CXD2951GA-4

www.DataSheet4U.com CXD2951GA-4 Single Chip GPS LSI Description The CXD2951GA-4 is a dedicated single chip LSI for the GPS (Global Positioning System), satellitebased location measurement system. This LSI enables the configuration of a single chip system providing a cost-effective, low-power solution. Compared with conventional methods, position detection time and sensitivity are substantially improved with the use of an advanced signal processing scheme. With the integration of both the Radio and baseband blocks into a single CMOS IC, the CXD2951GA-4 is ideal for use in automotive, cellular handset, handheld navigation, mobile computing and other location-based applications. Features WAAS support 12-channel GPS receiver capable of simultaneously receiving 12 satellites Reception frequency: 1575.42MHz (L1 band, CA code) Reference clock (TCXO) frequency: 18.414MHz (GPS, Sony standard), The unique frequency of major applications is available, such as GSM and W-CDMA. (optional) 13.000MHz (GSM), 14.400MHz (CDMA), 16.368MHz (GPS), 19.800MHz (PDC/CDMA), 26.000MHz (GSM) 176 pin LFLGA (Plastic) Radio Image Rejection Mixer VCO Tank IF Filters Structure Silicon gate CMOS IC Absolute Maximum Ratings Supply voltage I/O IOVDD Supply voltage core CVDD Supply voltage radio VDD Input voltage VI Output voltage VO Operating temperature Topr Storage temperature Tstg –0.5 to +4.6 –0.5 to +2.5 –0.5 to +2.5 –0.5 to +6 –0.5 to +6 –40 to +85 –50 to +150 V V V V V °C ...
