PointCharger GPS Receiver IC Preliminary Information

SE4100L PointChargerâ„¢ GPS Receiver IC Preliminary Information Applications Mobile phone & PDA accessories Portable navigation Personal security Security systems Asset tracking Telematics equipment 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. 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. 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. 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. Features 30 mW power consumption 4x4mm 24 pin LPCC package Single conversion radio with integrated IF filters On-chip, Gain switchabl.
