SE4150L
GPS Receiver IC
Preliminary Datasheet
Product Description
Applications
ƒ
ƒ
The SE4150L is a highly integrated GPS receiver IC
offering high performance and low-power operation in a
wide range of low-cost applications. It is particularly
well-suited to high sensitivity L1-band GPS systems.
High sensitivity / low power GPS / A-GPS apps.
Personal Navigation Devices (PNDs) , mobile
phones, and GPS peripheral devices
The SE4150L is ideal for use in GPS receivers needing
dual-antenna inputs. The SE4150L includes two RF
inputs with integrated antenna switching and external
active-antenna current detection. A high-linearity onchip LNA is used with one of the inputs, allowing the
SE4150L to be used in multi-function wireless systems,
without the need for additional external LNA devices. A
fully integrated image-reject low-IF mixer is used with a
linear AGC, an on-chip IF filter, and a 2-bit analogue-todigital converter (ADC).

Single-conversion L1-band GPS radio with
integrated IF filter
Integrated LNA with high-gain (20 dB typ.) and low
NF (0.9 dB typ.)
Integrated antenna switching with active antenna
current detection
Low cascaded system noise figure of 1.2 dB typical
2-bit SIGN & MAG digital IF output
2.7 V - 3.6 V operation
Standby current <10 µA
Fully integrated PLL synthesizer, VCO & loop filter
compatible with 16.368 MHz ref. frequency
4 x 4 x 0.9 mm 24 pin QFN
Pb-free, RoHS compliant and Halogen free
The SE4150L features two gain control modes, to
optimize the performance of the LNA and mixer for
systems which either require high signal handling, or
systems which need minimal supply current.
The SE4150L synthesizer is fully integrated including
the VCO and PLL loop-filter. The synthesizer can
operate from a 16.368 MHz reference frequency,
normally with an external TCXO.

The SE4150L is optimized for operation from a 3.3 V
core power supply. It incorporates current-controlled
low-spurious output buffers which may operate from a
separate external supply. Output buffers supply
sufficient current to drive up to 15 pF load directly.
