Features

and achieves higher levels of performance at the same time being a driver for the design of low cost GPS applications. The RoadRunner ASIC contains circuitry to simultaneously track up to eight satellites. Each independent receiver channel within the ASIC can be commanded to acquire and continuously track a single spread spectrum signal using any of the GPS gold codes or the FAA WAASS PN codes. The ASIC performs the following major functions of a GPS receiver:
• Samples the down converted IF signal with a 1 bit A/D converter
• Down converts the signal to baseband by removal of the IF the carri.
