PT9250 48-channel Single Chip GPS Receiver DESCRIPTION The PT9250 is an advanced single chip GPS receiver to integrate baseband, RF and flash memory into the 7mm x 10mm package making for an extremely compact design. This advanced solution offers best-in-class acquisition & tracking sensitivity, TTFF and accuracy. The PT9250 architecture uses an FFT and Matched Filter that delivers performance equivalent to more than 75,000 correlators. This represents a quantum leap forward in GPS performance. The PT9250’s architecture enables unmatched TTFF at low signal levels. The PT9250 includes a powerful GPS DSP integrated with a 32-bit RISC microprocessor, 1Mb of SRAM and 4 Mb flash memories. The PT9250 also integrates a built-in low power RTC circuit for low power operation and battery backup RAM for satellite information. PTC supports full reference design, demonstration system, software evaluation tools and other supporting documentation.
