Product Description

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.

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 on-

chip 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-to-

digital converter (ADC).

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.
