PointCharger™ GPS Receiver IC

Preliminary Information

Applications

Product Description

The SE4100 is an integrated GPS receiver designed to

receive the L1 signal at 1575.42MHz. The receiver has

a low IF architecture, and integrates all of the amplifier,

oscillator, mixer and demodulation functions.

Asset tracking

The external component count is low, requiring just a

16.368MHz crystal and 11 passive components in its

minimum configuration. This and the 24 pin LPCC

package result in a very small circuit footprint, which is

complemented by just 30mW operating power.

Features

ꢀ

30 mW power consumption

Two digitally controlled shutdown modes enable either

to part to be powered down entirely or for just the 16

MHz clock supply to the baseband processor to be

maintained.

4x4mm 24 pin LPCC package

Single conversion radio with integrated IF filters

On-chip, Gain switchable LNA

Low LNA noise figure, 1.3dB typ.

A switchable gain LNA enables the SE4100 to be used

with a local passive antenna or with a remote active

antenna without changing the circuit configuration. The

on-chip VCO and PLL generates the required LO

frequency from the external 16.368MHz crystal. All of

the VCO and LO chain is integrated. An image reject

mixer downconverts the RF signal to a 4.092MHz IF.

The integrated IF filter feeds a combiner, limiter and

output latch. The output signal is a 1-bit quantized

4.092 MHz digital IF at CMOS levels.

On chip crystal oscillator can be powered up

independently
