NXP推出射频转换元件-BF1108

恩智浦半导体射频转换元件(BF1108)的推出，提供了家庭用户一个聪明既简易的节能方式，当天线讯号通过相关的录制装置(例如DVD-R、HDD-R、VCR 或 DVR)连结时，人们通常让装置处于待机模式，避免失去电视的讯号。在采用了BF1108作为射频转换的功能后，在关掉录制装置的电源时仍能保有天线讯号，同时可以继续收看电视。通过这个方式，不仅可以节省能源，也可节省一笔金钱的支出，假设将录制装置电源关掉平均每年可节省$4美金，平均每台录制装置可使用寿命5年，若每台装置配有一颗射频转换元件(BF1108)的话，即可节省$20美金的支出。全球目前有超过4千万台的录制装置，预估将带来将近8亿美金的效益。

如果您正打算设计相关的录制装置，恩智浦射频转换元件(BF1108)将会为您创造出额外的价值。

How：
At the moment the recording device is powered on, the BF1108 opens allowing the RF signal to travel to the recording device and then on to the TV tuner. When the recorder is turned off, the BF1108 closes, looping the signal directly to the TV tuner. Reception remains constantly fed to the TV.

Energy saving：
NXP has sold more than 75 million BF1108 devices over 10 years. At the beginning of that time, a recording device in the standby mode consumed on average 50 kWh of power a year. Over time, recording devices have improved on energy consumption, but still use about 10 kWh a year in standby mode alone. Assuming that a recording device lasts for about 5 years, the energy saving total is easily calculated. In total, the BF1108 already saved almost 4,000 GWh, which is the equivalent of the yearly energy consumption of more than 1 million households in Europe. It also saved consumers in total almost $ 800.000.000 (based on European energy cost prices). The sales of our BF1108 continue to grow strong, selling 25 million pieces in 2008. The energy saving of these types has yet to start!
