The article discusses the power requirements and all kinds of other HD developments shown at CES, including the SiPort chip, which is also available to manufacturers now. Both consume between 120 and 180 mW of power. Both chips are intended for integrated devices. If you qualify for an online subscription, you can read the entire article. "Don''t be put off by high power drain" "I have just purchased my second Bush DAB radio (I left the first in a hotel room and never had it returned) I have also owned the Ferguson version which, I believe is the same but for the case and battery compartment (Ferg uses 3 AAs). Yes they do use a lot of power but this is understandable as the units use Digital to analogue converters which are very power hungrydevices (feel the heat coming off your Sky Box!). The trick is to use rechargable batteries (we should all do this anyway for environmental reasons) - I use mine in bed every night and frequently fall asleep with the unit on; using 2700 mAhr batteries I get about 2 nights sleep out of them - Just have two sets - one on charge and one on drain." http://tinyurl.com/2uxork "Nokia Music Internet Radio: Listen to the World Through Internet Radio" http://europe.nokia.com/A4668051 No matter what, digital to analogue converters are battery-hogs. No one, is going to be interested in HD chipsets with cell phone providers starting to provide access to Internet Radio. LOL! XM receivers have DACs and use less than 10 mA. |
