Trimble Key Features and Benefits • 3.3 V for battery powered applications • Programmable power management • Sized for portable devices Lassen LP GPS Low power module for portable applications Trimble’s new Lassen ™ LP GPS is a low power miniature GPS receiver module that is ideal for power-conscious portable appli- cations. It is intended specifically for system designers and integra- tors who are developing the next generation of portable devices. This embedded technology gives the system developer the programming flexibility to achieve a significant reduction in power consumption. Power management The Lassen LP GPS features a new set of power management tools that puts the power budget decision in the developer’s hands. The developer now can deter- mine the best balance between operational frequency and power conservation for a particular application. In Schedule Track ™ operat- ing mode, the developer can program the unit to power up, quickly acquire satellites and out- put position to a schedule. After gathering satellite data and com- puting its location, the receiver may be directed to power down to a minimal mode of operation for a programmed interval or until awakened by a hardware interruption. Schedule Track provides hot start performance at a programmed interval or in response to a hardware event. Schedule Track mode provides an advantage over normal battery-backed fast start modes with automatic wakeup to maintain current satellite data for fastest possible acquisition. Schedule Track offers the lowest power consumption in a deep sleep mode but provides position data as quickly as possible when needed. Ease of integration Lassen LP GPS provides a choice of data protocols for maximum flexibility. The TSIP binary data protocol incorporates new power management features and provides maximum control over system operation. The TAIP and NMEA protocols are available where ASCII data is preferred. A secondary serial input port is available for RTCM SC-104 differential correction data for high accuracy applications. The Lassen LP GPS also incorporates Trimble’s antenna detection and protection circuit to monitor the condition of the antenna system. And a new high performance, miniature 3.3 V antenna is available for the Lassen LP GPS. Getting started The Starter Kit makes it easy to evaluate the Lassen LP GPS and begin development.

PRELIMINARY INFORMATION Features Applications • 4-Level Root Raised Cosine FSK Modulation • Half Duplex, 4800 to 19.2kbps • Increase Channel Bit Rate/Hz • Full Data Packet Framing • Impulse and NRZ Signal Modes • Enhanced Performance in Noisy Conditions • Error Detection and Error Correction • Low Power 3.3V/5.0V Operation • Wireless Data Terminals • Two Way Paging Systems • Digital Radio Systems • Wide Area Wireless Data Broadcasts • Point to Point Wireless Data Links MODEM DATA PUMP MX919B ANALOG TX DATA AND CONTROL BUS ANALOG RX RF RADIO DISCRIMINATOR MODULATOR SYSTEM APPLICATION PROCESSING HOST Cμ The MX919B is a low voltage CMOS device containing all of the baseband signal processing and Medium Access Control (MAC) protocol functions required for a high performance 4-level FSK Wireless Packet Data Modem. It interfaces with the modem host μC and the radio modulation/demodulation circuits to deliver reliable two-way transfer of the application data over a wireless link. The MX919B assembles application data received from the host μC, adds forward error correction (FEC) and error detection (CRC) information, and interleaves the result for burst-error protection. After automatically adding symbol and frame sync codewords, the data packet is converted into filtered 4-level analog signals for modulating the radio transmitter. In receive mode, the MX919B performs the reverse function using the analog signals from the receiver discriminator. After error correction and removal of the packet overhead, the recovered application data is supplied to the host μC. CRC detected residual uncorrected data errors will be flagged. A readout of the SNR value during receipt of a packet is also provided. The MX919B uses data block sizes and FEC/CRC suitable for applications where high-speed transfer of data over narrow-band wireless links is required. The device is programmable to operate at standard bit rates from a wide range of Xtal/clock frequencies. The MX919B may be used with a 3.0V to 5.5V power supply and is available in the following package styles: 24-pin SSOP (MX919BDS), 24-pin SOIC (MX919BDW), 24-pin PLCC (MX919BLH), and 24-pin PDIP (MX919BP). 4-Level FSK Modem Data Pump Page 2 of 47 MX919B PRELIMINARY INFORMATION ©2001 MX•COM, INC. www.mxcom.com Tele: 800 638 5577 336 744 5050 Fax: 336 744 5054 Doc. # 20480170.003 4800 Bethania Station Road, Winston-Salem, NC 27105-1201 USA All trademarks and service marks are held by their respective companies.
