the XE3000 series. Besides its ultra low power consumption and low
supply voltage, this product introduces a new function that detects if a voice
or audio signal is processed in the CODEC. Without a voice signal, parts of the
system can be put into sleep mode, thus the name, SANDMAN.
''The SANDMAN CODEC can be applied to all small battery-operated products where low power consumption and low supply voltage are key issues,'' said Sietse Wouters, Product Line Manager for the XE3000 series. '' Our CODECs have by far the lowest power consumption in the industry (< 2 mW), and the lowest supply voltage (1.8V). Most CODECs available today consume around 50 mW and need a supply voltage of around 3 V''.
The XE3000 series is ideally suited for application in Bluetooth and other types of wireless headsets or CD quality headphones. Other applications include handheld devices like GPS systems, PDAs, record and playback devices like MP3 players, and digital speakers. With a very small footprint (TSSOP), and direct connection to a microphone and speaker (no external amplifiers), the XE3000 series requires a minimum of low-cost external components (2 ceramic capacitors). Thus the overall system cost is lower than conventional solutions.
The XE3000 series consists of 4 different products: the XE3003 is an ADC (Analog to Digital Converter) and the XE3004 is a DAC (Digital to Analog Converter), both feature the Sandman function and are packaged in TSSOP20. The XE3005 is a CODEC (ADC + DAC) without Sandman function in TSSOP20 and the XE3006 is a CODEC with Sandman functions in TSSOP24.
To illustrate one of the benefits of the XE3000 SANDMAN CODECs, Sietse Wouters adds, ''A system based on a conventional CODEC would be listening permanently to the microphone, even when no voice is received. But the SANDMAN CODEC detects periods of silence so parts of the headset can be powered down. What that means is the wireless headset battery life is more than doubled''.
Development kit
The development kit for the XE3000 series (part number XE3000DVK) includes a board with the XE3006 SANDMAN CODEC, a serial interface to a PC (including cable), CD with complete product documentation and PC software to configure the CODEC, microphone and earphones. It allows the evaluation of the electrical as well as the audio performance and can even be connected to a CD-player through an optical interface. In order to demonstrate its low power consumption, it can be operated from a single lithium coin cell.
Price and availability
The XE3000
series of products are available today and are priced between USD 3.75 - 4.50
for 1 k pieces for the XE3003-XE3006 series. The development kit is available
today and is priced at USD 125.
