XEMICS사에서 GPS용 chip을 소개하려 합니다. @ Item : XE1600 @ *RF Front End IC: Double conversion radio receiver with pseudo- baseband I/O outputs.Designed forGPS specifically. -Supply voltage : 2.7V -Low power : 20mW -Integrated VCO, no external components. -TSSOP-24 package. *ChannelCorrelator IC: Enhanced 8 channel GPS correlator, Outputs measurements such a pseudorange, carrier phase and doppler. -Supply voltage : 1.6V -Low power : < 5mW -Power management control for both Correlator and RF ICs. -SO 16 package. *Navigation Software: The navigation software API is processor and OS independent. It retrieves data from the correlator IC and produces: position, velocity and time information. -Runs on most 32bit CPUs. -Requires 2-4MIPS of processing power. -RS232 interface to the channel correlator IC. -Requires max 90kB of RAM. -Requires max 512kB of ROM ( Windows 9x, NT ) 참고로, Soft는 미국의 Trimble사에서 했습니다. 이런 GPS 제품외에도 Transceiver, Receiver, Bluetooth, Codec, Microcontroller 등 Low current 용 Chip 들이 많이 있습니다. 위 사항을 검토하시고, 궁금한 점이 계시면 언제라도 연락 주십시요. |
