美国国家半导体公司(NSC)主要设计、生产及销售高性能半导体器件,在混合模拟数字技术及通信技术方面居领先地位。SiRF及ABiC是该公司的商标,下面介绍该公司今年上半年度推出的最新器件。一、用于无线电通信的硅射频芯片美国国家半导体公司在今年二月宣布推出PLL-atinum~(TM)系列,锁相环(PLL)射频合成器。这是该公司为无线电收发器提供的一系列解决方案之一,PLLatinum硅放射频(SiRF~(TM))芯片属首批。 PLLatinum系列产品不但性能有所改良,价格也更为合理,而且耗电量减少了66％,包装面积亦缩小了51％。新产品的封装从16脚的JEDEC到20脚1.1mm
National Semiconductor Corporation (NSC) designs, manufactures and markets high-performance semiconductors, leading the way in mixed-analog digital and communications technologies. SiRF and ABiC are trademarks of the company and the following describes the latest devices the company introduced in the first half of this year. First, the radio frequency silicon chip for radio communications National Semiconductor announced in February this year, PLL-atinum ~ (TM) series, phase-locked loop (PLL) radio frequency synthesizer. This is one of a series of solutions that the company offers for radio transceiver, PLLatinum Silicon Radio Frequency (SiRF ~ (TM)) chip is the first batch. PLLatinum products not only improved performance, the price is more reasonable, and the power consumption decreased by 66%, packaging area has also been reduced by 51%. The new product package from JEDEC 16 feet to 20 feet 1.1mm
