Fastrax IT430 OEM GPS Receiver

The Fastrax IT430 is an OEM GPS receiver module, which provides the SiRFstar IV receiver (refI) functionality using the state of the art SiRF GSD4e chip (ROM variant). The module has ultra small form factor 9.6x9.6 mm, height is 1.85 mm nominal (2.15 mm max). The Fastrax IT430 receiver provides low power and very fast TTFF together with weak signal acquisition and tracking capability to meet even the most stringent performance expectations.

The module provides complete signal processing from antenna input to host port in either NMEA messages (ref II) or in SiRF OSP binary protocol (ref III). The module requires a single power supply VDD +1.8V. The host port is configurable to UART, SPI or I2C during power up. Host data and I/O signal levels are 1.8V CMOS compatible, inputs are 3.6V tolerable.
