PT9250

48-channel Single Chip GPS Receiver

DESCRIPTION

FEATURES

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



Reception frequency : 1575.42 MHz ( L1 band, CA

code)

Reference clock (TCXO) frequency : 16.368 MHz

or 16.369 MHz

Best-in-class acquisition and tracking sensitivity,

TTFF and accuracy ¹.

Tracking sensitivity -159 dBm

Acquisition sensitivity -142 dBm

Cold start 33 sec, warm start 32 sec and hot

start 1 sec

represents

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.

5m position accuracy for autonomous²
