PT9250 Datasheet, PDF (1/7 Pages) Princeton Technology Corp – 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 4Mb flash
memory. 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.
