DATA SHEET SE4150L: GPS Receiver IC Preliminary Datasheet Applications Product Description The SE4150L is a highly integrated GPS receiver IC High sensitivity / low power GPS / A-GPS apps. offering high performance and low-power operation in a Personal Navigation Devices (PNDs) , mobile wide range of low-cost applications. It is particularly phones, and GPS peripheral devices well-suited to high sensitivity L1-band GPS systems. The SE4150L is ideal for use in GPS receivers needing Features dual-antenna inputs. The SE4150L includes two RF Single-conversion L1-band GPS radio with inputs with integrated antenna switching and external active-antenna current detection. A high-linearity on- integrated IF filter chip LNA is used with one of the inputs, allowing the Integrated LNA with high-gain (20 dB typ.) and low SE4150L to be used in multi-function wireless systems, NF (0.9 dB typ.) without the need for additional external LNA devices. A Integrated antenna switching with active antenna fully integrated image-reject low-IF mixer is used with a current detection linear AGC, an on-chip IF filter, and a 2-bit analogue-to- Low cascaded system noise figure of 1.2 dB typical digital converter (ADC). 2-bit SIGN & MAG digital IF output 2.7 V - 3.6 V operation The SE4150L features two gain control modes, to optimize the performance of the LNA and mixer for Standby current <10 A systems which either require high signal handling, or Fully integrated PLL synthesizer, VCO & loop filter systems which need minimal supply current. compatible with 16.368 MHz ref. frequency 4 x 4 x 0.9 mm 24 pin QFN The SE4150L synthesizer is fully integrated including Pb-free, RoHS compliant and Halogen free the VCO and PLL loop-filter. The synthesizer can operate from a 16.368 MHz reference frequency, normally with an external TCXO. Ordering Information The SE4150L is optimized for operation from a 3.3 V Part No. Package Remark core power supply. It incorporates current-controlled low-spurious output buffers which may operate from a SE4150L-R 24 pin QFN Shipped in Tape & Reel separate external supply. Output buffers supply sufficient current to drive up to 15 pF load directly. Skyworks Solutions, Inc.
